== Café simulation ==

=== '''Problem''' ===
In the simulation the goal was to find out whether it is possible to run a café with predefined spatial disposition being just one person.

To find out it was necessary to obtain data about possible ingoing flow of customers and to define activities conducted by the staff.

It was expected that the simulation should help find out, if the first hypothesis will show as faulty, the ideal/better conditions (number of personnel, number of seats, possible adjustment to a process setting etc.)

=== '''Tool''' ===
As a tool to do so the Simprocess was selected as it provides user with possibility to design processes and measure use of resources.

=== '''The Café''' ===

==== '''Spatial disposition''' ====
Spatial disposition of the Café is depicted on the image below. The designer proposes to create a space with 24 seats.
[[File:renderCafeM.png]]

==== '''Gathering of referential data''' ====
To be able to simulate inflow of customers, it was necessary to get some referential data. Several people were asked kindly to participate in this project. Some of them did not respond, some of them did not want to share this kind of data as they probably find them sensitive. Finally, data from a place in Prague and a café in Pardubice were retrieved.

As the Prague establishment has a bit different concept, I decided not to use it directly.

Café located at city of Pardubice on the other hand was nearly perfect, as it has pretty much the same spatial proportions. Also, it is not that big agglomeration as Prague is and it is in the same region as our Café.

The number of seats at that place is '''24''', which is the same as the number on the first visualization of the examined Café.

Important data provided by the operational of the venue in Pardubice are following:

· The average amount of customers per day is 80

· There are two peaks during the day: 12:30 - 14:30 and 15:30 - 18:00

To find a measure between the café in Pardubice and our café, a metric was created.

I took number of citizens of the municipality where the café is situated and divided it by the amount of competitors plus our café which results into a value of 1565.

When done the same, but on the data from Pardubice city, the value is 2941.

The resulting ratio is 53%. With that number I multiplied the average daily traffic of the café in Pardubice which results in '''43''' visitors a day on average in the examined café. This amount was marked as a ''Realistic scenario.'' The '''80''' visitors per day was titled ''Optimistic scenario.''

=== '''The simulation''' ===
The runtime of the simulation is set to one day – beginning at 00:00:00 and ending and 23:59:59.

==== '''Defined entities''' ====
· '''Zákazník''' = customer

· '''Working_power''' = auxiliary entity that helps to simulate a creation of untidiness with the direct connection to the customers

· '''Dish_collecting_workingpower''' = also auxiliary entity that helps to simulate need for collection of the dishes. It is in a separate entity as it was necessary to make it higher priority than the regular cleaning (people would probably not like the dishes staying on the tables)

==== '''Defined resources''' ====
· '''Zaměstnanec''' = staff member

· '''Místo =''' a seat

==== '''Staff activities''' ====
In order to simulate the time of the visitors in the café and also the time of the staff member, it was necessary to create a list of activities that are usually executed in such an environment. To do that correctly, I involved my friends that worked/work in a café and I also utilized the fact that I personally worked in a similar establishment for few months.

We created a list of activities which we evaluated with time needed for doing those. These activities are the ones that involve staff member. Activities that are conducted only by the customers were not discussed.

==== '''Defined activities (all of a type ''Delay)/ used resources / duration value (minutes)'':''' ====
This activity is being carried out by the auxiliary entity which has priority 3 (high).

· Collection of dirty dishes / Zaměstnanec / Nor(1.0,0.2,1)

'''Dining process'''

These activities are being carried out by the primary customer entity with high priority.

· Making an order / Zaměstnanec, Místo / Nor(1.5,0.3,1)

· Order deliver / Zaměstnanec, Místo / Log(5.0,1.2,45)

· “Enjoying the perfect product” (meaning – consumption) / Místo / Nor(40.0,12.0,1)

· Conversation with the customer / Zaměstnanec / Int(0,2)

'''Cleaning and maintenance'''

These activities are being carried out by auxiliary entity with lower priority.

· Dishwasher manipulation / Zaměstnanec / Nor(4.0,0.5,1)

   This activity batches “dirty dishes” of 10 customers.

· Putting dishes into shelves / Zaměstnanec / (1)

· Cleaning a table / Zaměstnanec / Nor(1.0,0.2,12)

   This activity is batched on the average amount of seats by one table so it simulates cleaning of a table once there is one free.

'''Payment'''

This activity is being carried out by the primary customer entity with high priority.

· Payment / Zaměstnanec / Nor(1.3,0.3,1)

   The activity uses only Zaměstnanec as it is expected that customers will pay at the counter before they leave.

==== '''Defined entry schedule / ''Optimistic scenario''''' ====
· '''The normal''' - Poi(3.5,1) every 1 hour / 11:00 – 21:00

· '''Peak1''' - Poi(4,3) every 25 minutes / 12:30 – 14:30

· '''Peak2''' - Poi(4,2) every 25 minutes / 15:30 – 18:00

==== '''Defined entry schedule / ''Realistic scenario''''' ====
· '''The normal''' - Poi(2.1,1) every 1 hour / 11:00 – 21:00

· '''Peak1''' – Poi(2.5,3) every 35 minutes / 12:30 – 14:30

· '''Peak2''' - Poi(2.5,2) every 35 minutes / 15:30 – 18:00

=== '''Simulation results''' ===
''Every simulation was done 100 times and the report was generated from the average of these simulations.''

==== '''Optimistic / 1 personnel''' ====
Starting with the optimistic scenario trying to prove the one person hypothesis, we can find out that just by observing the simulation, there are customers staying in the system even after the generation of new tries stops. The last entity leaves the system slightly after 23:00, which is more than two hours after the last “customers were let it. Also, this one simulation was not that strong with just 63 entries generated. Besides this fact, that people are staying in the system that long, there was also lot of “cleaning and maintenance” to do, which the single staff person did not manage to finish before midnight.

When looking at the report, we can see that number of visitor varied between 47 and 110. Right next to it we can also see quite alarming finding that on average 16 customers remained somewhere in the system and in one case it was even 71 customers.

Another information that report gives us is a fact, that on average at one time, there was 24 customers in the system, but maximum case was 48 customers, which is the double of capacity of the café. Also, on average there was 18 people waiting for resources at one time.

All this tells us that it is not possible to run this big venue with just one person as a staff member.

Optimistic scenario with just one personnel: NO.

==== '''Optimistic / 2 personnel''' ====
The second try with 1 extra resource in staff members looks more promising. With similar numbers of customers, there is on average just 2 people left in the system. There is also on average just 2 people waiting for resources at one time, which sounds acceptable.

The average customer spends 1,5 hour in the café, which also sounds way more reasonable. With waiting time for resources with length of half an hour, there is still some space for improvement.

As we can see, the resources are far from being used to the full potential, but this might be explained by the irregular occurrence of guest and their tendency to come in groups.

The staff members spend most time on delivering the orders and preparing the food with being present for the payment as the last most time consuming activity.

Another interesting finding is the amount of time spent on different activities. On average customers spend approximately 1 hour and 12 minutes in the dining process and about 8 minutes paying.

In overall, there is still lot of space for improvement, but as a rough estimation, this simulation shows that in case the amount of customers would rise to the optimistic level, it would be necessary to incorporate two staff members.

==== '''Realistic / 1 personnel''' ====
Based on the results of previous simulations, there is an expectation that with nearly half the amount of customers coming in the café, one person should manage to take care of the venue.

With roughly 44 people visiting the café on average, there were 2 individuals left in the system by the end of the day. Maximum count of people in the café at one time is 10, but on average its 5 customers.

Customers spent usually nearly two hours in the café, with roughly 1,5 hour eating and 13 minutes paying, which leaves us with roughly 17 minutes spent on waiting for resources.

Again, the personnel is not utilized by 100%, but only 30,1%.

Overall, it seems like it is possible to run the café while being just one person in case the assumptions about amount of guests are correct. Based on the wealth of the region and on the fact, that the café is meant to be located in a quite small town, it is with high probability that the realistic scenario is more likely to be true than the optimistic one.

=== '''Propositions for improvement of the simulation''' ===
· The generated customer should be transformed after going through the gate that simulates creation of groups of customers as it would not include the time spent waiting at the gate to the total time spent in the system, which would make the output data more clear.

· Find a way to simulate real behavior of people sitting to the tables, as people usually do not come to a café to sit with a stranger.

