Assignments WS 2018/2019
 | Please, put here your assignments. Do not forget to sign them. You can use ~~~~ (four tildas) for an automatic signature. Use Show preview in order to check the result before your final sumbition. |
| Please, strive to formulate your assignment carefully. We expect an adequate effort to formulate the assignment as it is your semestral paper. Do not forget that your main goal is a research paper. It means your simulation model must generate the results that are specific, measurable and verifiable. Think twice how you will develop your model, which entities you will use, draw a model diagram, consider what you will measure. No sooner than when you have a good idea about the model, submit your assignment. And of course, read How to deal with the simulation assignment. |
| Topics on gambling, cards, etc. are not welcome. |
 | In order to avoid possible confusion, please, check if you have added approved in bold somewhere in our comment under your submission. If there is no approved, it means the assignment was not approved yet. |

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.

- 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.
Simulation environment: Netlogo
