Simulation proposal (dolj04)

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

on what data you will base the simulation? I do not see any causal loops in the issue you are trying to solve, using Vesim does not make much sense then- this topic suits the Monte Carlo if you have the data to derive the parameters from. Oleg.Svatos (talk) 22:38, 18 December 2018 (CET)

Topic: likelihood of infection with flu

Definition of the problem:
- everyone has a certain probability of getting sick with a flu, this model calculates the probability based on the people you are in contact with (two types of people, infected, not infected). Other variables and levels are available (e.g. infestation, total population

Simulation environment: Vensim

on what data you would set up the simulation? how would you simulate the individual people and their connection in Vensim? (in my opinon this topic fits multiagent simulation) Oleg.Svatos (talk) 22:30, 18 December 2018 (CET)
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. The variable infestation would represent how much the illness is easily transimited to other people. Martin svejda (talk) 14:04, 19 December 2018 (CET)
I do not see it as simulation - not much of randomness, no causal feedback loops and pretty obvious result (the longer the simulation would run, the more sick people or that one gets sick) with no practical use. Not to mention, there is no data to derive the equations needed. Either reformulate it for the Netlogo so that it has some useful results based on some real data, or try something else. Oleg.Svatos (talk) 14:27, 19 December 2018 (CET)
Ok, I will try something else. New proposal at the bottom of the page Martin svejda (talk) 16:46, 19 December 2018 (CET)

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.

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

Definition of the problem:
- 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: Maze runner vs fire

Definition of the problem:
- There will be a maze, in one corner a person, who tries to find the way out, in the other corner will be fire spreading rapidly. Does the person survives or dies by fire? Person and fire wont be able to jump through walls.

Topic/goal: Traffic simulation Argentinska street

- 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

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.