· Simulate a version with one full time customer and one extra that help would to cover only the peaks.

=== '''Practical advices resulting from the simulation''' ===
· Hire a “cleaning woman” that helps to deal with the dishes and with the closing of the shop by the end of the day.

· Get prepared for bigger groups of people coming in at one time – do the cleaning and other maintenance while there is not that many people in the venue.

· In the future, when there are running costs known already, they can be included to the simulation.

· Cleaning a table / Zaměstnanec / Nor(1.0,0.2,12)

   This activity is batched on the average amount of seats by one table so it simulates cleaning of a table once there is one free.

'''Payment'''

This activity is being carried out by the primary customer entity with high priority.

· Payment / Zaměstnanec / Nor(1.3,0.3,1)

   The activity uses only Zaměstnanec as it is expected that customers will pay at the counter before they leave.

=== '''Simulation results''' ===
''Every simulation was done 100 times and the report was generated from the average of these simulations.''

==== '''Optimistic / 1 personnel''' ====
Starting with the optimistic scenario trying to prove the one person hypothesis, we can find out that just by observing the simulation, there are customers staying in the system even after the generation of new tries stops. The last entity leaves the system slightly after 23:00, which is more than two hours after the last “customers were let it. Also, this one simulation was not that strong with just 63 entries generated. Besides this fact, that people are staying in the system that long, there was also lot of “cleaning and maintenance” to do, which the single staff person did not manage to finish before midnight.

When looking at the report, we can see that number of visitor varied between 47 and 110. Right next to it we can also see quite alarming finding that on average 16 customers remained somewhere in the system and in one case it was even 71 customers.

Another information that report gives us is a fact, that on average at one time, there was 24 customers in the system, but maximum case was 48 customers, which is the double of capacity of the café. Also, on average there was 18 people waiting for resources at one time.

All this tells us that it is not possible to run this big venue with just one person as a staff member.

Optimistic scenario with just one personnel: NO.

==== '''Optimistic / 2 personnel''' ====
The second try with 1 extra resource in staff members looks more promising. With similar numbers of customers, there is on average just 2 people left in the system. There is also on average just 2 people waiting for resources at one time, which sounds acceptable.

The average customer spends 1,5 hour in the café, which also sounds way more reasonable. With waiting time for resources with length of half an hour, there is still some space for improvement.

As we can see, the resources are far from being used to the full potential, but this might be explained by the irregular occurrence of guest and their tendency to come in groups.

The staff members spend most time on delivering the orders and preparing the food with being present for the payment as the last most time consuming activity.

Another interesting finding is the amount of time spent on different activities. On average customers spend approximately 1 hour and 12 minutes in the dining process and about 8 minutes paying.

In overall, there is still lot of space for improvement, but as a rough estimation, this simulation shows that in case the amount of customers would rise to the optimistic level, it would be necessary to incorporate two staff members.

==== '''Realistic / 1 personnel''' ====
Based on the results of previous simulations, there is an expectation that with nearly half the amount of customers coming in the café, one person should manage to take care of the venue.

With roughly 44 people visiting the café on average, there were 2 individuals left in the system by the end of the day. Maximum count of people in the café at one time is 10, but on average its 5 customers.

Customers spent usually nearly two hours in the café, with roughly 1,5 hour eating and 13 minutes paying, which leaves us with roughly 17 minutes spent on waiting for resources.

Again, the personnel is not utilized by 100%, but only 30,1%.

Overall, it seems like it is possible to run the café while being just one person in case the assumptions about amount of guests are correct. Based on the wealth of the region and on the fact, that the café is meant to be located in a quite small town, it is with high probability that the realistic scenario is more likely to be true than the optimistic one.

=== '''Propositions for improvement of the simulation''' ===
· The generated customer should be transformed after going through the gate that simulates creation of groups of customers as it would not include the time spent waiting at the gate to the total time spent in the system, which would make the output data more clear.

· Find a way to simulate real behavior of people sitting to the tables, as people usually do not come to a café to sit with a stranger.

· Simulate a version with one full time customer and one extra that help would to cover only the peaks.

=== '''Practical advices resulting from the simulation''' ===
· Hire a “cleaning woman” that helps to deal with the dishes and with the closing of the shop by the end of the day.

· Get prepared for bigger groups of people coming in at one time – do the cleaning and other maintenance while there is not that many people in the venue.

· In the future, when there are running costs known already, they can be included to the simulation.

== Café simulation ==

=== '''Problem''' ===
In the simulation the goal was to find out whether it is possible to run a café with predefined spatial disposition being just one person.

To find out it was necessary to obtain data about possible ingoing flow of customers and to define activities conducted by the staff.

It was expected that the simulation should help find out, if the first hypothesis will show as faulty, the ideal/better conditions (number of personnel, number of seats, possible adjustment to a process setting etc.)

=== '''Tool''' ===
As a tool to do so the Simprocess was selected as it provides user with possibility to design processes and measure use of resources.

=== '''The Café''' ===

==== '''Spatial disposition''' ====
Spatial disposition of the Café is depicted on the image below. The designer proposes to create a space with 24 seats.
[[File:renderCafe.png]]

==== '''Gathering of referential data''' ====
To be able to simulate inflow of customers, it was necessary to get some referential data. Several people were asked kindly to participate in this project. Some of them did not respond, some of them did not want to share this kind of data as they probably find them sensitive. Finally, data from a place in Prague and a café in Pardubice were retrieved.

As the Prague establishment has a bit different concept, I decided not to use it directly.

Café located at city of Pardubice on the other hand was nearly perfect, as it has pretty much the same spatial proportions. Also, it is not that big agglomeration as Prague is and it is in the same region as our Café.

The number of seats at that place is '''24''', which is the same as the number on the first visualization of the examined Café.

Important data provided by the operational of the venue in Pardubice are following:

· The average amount of customers per day is 80

· There are two peaks during the day: 12:30 - 14:30 and 15:30 - 18:00

To find a measure between the café in Pardubice and our café, a metric was created.

I took number of citizens of the municipality where the café is situated and divided it by the amount of competitors plus our café which results into a value of 1565.

When done the same, but on the data from Pardubice city, the value is 2941.

The resulting ratio is 53%. With that number I multiplied the average daily traffic of the café in Pardubice which results in '''43''' visitors a day on average in the examined café. This amount was marked as a ''Realistic scenario.'' The '''80''' visitors per day was titled ''Optimistic scenario.''

=== '''The simulation''' ===
The runtime of the simulation is set to one day – beginning at 00:00:00 and ending and 23:59:59.

==== '''Defined entities''' ====
· '''Zákazník''' = customer

· '''Working_power''' = auxiliary entity that helps to simulate a creation of untidiness with the direct connection to the customers

· '''Dish_collecting_workingpower''' = also auxiliary entity that helps to simulate need for collection of the dishes. It is in a separate entity as it was necessary to make it higher priority than the regular cleaning (people would probably not like the dishes staying on the tables)

==== '''Defined resources''' ====
· '''Zaměstnanec''' = staff member

· '''Místo =''' a seat

==== '''Staff activities''' ====
In order to simulate the time of the visitors in the café and also the time of the staff member, it was necessary to create a list of activities that are usually executed in such an environment. To do that correctly, I involved my friends that worked/work in a café and I also utilized the fact that I personally worked in a similar establishment for few months.

We created a list of activities which we evaluated with time needed for doing those. These activities are the ones that involve staff member. Activities that are conducted only by the customers were not discussed.

==== '''Defined activities (all of a type ''Delay)/ used resources / duration value (minutes)'':''' ====
This activity is being carried out by the auxiliary entity which has priority 3 (high).

· Collection of dirty dishes / Zaměstnanec / Nor(1.0,0.2,1)

'''Dining process'''

These activities are being carried out by the primary customer entity with high priority.

· Making an order / Zaměstnanec, Místo / Nor(1.5,0.3,1)

· Order deliver / Zaměstnanec, Místo / Log(5.0,1.2,45)

· “Enjoying the perfect product” (meaning – consumption) / Místo / Nor(40.0,12.0,1)

· Conversation with the customer / Zaměstnanec / Int(0,2)

'''Cleaning and maintenance'''

These activities are being carried out by auxiliary entity with lower priority.

