Simulation of north korea migration

2019-01-21T18:24:59Z

Xkaij00:

= Introduction =

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 and also cast a variety of problems. That is a very interesting situation we could simulate.

=Problem definition=

The aim of this simulation is to determine some key factors and their changes after the border between the two countries opens.

We are interested especially in:
* the migration rate from North to South Korea,
* North Koreans employment rates,
* wealth ratio between the two regions
* and suicide rates among North Koreans facing the comparison with much more developed neighbor.

=Method=

As we are dealing with people moving around an area and having attributes, that means our obvious choice should be a multi-agent simulation. For this simulation, I've chosen to use NetLogo 6.0.4.

= Model =

== Data ==

We need to have some data to start with. For the purpose of the simulation, the following data were used:

* GDP per capita of North Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/kn.html CIA.gov] ($1,700)
* GDP per capita of South Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/ks.html CIA.gov] ($37,600)
* Population of North Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/kn.html CIA.gov] (cca. 25 000 000)
* Population of South Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/ks.html CIA.gov] (cca. 51 000 000)
* Area of North Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/kn.html CIA.gov] (cca. 120 000 sq. km.)
* Area of South Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/ks.html CIA.gov] (cca. 100 000 sq. km.)
* Employment rate of North Korea from [https://www.cia.gov/library/publications/the-world-factbook/geos/kn.html CIA.gov] (cca. 75%)
* Suicide rates of North Korea from [https://www.theguardian.com/world/2014/sep/04/north-korea-suicide-rate-among-worst-world-who-report The Guardian] (9790 suicides per population)
* Labour share of GDP - from [https://www.economicshelp.org/blog/135320/economics/labour-share-of-gdp/ Economics Help] we assume it's about 50%
* Some reference migration rate to start from. As a reference, I used migration rates from Eastern to Western Germany after the fall of the Berlin wall. Based on [https://www.demographic-research.org/volumes/vol11/7/11-7.pdf this paper] I assume it's somewhere below 0.0250.

== Agents and initial states ==

=== Turtles ===

For the purpose of the simulation, we need two types of agents - South Koreans and North Koreans.

North Koreans will migrate, work, and sometimes, sadly, kill themselves. They own the following attributes with initial values:

* Wealth - randomly calculated from 50% (labour share) of GDP per capita.
* Migration inclination - randomly calculated from reference migration rate.
* Employment status - boolean randomly determined from initial employment rate.
* Suicide inclination - randomly calculated from initial suicide rates.

South Koreans will sometimes invest in North Korea as there will be some opportunity to build capitalism when communism fell down. They own the following attributes with initial values:

* Is investor? - Boolean randomly calculated to be around 5% of the richest South Koreans.
* Is investing? - Boolean initially false.

=== Patches ===

The patches will be divided proportionally by area of the respective countries and will be assigned wealth based on GDP of the country (random less than countries GDP).

The patches are also assigned with rentability which is deliberately set to around 1% for North Korea and 3% for South Korea. Rentability is then used to calculate wealth movement.

== Simulation Mechanism ==

* On each tick the simulation modifies attributes of turtles and patches:
** randomly based on patch wealth if the North Korean is employed
** based on the employment status, it changes the wealth of the patch and of the North Korean
** based on the employment status, wealth and initial suicide rates, it determines if the North Korean will commit suicide (if he does, he's reborn)
** based on neighbouring turtles of a South Korean investor in North Korea it will increase the wealth of his patch
* On each tick, it will also determine:
** If the North Korean will migrate based on his migration inclination and his wealth ratio
** If a South Korean investor decides to invest in North Korea
* Then it will move the agents that are determined to be moved.

