Spread of 19-COVID

Author : Toscool (talk) 11:32, 11 December 2020 (CET)

Simulation : I will build a dynamic model of an epidemic his the dynamic issues. I will focus on the spread of Covid-19 in a population and Specially I will try to modelize the effect of a lockdown on the number of infections and deaths. I will start with a susceptible population, with one infected people that infect 10 people with a certain probability. When you are infected you go the doctors and with a certain probability you go in the recovery population or in the hospital. Then you have a percentage of chance to die in this hospital or to recover. The lockdown will triggered when the ratio of people who where to the doctor and total population exceed a certain percentage. We lockdown and by reducing the number of people you infect in the beginning.

Goal of simulation : I aim to model the impact of a lockdown on the spread of COVID on a population. It will also show the difference between countries, for example if we lockdown too late. What will be the impact of these decisions.

Method : I will use VensimPLE for this simulation, as it is a dynamic system, and In my home university I know that I will need to use VensimPLE for a future project and course so it will help me a lot.

NFL Free Agency

Simulation : Free agency is a period of time during the off-season in the National Football League in the US (few weeks). During that period, all 32 teams in the league can sign active players that have no contract with any other team, so called free agents. The process goes as follows: at the beginning of free agency a certain amount of players become free agents due to expiring contracts. All players can play one certain position and want to receive a certain salary. While all the teams are looking for players to play a particular position and have a certain amount of money they can spend on players. Demand and supply of a specific position group influences their value. A certain supply-and-demand-factor for each position group adjusts a player's desired salary according to his position group. Players and teams get in touch when they are located next to each other. When the position needs matches the offer and a player’s salary fits the money a team offers, that player is signed by the team and disappears from free agency market. If the offer doesn’t fit the need, a player walks on to the next team. With every round/tick/signing the supply-and-demand-factor and thus the value of players in each position group change and so does the amount of money teams are able to spend on further players. Free agency ends after a distinct number of ticks or even earlier if all players are signed or teams don’t have any money left to spend.

Goal of simulation : is to find out how a player's value changes during the period of free agency. Especially interesting is, whether players that sign a new contract early in the period received higher payments or the ones signing late in the period. Maybe a certain strategy can be deducted for players depending on their initial situation (supply-and-demand-factor) in order to reach a highly-paid contract.

Method : Since I don’t know VensimPLE yet, I think I will use NetLogo, because I see some similarities between my case and the “Escape building” case we modelled recently.

It is a bit unusual, but I can see something in common rather with Market Structure than with Building Escape. Please, just elaborate it into a greater detail and specify, how exactly should your simulation work. I am not sure you have a coherent idea about the solution. But if you work this out, I don't see a problem. Admin (talk) 21:44, 11 December 2020 (CET)