· Dishwasher manipulation / Zaměstnanec / Nor(4.0,0.5,1)

   This activity batches “dirty dishes” of 10 customers.

· Putting dishes into shelves / Zaměstnanec / (1)

· Cleaning a table / Zaměstnanec / Nor(1.0,0.2,12)

   This activity is batched on the average amount of seats by one table so it simulates cleaning of a table once there is one free.

'''Payment'''

This activity is being carried out by the primary customer entity with high priority.

· Payment / Zaměstnanec / Nor(1.3,0.3,1)

   The activity uses only Zaměstnanec as it is expected that customers will pay at the counter before they leave.

==== '''Defined entry schedule / ''Optimistic scenario''''' ====
· '''The normal''' - Poi(3.5,1) every 1 hour / 11:00 – 21:00

· '''Peak1''' - Poi(4,3) every 25 minutes / 12:30 – 14:30

· '''Peak2''' - Poi(4,2) every 25 minutes / 15:30 – 18:00

==== '''Defined entry schedule / ''Realistic scenario''''' ====
· '''The normal''' - Poi(2.1,1) every 1 hour / 11:00 – 21:00

· '''Peak1''' – Poi(2.5,3) every 35 minutes / 12:30 – 14:30

'''ArchiMate''' ({{IPAc-en|'|a:r|k|I|m|ei|t}} {{Respell|AR|ki|mayt}}; originally from '''Archi'''tecture-Ani'''mate''') is an open and independent [[enterprise architecture]] [[modeling language]] to support the description, analysis and visualization of architecture within and across [[business]] domains<ref name="Archi">[https://web.archive.org/web/20100323073120/http://www.archimate.org/en/about_archimate/what_is_archimate.html What is ArchiMate?] at archimate.org from archive.org. Accessed April 19, 2014</ref> in an unambiguous way.

ArchiMate is a technical standard from [[The Open Group]] and is based on the concepts of the [[IEEE 1471]] standard. It is supported by various tool vendors and consulting firms. ArchiMate is also a registered trademark of The Open Group.
The Open Group has a certification program for ArchiMate users, software tools and courses.<ref name="ArchiMate-certification">[http://www.opengroup.org/certifications/archimate/ ArchiMate Certification] at opengroup.org. Accessed January 11, 2014.</ref>

ArchiMate distinguishes itself from other languages such as [[Unified Modeling Language]] (UML) and [[Business Process Modeling Notation|Business Process Modeling and Notation]] (BPMN) by its [[enterprise modelling]] scope.<ref>Pallab Saha (2008) ''Advances in Government Enterprise Architecture''. p.39.</ref>

Also, UML and BPMN are meant for a specific use and they are quite heavy – containing about 150 (UML) and 250 (BPMN) modeling concepts whereas ArchiMate works with just about 50 (in version 2.0). The goal of ArchiMate is to be ”as small as possible”, not to cover every edge scenario imaginable. To be easy to learn and apply, ArchiMate was intentionaly restricted “to the concepts that suffice for modeling the proverbial 80% of practical cases".<ref name=":0">{{Cite web|url=http://pubs.opengroup.org/architecture/ArchiMate3-doc/chap03.html#_Toc489945967|title=ArchiMate 3.0.1 Specification|last=|first=|date=|website=Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>

== Overview ==
ArchiMate offers a common language for describing the construction and operation of [[business processes]], organizational structures, [[information flow]]s, IT systems, and technical infrastructure. This insight helps the different [[Project stakeholder|stakeholders]] to design, assess, and communicate the consequences of decisions and changes within and between these business domains.

The main concepts and relationships of the ArchiMate language can be seen as a framework, the so-called Archimate Framework:<ref>[http://pubs.opengroup.org/architecture/archimate2-doc/chap02.html#_Toc371945144 The ArchiMate Framework], in: ''ArchiMate® 2.1.'' Accessed 06.2015.</ref> It divides the [[enterprise architecture]] into a business, application and technology layer. In each layer, three aspects are considered: active elements , an internal [[structure]] and elements that define use or communicate [[information]].

One of the objectives of the ArchiMate language is to define the relationships between concepts in different architecture domains. The concepts of this language therefore hold the middle between the detailed concepts, which are used for modeling individual domains (for example, the [[Unified Modeling Language|UML]] for modeling [[software]] products),<ref>Zoran Stojanović et al. (2007). ''Service-oriented Software System Engineering''. p.145-146.</ref> and [[BPMN]], which is used for business process modeling.

== History ==
ArchiMate is partly based on the [[IEEE 1471]] standard. It was developed in the Netherlands by a project team from the [[Telematica Instituut]] in cooperation with several [[Netherlands|Dutch]] partners from government, industry and academia. Among the partners were Ordina, [[Radboud Universiteit Nijmegen]], the Leiden Institute for Advanced Computer Science (LIACS) and the [[Centrum Wiskunde & Informatica]] (CWI). Later, tests were performed in organizations such as [[ABN AMRO]], the Dutch Tax and Customs Administration and the [[Stichting Pensioenfonds ABP|ABP]].<ref>Telematica Instituut (2006) ''[https://web.archive.org/web/20130928105158/https://doc.novay.nl/dsweb/Get/Document-64437/ Annual Report 2005].'' p.7. Accessed 18 jan 2009.</ref>

The development process lasted from July 2002 to December 2004, and took about 35 man years and approximately 4 million euros. The development was funded by the Dutch government (Dutch Tax and Customs Administration), and business partners, including [[ABN AMRO]] and the ABP Pension Fund.<ref name="Snair007">[http://earchpal.wordpress.com/2008/08/03/archimate-its-time-has-come/ ArchiMate : Its Time Has Come?] Enterprise Architecture Demystified.

== ArchiMate Framework ==

=== Core Framework ===
The main concepts and elements of the ArchiMate language are being presented as ArchiMate Core Framework<ref>{{Cite web|url=http://pubs.opengroup.org/architecture/ArchiMate3-doc/chap02.html#_Toc489945953|title=ArchiMate 3.0.1 Specification Chapter 2|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>. It consists of three layers and three aspects. This creates a matrix of combinations. Every layer has its Passive structure, Behavior and Active structure aspects.

==== Layers ====
[[File:ArchiMate framework.jpg|thumb|[[View model]] of ArchiMate Architectural Framework.]]

ArchiMate has a layered and service-oriented look on architectural models. The higher layers make use of services that are provided by the lower layers. Although, at an abstract level, the concepts that are used within each layer are similar, we define more concrete concepts that are specific for a certain layer. In this context, we distinguish three main layers:<ref name="Archi"/><ref name="Snair007"/>
* The ''Business layer'' is about [[business processes]], services, functions and events of business units. This layer "offers products and services to external customers, which are realized in the organization by business processes performed by business actors and roles".
* The ''Application layer'' is about [[software application]]s that "support the components in the business with application services".
* The ''Technology layer'' deals "with the [[computer hardware|hardware]] and [[communication]] infrastructure to support the Application Layer. This layer offers infrastructural services needed to run applications, realized by computer and communication hardware and system software"<ref name=":0" />.

Each of these main layers can be further divided in sub-layers. For example, in the Business layer, the primary business processes realising the products of a company may make use of a layer of secondary (supporting) business processes; in the Application layer, the end-user applications may make use of generic services offered by supporting applications. On top of the Business layer, a separate Environment layer may be added, modelling the external customers that make use of the services of the organisation (although these may also be considered part of the Business layer).

In line with service orientation, the most important relation between layers is formed by use relations, which show how the higher layers make use of the services of lower layers. However, a second type of link is formed by realisation relations: elements in lower layers may realise comparable elements in higher layers; e.g., a ‘data object’ (Application layer) may realise a ‘business object’ (Business layer); or an ‘artifact’ (Technology layer) may realise either a ‘data object’ or an ‘application component’ (Application layer).

==== Aspects ====

* ''Passive structure'' stands for all the objects on which action (behavior) is conducted. In the Business Layer the example would be information objects, in the Application Layer data objects and in the Technology Layer, they could stand for physical objects.
* ''Behavior'' stands all the processes and functions done by the actors. „''Structural elements are assigned to behavioral elements, to show who or what displays the behavior''“<ref name=":1">{{Cite web|url=http://pubs.opengroup.org/architecture/archimate3-doc/chap03.html#_Toc489945970|title=ArchiMate 3.0.1 Specification Chapter 3|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>.
* ''Active Structure'' represents f.e. business actors, devices or application components. These can be called subjects of activity, structural elements that display some behavior.