The respective code looks like the following:

to go
manipulate-resources
move
tick
if ticks >= 250 [stop]
end

to manipulate-resources

;; North Koreans
ask north-koreans [

;; determine employment status - the richer the patch is, the better chance to be employed
set employed random-float 1 < patch-wealth / (sum [patch-wealth] of nk-patches / nk-patches-count)

let suicidal false

ifelse employed
[
let wealthIncrease random-float (patch-wealth * patch-rentability) ;; wealth increase for employed person
set turtle-wealth turtle-wealth + wealthIncrease
set patch-wealth patch-wealth + random (wealthIncrease / 2) ;; increase patch wealth with 50% added value
ifelse turtle-wealth > 0 [
set suicidal random-float 1 < random-float (suicide-inclination / nk-wealth-ratio) ;; has some wealth, let's determine if suicidal based on inclination and wealth ratio
]
[
set suicidal random-float 1 < random-float (suicide-inclination * 1.5) ;; totally broke, very big chance of suicide (but employed so less than if unemployed)
]
]
[
let wealthDrain random-float (patch-wealth * (patch-rentability / 2)) ;; wealth drain for employed person (50% of rentability)
set turtle-wealth turtle-wealth - wealthDrain
set patch-wealth patch-wealth - (wealthDrain / 2) ;; decrease patch wealth with half of the person drain (subsidies for the person)
ifelse turtle-wealth > 0 [
set suicidal random-float 1 < random-float ((suicide-inclination + suicide-inclination * 0.75) / nk-wealth-ratio) ;; suicide inclination increases by 75% if unemployed
]
[
set suicidal random-float 1 < random-float (suicide-inclination * 2) ;; totally broke and unemployed, very big chance of suicide
]
]

if suicidal [
set nk-suicides nk-suicides + 1
;; rebith turtle (so we keep the same amount of turtles)
set-nk-init-turtle-vars
]

]

;; South Koreans (investors)
ask south-koreans [
if is-investor and is-investing [
set patch-wealth patch-wealth + (random-float 1.88 * (count turtles-here + count turtles-on neighbors)) ;; up to 50% of GDP per capita of SK (assuming wage share of 50%)
]
]

end

to move
ask north-koreans
[
;; determine if prone to migration based on turtle's inclination to migrate and its wealth ratio
if random-float 1 < turtle-migration / nk-wealth-ratio
[
Move-to one-of patches with [pcolor = 109] ;; migrate to South Korea
]
]
ask south-koreans
[
;; determine if prone to migration based on turtle's wealth and potential to invest
if is-investor
[
set is-investing true
Move-to one-of patches with [pcolor = 19] ;; migrate to North Korea to invest
]
]
end

== Simulation Outputs ==

The simulation shows:

* A chart of outmigration rate.
* Unemployment rate among North Koreans.
* Suicide rate among North Koreans.
* Wealth ratio between North and South Korea.

=Results=

* The simulation run for 250 ticks consistently results in around 10% - 12% unemployment rate amongst North Koreans.
** That is a value that could be realistic.
* The outmigration rate from North Korea stabilizes itself on approx. 0.3%, rising more steeply in the beginning.
** This value also looks realistic and means that some North Koreans will migrate to South Korea but not (almost) everyone.
* The suicide rate amongst North Koreans sadly comes to approx. 4%.
** This value is quite alarming and let's hope that the model is wrong in this particular part.
* The ratio between North and South Korea wealth increases very slightly from initial 2.71% to 2.73%.
** Also here, the result is questionable and would probably call for re-evaluation of the formulas, since the growth of wealth seems very very slow.

=Conclusion=

If we are to trust the designed model, the main concern will be a huge suicide rate amongst North Koreans and very slow growth of North Korea wealth relative to South Korea.

The migration and unemployment rates, however, seem quite moderate and realistic.

The model simplifies a very complex issue and assumes some deliberate facts and measures, therefore it might not be very accurate. Despite that, I think that it could be a good start for future work and by extending the model and making it more precise, we could, to an extent, capture a quite realistic scenario what would happen after the reunification of the two Koreas.

== 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 

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.

What agents would you use, what parameters, how the simulation would look like, on what data it should be based (and where you get them). And perhaps focus on fewer goals.

::: The relevance of comparison with Germany is questionable, but, ok. Let's say there perhaps isn't any better comparison. Nevertheless, I still don't understand, how the simulation should work. How the agents will act? How it will be measured? How you will be able to calculate all the figures? [[User:Tomáš|Tomáš]] ([[User talk:Tomáš|talk]]) 18:28, 21 December 2018 (CET)

:::: 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)

::::: To be honest, I am a bit skeptical about the results. As the assignment is based on vague assumptions, I think the results will be very general.

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.

'''Simulation environment''': Netlogo

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)

::: 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. 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.
