## Simulation Proposal (xvatj00)

Software: Vensim

I am a contemporary gospel choir conductor (choir and full professional band). We organize more or less 3 concerts a year. It has been a long time since we released our last CD and now we would like to earn money to be able to start recording a new one. For this purpose, I would like to find out those factors (such as choir performance, band performance, tickets’ price, concert’s location, etc.) that influence potential audience when choosing a band to go see and how to improve them, and thus get more people to come to our concerts - and earn more money for the tickets and in general. I will use a survey to get data about people’s preferences. Xvatj00 (talk) 17:45, 27 November 2017 (CET)

For this kind of simulation you would need ritch historical data so that you would be able to find premises you would then build the equations on (and to be able to verify the model when you compare its results with the historical data). Unfortunately the survey will not help you to quantify the parameters and the number of concerts is really low to be usable for such simulation. I probabbly would suggest a different topic.

I can get data up to 10 years back. The number of concerts included only those concert that are organized by us only, but we perform in many other concerts as well. Do you have any suggestions how to make the simulation possible? Thank you. Xvatj00 (talk) 18:59, 30 November 2017 (CET)
You would have to be able to define parameters that determine the demand for the individual concerts, and based on the data quantify them and quantify their impact on the demand for a concert. Based on that one could then discuss how the concert and its content should be se up so that you get maximum profit out of it. That is not a really easy ...Oleg.Svatos (talk) 15:07, 6 December 2017 (CET)

### Intersection Optimalization (NEW ASSIGNMENT)

Software: NetLogo

Almost every day, I walk by the intersection of Anglická and Bělehradská / Škrétova. During peak hours, there are traffic jams on only one street leading to the intersection, which I find interesting. Because of this fact, I would like to simulate the intersection in order to find out if the lights are really optimally set there, and potentially, find out the optimal setting of the intersection’s lights.

As I’ve already mentioned, there are lights directing the intersection. Also, there is a tram track on the Bělehradská / Škrétova street which goes straight, while most of the cars coming from Bělehradská street turn left. I will use real intervals of all of the lights from a chosen time during peak hours, and the number of cars and trams coming to the intersection (including their speed, direction, etc.). At first, I will set the lights to constant ticks according to the reality to simulate the real situation. After that, I will try to find out an optimal setting of the lights and evaluate, what the optimal setting is or if it meets with the reality. Xvatj00 (talk) 18:48, 8 December 2017 (CET)

Please, try to obtain real data. Approved. Tomáš (talk) 04:05, 12 December 2017 (CET)

### Bars in a concert hall serving a dance event (yaua00)

Software: NetLogo

None party exists without alcohol, so let’s imagine a dance event in a concert hall Lucerna with 2 bars and in the concert hall. People during a dance event are randomly distributed along 1300 m^2. Prices are regulated by the owner of the concert hall, so they are equal for each bar. This fact means, that people choose to which bar to go considering just the distance, this also means that both should have almost the same profit.

But one greedy owner of one of the bars wants to have greater profit then the other one by moving to another position and attracting customers in such a way.

One more question of this simulation would be – what would happen if more people open their bars there (luckily the size of the hall allows it) and they bring their own prices to the concert hall, so the people can now choose not only the distance to the bar, but also the price of their favorites drinks.

What is the point of such a simulation? Tomáš (talk) 04:12, 12 December 2017 (CET)

### Social media post (Amelievh)

Software: Netlogo

Nowadays social media is a hot topic, and a lot of recruiters and other business people use linked in to attract new employees or just to share their thoughts.

For my simulation, I was thinking about researching the reach of a social media post. Someone posts something on LinkedIn, and depending on the amount of connection and amount of sharing I want to check how many people you can reach with one post. I will try to find real-world numbers and make it a useful tool for the business world.

Simulations on social media are typically problematic, mostly due to the lack of real data. I would recommend to try finding, something else. Tomáš (talk) 04:11, 12 December 2017 (CET)

## Simulation Proposal (A_V)

Software: NetLogo

We own a zoo. We have a huge kennel for hamsters. We have observed a strange behavior of the hamsters. When a female hamster gives birth to babies (usually up to 12), the mother may come under the pressure of nurturing each and everyone of them. After giving the birth a female hamster becomes weak and may die if does not have enough food and vitamins. Also when the mother is weak, she can not lactate milk for all of her babies. Since the quality of food provided by the zoo does not always satisfy the hamster, the mother eats her weakest babies to get extra protein to feed other babies, which increases the probability of survival of her and the rest babies. Another reason of the deaths of hamsters, as mentioned above, is the adequate quality of food. If the food does not satisfy the hamsters, they do not eat it and the food rots by polluting the kernel which leads to an increased number of hamster deaths. In the simulation I will focus on how much the food quality, the amount of food and keeping the kernel clean influences the number of hamster deaths.