=== Full Framework ===
The Full ArchiMate framework is enriched by the ''Physical Layer'', which was added to allow modeling of “physical equipment, materials, and distribution networks”<ref name=":1" /> and wasn’t present in the previous version.

The ''Implementation and Migration Layer'' adds elements that allow architects to model a state of transition, to mark parts of the architecture that are temporary for the purpose, as the name says, of implementation and migration.

''Strategy Layer'' adds three elements: Resource, Capability and Course of Action. These elements help to incorporate strategic dimension to the ArchiMate language by allowing to depict usage of resources and capabilities in order to achieving some strategic goals.

As last addition, there is a ''Motivation Aspect'' that allows different stakeholders to describe motivation of specific actors or domains, which can be quite important when looking at one thing from several different angles. It adds several elements like stakeholder, value, driver, goal, meaning etc.

== Archimate Language ==
The ArchiMate language is formed as a top-level and is hierarchical. On the top, there is a model. A model is collection of concepts. A Concept can be either an Element or a Relationship. Element can be either of Behavior type, Structure, Motivation or so-called Composite Element (which means that it does not fit just one aspect of the framework, but two or more).

The functionality of all the concepts without dependency on the specific layer is described by '''Generic metamodel'''. This layer non-specific description of concepts is useful when trying to understand mechanics of the Archimate language.

=== Concepts ===

==== Elements ====
The generic elements are distributed into the same categories as the layers<ref>{{Cite web|url=http://pubs.opengroup.org/architecture/archimate3-doc/chap04.html#_Toc489945977|title=ArchiMate 3.0.1 Specification Chapter 4|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>:

* Active structure elements
* Behavior elements
* Passive structure elements
* Motivation elements

As described earlier in the Layers section, active structure element represents an entity that is capable of performing behavior. Based on two levels of abstraction that ArchiMate provides, it is possible to distinguish between ''internal active structure elements'', which stands for active elements within the system like f.e. business actors and ''external active structure elements'' which stands for elements that carry out the behavior outside the system - f.e. interfaces.

Behavior elements can be as well internal or external. ''Internal behavior element'' is the one that stands for an activity carried out by some ''active structure elements'' within the system. Archimate defines f.e. ''Process'' and ''Function'' elements. ''External behavior'' a service that the whole system provides to the environment.

Passive structure element is an object, that can be used by the behavior elements (and thus ''active structure elements'' can perform behavior on them). They usually stand for information objects in the business layer and data objects in the application layer, but they may also be used to represent physical objects.

As described in the previous chapter, Motivation elements are answering the question ''Why?,'' they are trying to give a context and explain the motives behind the architecture''.'' They can be of a ''active structure'', as a Stakeholder and also of a ''passive structure'' - Value, Meaning, Driver, etc.

==== Relationships ====
ArchiMate sets several types of relationships that can connect different sets of source and target concepts. The classification of relationships is following:

* Structural relationships – create a static construction of concepts of the same or different types
* Dependency relationships – define how elements can support other elements
* Dynamic relationships – model behavioral dependencies
* Other relationships

=== General structure of models within the different layers ===
[[File:Core concepts of the ArchiMate language.jpg|thumb|Core concepts of the ArchiMate language (Lankhorst, 2013).]]

The general structure of models within the different layers is similar. The same types of concepts and relations are used, although their exact nature and granularity differ.

First, it is necessary to distinguish the structural or static aspect and the behavioural or dynamic aspect. Behavioural concepts are assigned to structural concepts, to show who or what displays the behaviour. For example, role, interface and collaboration are assigned to business process, organisational service and business interaction, respectively.

Second, there must be a distinction between an external view and an internal view on systems. When looking at the behavioral aspect, these views reflect the principles of service orientation. The service concept represents a unit of essential functionality that a system exposes to its environment. For the external users, only this external functionality, together with non-functional aspects such as the quality of service, costs etc., are relevant. Services are accessible through interfaces, which constitute the external view on the structural aspect.

Although for the external users only the external view is relevant, the design of organisations or systems and their internal operations and management also requires knowledge about the internal realisation of the services and interfaces. For this realisation, it is necessary to make a distinction between behavior that is performed by an individual structural element (e.g., actor, role component, etc.), or collective behavior (interaction) that is performed by a collaboration of multiple structural elements.

=== Notation ===
The ArchiMate separetes the languages concepts from their notation (contrary to the UML or BPMN). As there are different groups of steakholders, they may need different notations. This might be confusing, but it is solved by the viewpoint mechanism.

Although ArchiMate doesnt stress the only one notation, it comes with one and it aims to those "''used to existing technical modeling techniques such as ERD, UML, or BPMN, and therefore resembles them"''<ref name=":1" />.

==== Use of colors ====
In ArchiMate, the use of colors is not explicitly set, however, it is usual that colors are used to distinguish between the different layers.

* Yellow for the Business Layer
* Blue for the Application Layer
* Green for the Technology Layer

==== Letters ====
As another way to distinguish to which layer which element belongs, according to the Full Framework layers, there can also be a capital letter in the left top corner of the element that stands for the specific layer (M for the Motivation, B for the Business, etc.)

==== Element shape ====
The shape of elements helps to distinguish the right Aspect. Structure elements have square corners, Behavior elements come with round corners. Diagonal corners indicate a motivational element.<ref name=":1" />

== Viewpoints ==
A great premise of the latest version of ArchiMate are the Views and Viewpoints. They allow stakeholders to define specific conditions like concepts, analysis techniques, models, and visualizations – a viewpoint, from which the model should be perceived.

A view (or a [[view model]]) “''is defined as a part of an Architecture Description that addresses a set of related concerns and is tailored for specific stakeholders”''<ref>{{Cite web|url=http://pubs.opengroup.org/architecture/archimate3-doc/chap14.html#_Toc489946131|title=ArchiMate 3.0.1 Specification Chapter 14|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>. In return, the stakeholders give their feedback which creates a bi-directional communication.

Ultimately, this allows the stakeholders/architects to communicate their ideas and concerns easily with others. Also by reducing the “view” by setting the right conditions and intentionally limiting the perspective, it is easier solve specific problems and also, for stakeholders from specific areas it makes the model easier to read.

== Benefits and pitfalls of the ArchiMate ==

==== Benefits ====

* Ensures consistency across all architecture models (business domains)
* Allows the stakeholders to be involved in design, to asses all the requirements and it works well as a communication tool
* Richness of the tool – core framework, motivation extension that enriches the core with reasons why and implementation and migration extension
* It is regularly updated with quite broad base of certified users
* 3.0.1 version supports IOT features
* It provides user with Viewpoints

==== '''Pitfalls''' ====

* IT centred - as it is closely tied up with the world of IT, it might be hard to create an architecture of a non-IT company that is producing a physical products (partly solved by the latest version, but still complicated)

== Exchange file format ==
A standard model exchange file format has been developed for ArchiMate 2.1 and 3.0 models.<ref name = "ExchangeFileFormat">{{cite web|url=http://www.opengroup.org/xsd/archimate/|title=ArchiMate® Model Exchange File Format for the ArchiMate 3.0 Modeling Language|website=www.opengroup.org}}</ref> This is an [[XML]]/[[XML#XML Schema|XSD]] based file format, and is intended for exchange rather than a persistent file format.

== ArchiMate Framework ==

=== Core Framework ===
The main concepts and elements of the ArchiMate language are being presented as ArchiMate Core Framework<ref>{{Cite web|url=http://pubs.opengroup.org/architecture/ArchiMate3-doc/chap02.html#_Toc489945953|title=ArchiMate 3.0.1 Specification Chapter 2|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>. It consists of three layers and three aspects. This creates a matrix of combinations. Every layer has its Passive structure, Behavior and Active structure aspects.

==== Layers ====
[[File:ArchiMate framework.jpg|thumb|[[View model]] of ArchiMate Architectural Framework.]]

ArchiMate has a layered and service-oriented look on architectural models. The higher layers make use of services that are provided by the lower layers. Although, at an abstract level, the concepts that are used within each layer are similar, we define more concrete concepts that are specific for a certain layer. In this context, we distinguish three main layers:<ref name="Archi"/><ref name="Snair007"/>
* The ''Business layer'' is about [[business processes]], services, functions and events of business units. This layer "offers products and services to external customers, which are realized in the organization by business processes performed by business actors and roles".
* The ''Application layer'' is about [[software application]]s that "support the components in the business with application services".
* The ''Technology layer'' deals "with the [[computer hardware|hardware]] and [[communication]] infrastructure to support the Application Layer. This layer offers infrastructural services needed to run applications, realized by computer and communication hardware and system software"<ref name=":0" />.

Each of these main layers can be further divided in sub-layers. For example, in the Business layer, the primary business processes realising the products of a company may make use of a layer of secondary (supporting) business processes; in the Application layer, the end-user applications may make use of generic services offered by supporting applications. On top of the Business layer, a separate Environment layer may be added, modelling the external customers that make use of the services of the organisation (although these may also be considered part of the Business layer).

In line with service orientation, the most important relation between layers is formed by use relations, which show how the higher layers make use of the services of lower layers. However, a second type of link is formed by realisation relations: elements in lower layers may realise comparable elements in higher layers; e.g., a ‘data object’ (Application layer) may realise a ‘business object’ (Business layer); or an ‘artifact’ (Technology layer) may realise either a ‘data object’ or an ‘application component’ (Application layer).

==== Aspects ====

* ''Passive structure'' stands for all the objects on which action (behavior) is conducted. In the Business Layer the example would be information objects, in the Application Layer data objects and in the Technology Layer, they could stand for physical objects.
* ''Behavior'' stands all the processes and functions done by the actors. „''Structural elements are assigned to behavioral elements, to show who or what displays the behavior''“<ref name=":1">{{Cite web|url=http://pubs.opengroup.org/architecture/archimate3-doc/chap03.html#_Toc489945970|title=ArchiMate 3.0.1 Specification Chapter 3|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>.
* ''Active Structure'' represents f.e. business actors, devices or application components. These can be called subjects of activity, structural elements that display some behavior.

=== Full Framework ===
The Full ArchiMate framework is enriched by the ''Physical Layer'', which was added to allow modeling of “physical equipment, materials, and distribution networks”<ref name=":1" /> and wasn’t present in the previous version.

The ''Implementation and Migration Layer'' adds elements that allow architects to model a state of transition, to mark parts of the architecture that are temporary for the purpose, as the name says, of implementation and migration.

''Strategy Layer'' adds three elements: Resource, Capability and Course of Action. These elements help to incorporate strategic dimension to the ArchiMate language by allowing to depict usage of resources and capabilities in order to achieving some strategic goals.

As last addition, there is a ''Motivation Aspect'' that allows different stakeholders to describe motivation of specific actors or domains, which can be quite important when looking at one thing from several different angles. It adds several elements like stakeholder, value, driver, goal, meaning etc.

== Archimate Language ==
The ArchiMate language is formed as a top-level and is hierarchical. On the top, there is a model. A model is collection of concepts. A Concept can be either an Element or a Relationship. Element can be either of Behavior type, Structure, Motivation or so-called Composite Element (which means that it does not fit just one aspect of the framework, but two or more).

The functionality of all the concepts without dependency on the specific layer is described by '''Generic metamodel'''. This layer non-specific description of concepts is useful when trying to understand mechanics of the Archimate language.

=== Concepts ===

==== Elements ====
The generic elements are distributed into the same categories as the layers<ref>{{Cite web|url=http://pubs.opengroup.org/architecture/archimate3-doc/chap04.html#_Toc489945977|title=ArchiMate 3.0.1 Specification Chapter 4|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>:

* Active structure elements
* Behavior elements
* Passive structure elements
* Motivation elements

As described earlier in the Layers section, active structure element represents an entity that is capable of performing behavior. Based on two levels of abstraction that ArchiMate provides, it is possible to distinguish between ''internal active structure elements'', which stands for active elements within the system like f.e. business actors and ''external active structure elements'' which stands for elements that carry out the behavior outside the system - f.e. interfaces.

Behavior elements can be as well internal or external. ''Internal behavior element'' is the one that stands for an activity carried out by some ''active structure elements'' within the system. Archimate defines f.e. ''Process'' and ''Function'' elements. ''External behavior'' a service that the whole system provides to the environment.

Passive structure element is an object, that can be used by the behavior elements (and thus ''active structure elements'' can perform behavior on them). They usually stand for information objects in the business layer and data objects in the application layer, but they may also be used to represent physical objects.

As described in the previous chapter, Motivation elements are answering the question ''Why?,'' they are trying to give a context and explain the motives behind the architecture''.'' They can be of a ''active structure'', as a Stakeholder and also of a ''passive structure'' - Value, Meaning, Driver, etc.

==== Relationships ====
ArchiMate sets several types of relationships that can connect different sets of source and target concepts. The classification of relationships is following:

* Structural relationships – create a static construction of concepts of the same or different types
* Dependency relationships – define how elements can support other elements
* Dynamic relationships – model behavioral dependencies
* Other relationships

=== General structure of models within the different layers ===
[[File:Core concepts of the ArchiMate language.jpg|thumb|Core concepts of the ArchiMate language (Lankhorst, 2013).]]

The general structure of models within the different layers is similar. The same types of concepts and relations are used, although their exact nature and granularity differ.

First, it is necessary to distinguish the structural or static aspect and the behavioural or dynamic aspect. Behavioural concepts are assigned to structural concepts, to show who or what displays the behaviour. For example, role, interface and collaboration are assigned to business process, organisational service and business interaction, respectively.

Second, there must be a distinction between an external view and an internal view on systems. When looking at the behavioral aspect, these views reflect the principles of service orientation. The service concept represents a unit of essential functionality that a system exposes to its environment. For the external users, only this external functionality, together with non-functional aspects such as the quality of service, costs etc., are relevant. Services are accessible through interfaces, which constitute the external view on the structural aspect.

Although for the external users only the external view is relevant, the design of organisations or systems and their internal operations and management also requires knowledge about the internal realisation of the services and interfaces. For this realisation, it is necessary to make a distinction between behavior that is performed by an individual structural element (e.g., actor, role component, etc.), or collective behavior (interaction) that is performed by a collaboration of multiple structural elements.

=== Notation ===
The ArchiMate separetes the languages concepts from their notation (contrary to the UML or BPMN). As there are different groups of steakholders, they may need different notations. This might be confusing, but it is solved by the viewpoint mechanism.

Although ArchiMate doesnt stress the only one notation, it comes with one and it aims to those "''used to existing technical modeling techniques such as ERD, UML, or BPMN, and therefore resembles them"''<ref name=":1" />.

==== Use of colors ====
In ArchiMate, the use of colors is not explicitly set, however, it is usual that colors are used to distinguish between the different layers.

* Yellow for the Business Layer
* Blue for the Application Layer
* Green for the Technology Layer

==== Letters ====
As another way to distinguish to which layer which element belongs, according to the Full Framework layers, there can also be a capital letter in the left top corner of the element that stands for the specific layer (M for the Motivation, B for the Business, etc.)

==== Element shape ====
The shape of elements helps to distinguish the right Aspect. Structure elements have square corners, Behavior elements come with round corners. Diagonal corners indicate a motivational element.<ref name=":1" />
[[File:Příklad.jpg]]

== Viewpoints ==
A great premise of the latest version of ArchiMate are the Views and Viewpoints. They allow stakeholders to define specific conditions like concepts, analysis techniques, models, and visualizations – a viewpoint, from which the model should be perceived.

A view (or a [[view model]]) “''is defined as a part of an Architecture Description that addresses a set of related concerns and is tailored for specific stakeholders”''<ref>{{Cite web|url=http://pubs.opengroup.org/architecture/archimate3-doc/chap14.html#_Toc489946131|title=ArchiMate 3.0.1 Specification Chapter 14|last=|first=|date=|website=The Open Group|archive-url=|archive-date=|dead-url=|access-date=20.1.2019}}</ref>. In return, the stakeholders give their feedback which creates a bi-directional communication.

Ultimately, this allows the stakeholders/architects to communicate their ideas and concerns easily with others. Also by reducing the “view” by setting the right conditions and intentionally limiting the perspective, it is easier solve specific problems and also, for stakeholders from specific areas it makes the model easier to read.

== Benefits and pitfalls of the ArchiMate ==

==== Benefits ====

* Ensures consistency across all architecture models (business domains)
* Allows the stakeholders to be involved in design, to asses all the requirements and it works well as a communication tool
* Richness of the tool – core framework, motivation extension that enriches the core with reasons why and implementation and migration extension
* It is regularly updated with quite broad base of certified users
* 3.0.1 version supports IOT features
* It provides user with Viewpoints

==== '''Pitfalls''' ====

* IT centred - as it is closely tied up with the world of IT, it might be hard to create an architecture of a non-IT company that is producing a physical products (partly solved by the latest version, but still complicated)

== Exchange file format ==
A standard model exchange file format has been developed for ArchiMate 2.1 and 3.0 models.<ref name = "ExchangeFileFormat">{{cite web|url=http://www.opengroup.org/xsd/archimate/|title=ArchiMate® Model Exchange File Format for the ArchiMate 3.0 Modeling Language|website=www.opengroup.org}}</ref> This is an [[XML]]/[[XML#XML Schema|XSD]] based file format, and is intended for exchange rather than a persistent file format.

== Simulation proposal ([[Xvegm00|Xvegm00]]) Simulation of semi-intelligent algae (Not approved yet)==

This Netlogo simulation aims to copy the behaviour of a symbiotic organism called physarum polycephalum. Physarum is actually a single cell organism, but when two or more cells meet, their membranes merge together and they work together to efficiently gather nutrition and multiply.
This simulation should mimic the spread and path creation of the algae, as well as its ability to solve the shortest path problem.

Topic/goal: '''Optimal size of HDD for virtual Digitization server'''

Definition of the problem: 
- each day an average of 47 batches of documents is being processed by the server with average size per batch of 32 MB (calculated from customers server) 
- the number of batches changes a lot and cant be easily predicted so it will have to be taken into consideration (from sample: lowest number of batches scanned in a day is 13, the highest is 134) 
- the average size is not changing that much 
- (batch contains original scanned documents, extracted data in XML files, log files, enhanced images and searchable PDF) 
- backup images from scanning will stay on the server for 6 months (those are ''additional'' ~50 % of the batch size) 
- successfully processed batches older than 14 days are deleted every day 
- for precaution lets say around 5% of batches wont be processed correctly 
- those will stay on the server and will be processed every month by admins

:::: I would base the simulation on how much one person interacts with others, depending on this variable the person would have some probability of getting sick thus the number of ill people would increase thus the probability of him getting sick would be higher and higher.

Topic: '''Social and economical effects of reunification of North & South Korea''' 
'''Definition of the problem:''' 
Let's hope one day South and North Korea will be reunited. That would mean a big fluctuation of people between the two separated states: 
- North Koreans will migrate to South Korea area, look for flats, try to get jobs and receive welfare. 
- South Koreans will invest in North Korea area and create jobs and factories there. 
''I would like to simulate:'' 
- What will be the population ratio of the two areas per square meter. 
- How many North Koreans will move to South Korea area after the reunification and how many of them will be on welfare and how much that will cost the new reunited country. 
- How much will the suicide rate change in Korea after the reunification since it's a known fact that defected North Koreans have a high suicide rate due to the fact they have difficulties to adjust to the new lifestyle and process propaganda-free information. 
- What will be the housing situation after the reunification. 
- How will the GDP of the new country possibly develop. 
- Possibly how much money will be needed from international help.

:::: OK, I thought about how I would realize the simulation in NetLogo and I see you were right about it being too complicated. So I tried to simplify my model even more to be doable:
:::: - The patches will be divided proportionally by area of the two countries, they will also be characterized by a certain portion of the initial GDP as their wealth.
:::: - The turtles representing Koreans will have initial wealth (also based on the initial GDP) and they will be migrating towards one of the two states based on their inclination to migrate to the other country. This inclination will be calculated randomly based on the East-West Germany migration data and their wealth.
:::: - On each tick, the simulation will determine:
::::: - if the turtle (Korean) has a job (landed one, got fired, is working, or didn't get hired) based semi-randomly on the wealth of the patch the turtle is on.
::::: - The wealth of the patch and turtle -> if the turtle is employed, it gains wealth and also generates a little wealth for the patch; If unemployed, it drains the wealth of the patch a little and its wealth decreases a little.
::::: - Based on the suicide rates, employment and wealth, it will also semi-randomly decide if the person is likely to kill themselves.
:::: That way we can at least simulate and see the wealth distribution, suicide rates and population distribution in a very simplified model... Does that makes sense or am I still in over my head? :) [[User:Xkaij00|Xkaij00]] ([[User talk:Xkaij00|talk]]) 19:20, 21 December 2018 (CET)

Topic/goal: '''Comparing the efficiency of Diamond interchange and Diverging diamond interchange'''

'''Definition of the problem:''' 
- [https://en.wikipedia.org/wiki/Diverging_diamond_interchange Diverging diamond interchange] is an alternative to Diamond interchange that is being used in France since 1970s and was brought to light recently (2009) in USA because it should be more effective than Diamond interchange in terms of waiting times and also in terms of safety (fewer crossing points of traffic). 
- Goal of the simulation is to measure if the statement about lower waiting times is correct and under which conditions (traffic load, traffic lights setup). 
- Throughput and waiting times will be measured under several traffic conditions, for example: most cars exiting highway are heading south or most cars entering highway are heading west, etc. 
- Model does not include simulation of traffic accidents, so the safety cannot be measured and will not be part of the simulation.

Topic/goal: '''Traffic simulation Argentinska street'''

'''Situation:''' 
- Argentinska street is one of the important roads in Prague that connects Bubenské nábřeží with bridge “Barikádníků”. It leads from city centre and other parts of city outside to the northern part of the country, and to Germany or Poland. Moreover, Argentinska street connects hospital “Na Bulovce” with city centre and other parts. For emergency vehicles it is the way how to get faster, where help is needed.

'''Definition of the problem:''' 
- There is traffic on the road during mornings and evenings, which makes people wait sometimes hours to get out and more important it makes difficult pass for emergency vehicles.

'''Purpose of simulation:''' 
In the scope is part of Argentinska street from Bubenské nábřeží till Dělnická street plus street Za Viaduktem, part of Jateční and part of Tusarova street as they have influence on the whole situation of Argentinska traffic. The purpose of the simulation is to find ways how to make traffic less. In order to do it will be checked, first, if it is possible to change lights more efficiently for cars flow. Second, answer the question – if we can add only one line only to one direction, which direction we have to choose: to city centre or from city centre?

'''Simulation environment''': Simprocess; SUMO (for traffic representation)

'''Brief process of simulation :''' 
1) Data collection. Data will be collected manually (observation) and from HERE traffic API. Manually for morning, midday and evening during 30 mins each part of the day within one week. At the end of data collecting the average distribution will be made based on the data.
2) Real situation simulation
3) Based on simulation of real situation will be checked the efficiency of lights changes
4) The hypothetical model of adding one more line will be created based on simulation of real situation
5) Summary

: Ok, SUMO could be used for this. I just don't understand what you will simulate in SUMO, and what you will simulate in Simprocess, and why? The combination of two tools is uneasy, so there should be a good reason. However sounds interesting. [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 18:41, 21 December 2018 (CET)
: The Simprocess will be used for problem solution and SUMO for traffic representation of ready solution. Because SUMO does not have strong performance in searching solution, but very good for clear representation of ready result. Combination of two tools will be useful for this case.

Topic/goal: '''Survival of the apocalypse'''

'''Definition of the problem:''' 
- This simulation would aim to showcase in what conditions can humanity survive in the zombie-apocalyptic scenario. 

The usual scenario in which zombie appears is very simple: there are some number of patiants zero and the rules
for spreading the plague is to get bitten by the infected. There is also a percantual chance of beeing immune against
the plague. Zombies are usually slower than human beeings and behave on the basic of their nearest vision.

Numerous factors can be acounted for survival, like ability for humanity to reproduce, their number, immunity,
effectivnes of the plague.

Topic/goal: '''Medieval Battle Simulation'''

'''Definition of the problem:''' 

Two kingdoms come to a dispute and after extensive diplomacy had failed, they take up arms and go to battle. 
Each kingdom can have different number of units, but they each choose from the same kind of units (unit types are better against some and weaker to other). 
Each side has their own staging area, but within that area the units can spawn at random locations to test different strategic formations. 
When they meet in battle, they fight to the last man who wins the dispute for his king.

'''Purpose of simulation:''' 
It simulates medieval combat on battlefield between two sides. 
The user can select which type of units and how many will each kingdom have. 
Repeated simulation can lead to conclusions on what strategy the kings should focus on and which units they should train for successful reign when facing a violent foe.

'''Simulation environment:''' NetLogo

: I would narrow this down to testing battle strategies. Forget kingdoms. You can perform a research on some historical strategies, their pros and cons, choose some, and try to simulate them, and compare. If it sounds meaningful, please, redefine the assignment.

:: The part about kingdoms was more of a story telling. The objects in NetLogo would just be the units (of different types).

Topic/goal: '''Proof of a business plan - simulation of capacities of a Café'''

'''Definition of the problem:''' 

At the moment we have a venue in a small town under construction which we would like to turn into a café. 
The spatial dispositions are set and now there are many questions like: how to set up tables, find out how many people can be at one time in the café, if the café is profitable when the amount of people coming in is low/medium/high, etc. 

'''Purpose of simulation:''' 
As said, I would like to simulate a process of people coming in to find out the right amount of seats and tables when knowing there will be just one staff member at the time. 
I would also like to find out whether it is even possible to manage the whole place being just one person responsible for everything and/or whether it is cost efficient. 
 
The output data should help us find out whether the whole concept is viable and based on the findings we could adjust the business plan.

'''Simulation environment:''' I would like to use Simprocess for the simulation of the venue setting and probably complement it with some calculations in Excel.

: I like the idea, just hesitate about the tool. As far as I understand, a substantial part of the whole thing is about the spatial arrangement of the café. Then Simprocess is not the first choice. Why do you want to use it? [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 18:56, 21 December 2018 (CET)

::I liked that Simprocess allowed me to work with resources. And I see the tables and chairs as a resource, as well as the working power. If the flow of people coming in is well set up, I thought, by adjusting the resources, it should be possible to find out the optional setting. Do you propose any other tool to do that? I will be greatful for other ideas to improve the solution as it is a real problem we would like to solve. [[User:Xsmyt00|Xsmyt00]] ([[User talk:Xsmyt00|talk]]) 10:21, 27 December 2018 (CET)

::: If you need to deal with spatial factors, NetLogo is definitely a better choice. If you omit the spatial characteristics, the simulation become trivial, what would not be enough for this paper. [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 02:06, 31 December 2018 (CET)

:::: Ok, I can do the simulation in NetLogo and mind the spatial characteristics. I just thought the original idea was complex enought as it would put together several rather simple simulations and tasks - like finding out the right amount of visitors based on data from people that run cafés in different places (recalculating the number of visitors based on the wealthiness of the region, based on the capacity of the venue, the number of citizens and so on).
::::I believe I can go with netLogo for simulating the venue as well, although it is not completely clear now for me, how do I find out the right ammount of seats for example?
::::I can imagine a random movement of agents coming in taking a first not-taken seat. It can also be like the agent has a capacity (it can be group of 4 or just a pair or a single person visitor) and it could take the table/seat only in case there is enough space for the whole group. There could also be a quality parameters - like grading system for the seats - how far is it from the bar, is it near the toilet and so on. So yes, that might show that some places will be more popular then others. Also the agents might have a limit under which they dont go, like if they dont find a seat with quality high enough they will leave. Now when I am writing this down I think it might work although I still have some questions. Is this something you had in mind as well or am I on completely different track? Thanks.

Topic/goal: '''Effective class configuration a plane between Prague and Dubai'''

'''Definition of the problem:''' 

There is a new airline operating between Prague and Dubai. The want to configure their planes as effectively as possible. They have one second hand Boeing 777 (396 seats in economy class only configuration)

'''Purpose of simulation:''' 
Company wants to operate daily air route between Prague and Dubai. The company can have up to four classes - economy, economy plus, business and first. Seat in higher class takes more space, but generates more money. Prices are available from companies currently operating on this route. Demand predictions can be made based on class configurations used by companies already operating on this and similar routes (6-hours mainly holiday) destinations.

'''Simulation environment:''' I would like to use MS Excel to do Monte Carlo simulation.

:: I just wonder, where is the randomnes, as you want to just derive the configuration from the already operating competition. If it should be a simulation, you would have to have real daily data (for reasonable long period, a year minimum) for the demand for the flights (there and back) and also for the individual classes.

Topic/goal: You are what you eat

'''Definition of the problem:''' 
Most people nowadays want to hit the gym or eat healthy to get fit and at the same time take a long high quality sleep and work effectively. All the success in life and your energy comes from the food (nutrition values) you consume a day and the regime you have. The new year is knocking the door and you want to make sure that you will plan your food and regime effectively so your life is in balance.

'''Purpose of simulation:''' 
Based on the input you choose the simulation should be able to give you the expected levels of achieved energy, work efficiency and especially if you are about to get fit or you will drop down to be a couch potato.

'''Input parameters''' 
- Food consumed - listed types of food with calculated nutrition values (protein, fat, sugar, energy) 
- Time spent at gym (kardio, workout, culturist) 
- Time spent at work - type of work (manual, manager) 
- Time spent sleeping 

'''Output''' 
- Your BMI 
- Your fitness level 
- Your work focus 
- Your energy level 

'''Where I will get the data? ''' 
- My roommate is a nutrition specialist and member of huge fitness project so his advice will be the source of my dependencies between values as well as values for different types of nutrition. 
- Nutrition plans. 

'''How will I get the output?''' 
I would like to use NetLogo to be able to see both values (numbers) and also monthly progress on the display (maybe a characted running between job, eating and gym. Showing HP bar? :D).
If this kind of simulation is not suitable for NetLogo then Vensim? I have no idea how would I transfer the problem into equitations which are required.

Topic/goal: '''Optimal size of HDD for virtual Digitization server'''

Definition of the problem: 
- each day an average of 47 batches of documents is being processed by the server with average size per batch of 32 MB (calculated from customers server) 
- the number of batches changes a lot and cant be easily predicted so it will have to be taken into consideration (from sample: lowest number of batches scanned in a day is 13, the highest is 134) 
- the average size is not changing that much 
- (batch contains original scanned documents, extracted data in XML files, log files, enhanced images and searchable PDF) 
- backup images from scanning will stay on the server for 6 months (those are ''additional'' ~50 % of the batch size) 
- successfully processed batches older than 14 days are deleted every day 
- for precaution lets say around 5% of batches wont be processed correctly 
- those will stay on the server and will be processed every month by admins 

Simulation environment: Vensim

:::: I would base the simulation on how much one person interacts with others, depending on this variable the person would have some probability of getting sick thus the number of ill people would increase thus the probability of him getting sick would be higher and higher.

Topic: '''Social and economical effects of reunification of North & South Korea''' 
'''Definition of the problem:''' 
Let's hope one day South and North Korea will be reunited. That would mean a big fluctuation of people between the two separated states: 
- North Koreans will migrate to South Korea area, look for flats, try to get jobs and receive welfare. 
- South Koreans will invest in North Korea area and create jobs and factories there. 
''I would like to simulate:'' 
- What will be the population ratio of the two areas per square meter. 
- How many North Koreans will move to South Korea area after the reunification and how many of them will be on welfare and how much that will cost the new reunited country. 
- How much will the suicide rate change in Korea after the reunification since it's a known fact that defected North Koreans have a high suicide rate due to the fact they have difficulties to adjust to the new lifestyle and process propaganda-free information. 
- What will be the housing situation after the reunification. 
- How will the GDP of the new country possibly develop. 
- Possibly how much money will be needed from international help.

:::: - The turtles representing Koreans will have initial wealth (also based on the initial GDP) and they will be migrating towards one of the two states based on their inclination to migrate to the other country. This inclination will be calculated randomly based on the East-West Germany migration data and their wealth.
:::: - On each tick, the simulation will determine:
::::: - if the turtle (Korean) has a job (landed one, got fired, is working, or didn't get hired) based semi-randomly on the wealth of the patch the turtle is on.
::::: - The wealth of the patch and turtle -> if the turtle is employed, it gains wealth and also generates a little wealth for the patch; If unemployed, it drains the wealth of the patch a little and its wealth decreases a little.
::::: - Based on the suicide rates, employment and wealth, it will also semi-randomly decide if the person is likely to kill themselves.

Topic/goal: '''Comparing the efficiency of Diamond interchange and Diverging diamond interchange'''

'''Definition of the problem:''' 
- [https://en.wikipedia.org/wiki/Diverging_diamond_interchange Diverging diamond interchange] is an alternative to Diamond interchange that is being used in France since 1970s and was brought to light recently (2009) in USA because it should be more effective than Diamond interchange in terms of waiting times and also in terms of safety (fewer crossing points of traffic). 
- Goal of the simulation is to measure if the statement about lower waiting times is correct and under which conditions (traffic load, traffic lights setup). 
- Throughput and waiting times will be measured under several traffic conditions, for example: most cars exiting highway are heading south or most cars entering highway are heading west, etc. 
- Model does not include simulation of traffic accidents, so the safety cannot be measured and will not be part of the simulation.

Topic/goal: '''Traffic simulation Argentinska street'''

'''Situation:''' 
- Argentinska street is one of the important roads in Prague that connects Bubenské nábřeží with bridge “Barikádníků”. It leads from city centre and other parts of city outside to the northern part of the country, and to Germany or Poland. Moreover, Argentinska street connects hospital “Na Bulovce” with city centre and other parts. For emergency vehicles it is the way how to get faster, where help is needed.

'''Definition of the problem:''' 
- There is traffic on the road during mornings and evenings, which makes people wait sometimes hours to get out and more important it makes difficult pass for emergency vehicles.

'''Purpose of simulation:''' 
In the scope is part of Argentinska street from Bubenské nábřeží till Dělnická street plus street Za Viaduktem, part of Jateční and part of Tusarova street as they have influence on the whole situation of Argentinska traffic. The purpose of the simulation is to find ways how to make traffic less. In order to do it will be checked, first, if it is possible to change lights more efficiently for cars flow. Second, answer the question – if we can add only one line only to one direction, which direction we have to choose: to city centre or from city centre?

3) Based on simulation of real situation will be checked the efficiency of lights changes
4) The hypothetical model of adding one more line will be created based on simulation of real situation

(gif representing the mold [[https://www.reddit.com/r/gifs/comments/a1geie/slime_mold_searching_for_food/|here]] ) I should be able to confront that with a reality and the number of “foods” and speed of the mold could be variable.

Topic/goal: '''Medieval Battle Simulation'''

'''Definition of the problem:''' 

Two kingdoms come to a dispute and after extensive diplomacy had failed, they take up arms and go to battle. 
Each kingdom can have different number of units, but they each choose from the same kind of units (unit types are better against some and weaker to other). 
Each side has their own staging area, but within that area the units can spawn at random locations to test different strategic formations. 
When they meet in battle, they fight to the last man who wins the dispute for his king.

'''Purpose of simulation:''' 
It simulates medieval combat on battlefield between two sides. 
The user can select which type of units and how many will each kingdom have. 
Repeated simulation can lead to conclusions on what strategy the kings should focus on and which units they should train for successful reign when facing a violent foe.

'''Simulation environment:''' NetLogo

: I would narrow this down to testing battle strategies. Forget kingdoms. You can perform a research on some historical strategies, their pros and cons, choose some, and try to simulate them, and compare. If it sounds meaningful, please, redefine the assignment. [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 18:48, 21 December 2018 (CET)

:: The part about kingdoms was more of a story telling. The objects in NetLogo would just be the units (of different types). I envisioned them to spawn at random on their given side of the plane, but if it's necessary I could include spawning in historical formations. Would that be ok?

Topic/goal: '''Proof of a business plan - simulation of capacities of a Café'''

'''Definition of the problem:''' 

At the moment we have a venue in a small town under construction which we would like to turn into a café. 
The spatial dispositions are set and now there are many questions like: how to set up tables, find out how many people can be at one time in the café, if the café is profitable when the amount of people coming in is low/medium/high, etc. 

'''Purpose of simulation:''' 
As said, I would like to simulate a process of people coming in to find out the right amount of seats and tables when knowing there will be just one staff member at the time. 
I would also like to find out whether it is even possible to manage the whole place being just one person responsible for everything and/or whether it is cost efficient. 
 
The output data should help us find out whether the whole concept is viable and based on the findings we could adjust the business plan.

'''Simulation environment:''' I would like to use Simprocess for the simulation of the venue setting and probably complement it with some calculations in Excel.

: I like the idea, just hesitate about the tool. As far as I understand, a substantial part of the whole thing is about the spatial arrangement of the café. Then Simprocess is not the first choice. Why do you want to use it? [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 18:56, 21 December 2018 (CET)

::I liked that Simprocess allowed me to work with resources. And I see the tables and chairs as a resource, as well as the working power. If the flow of people coming in is well set up, I thought, by adjusting the resources, it should be possible to find out the optional setting. Do you propose any other tool to do that? I will be greatful for other ideas to improve the solution as it is a real problem we would like to solve. [[User:Xsmyt00|Xsmyt00]] ([[User talk:Xsmyt00|talk]]) 10:21, 27 December 2018 (CET)

Topic/goal: '''Effective class configuration a plane between Prague and Dubai'''

'''Definition of the problem:''' 

There is a new airline operating between Prague and Dubai. The want to configure their planes as effectively as possible. They have one second hand Boeing 777 (396 seats in economy class only configuration)

'''Purpose of simulation:''' 
Company wants to operate daily air route between Prague and Dubai. The company can have up to four classes - economy, economy plus, business and first. Seat in higher class takes more space, but generates more money. Prices are available from companies currently operating on this route. Demand predictions can be made based on class configurations used by companies already operating on this and similar routes (6-hours mainly holiday) destinations.

'''Simulation environment:''' I would like to use MS Excel to do Monte Carlo simulation.

:: I just wonder, where is the randomnes, as you want to just derive the configuration from the already operating competition. If it should be a simulation, you would have to have real daily data (for reasonable long period, a year minimum) for the demand for the flights (there and back) and also for the individual classes. Only then you are able to derive probability distributions for the simulation that would make sense. [[User:Oleg.Svatos|Oleg.Svatos]] ([[User talk:Oleg.Svatos|talk]]) 22:31, 21 December 2018 (CET)

Topic/goal: You are what you eat

'''Definition of the problem:''' 
Most people nowadays want to hit the gym or eat healthy to get fit and at the same time take a long high quality sleep and work effectively. All the success in life and your energy comes from the food (nutrition values) you consume a day and the regime you have. The new year is knocking the door and you want to make sure that you will plan your food and regime effectively so your life is in balance.

'''Purpose of simulation:''' 
Based on the input you choose the simulation should be able to give you the expected levels of achieved energy, work efficiency and especially if you are about to get fit or you will drop down to be a couch potato.

'''Input parameters''' 
- Food consumed - listed types of food with calculated nutrition values (protein, fat, sugar, energy) 
- Time spent at gym (kardio, workout, culturist) 
- Time spent at work - type of work (manual, manager) 
- Time spent sleeping 

'''Output''' 
- Your BMI 
- Your fitness level 
- Your work focus 
- Your energy level 

'''Where I will get the data? ''' 
- My roommate is a nutrition specialist and member of huge fitness project so his advice will be the source of my dependencies between values as well as values for different types of nutrition. 
- Nutrition plans. 

'''How will I get the output?''' 
I would like to use NetLogo to be able to see both values (numbers) and also monthly progress on the display (maybe a characted running between job, eating and gym. Showing HP bar? :D).
If this kind of simulation is not suitable for NetLogo then Vensim? I have no idea how would I transfer the problem into equitations which are required.

:: You got it right - it is Vensim topic without any doubt. Without mathematical formulation you can not do any simulation, so you have to deal with mathematical model formulation anyway.So, if Vensim is ok with you, than we can approve it.

:::: Then I will go with Vensim and try to put together something meaningful! [[User:Jan.pippal|Jan Pippal]]
:::::: OK. Then '''approved'''. [[User:Oleg.Svatos|Oleg.Svatos]] ([[User talk:Oleg.Svatos|talk]]) 12:29, 24 December 2018 (CET)
