These are the instructions for running all the projects: = System Dynamics: For the SD model to be run you need to download the AnyLogic 7.0 or newer version from this link http://www.anylogic.com/downloads. After downloading you need to register for a academic demo usage of the program and a code will be sent to your mail. Use that code to activate the program. Then just import the model from the folder uploaded on my msdl page and run it. - Cellular Automata: The code is written in Java and in order to successfully run the CA model you need to have the latest Java version and Eclipse 4.2 or newer. The main class in the project is FluEpidemic.java and by runing it the simulator will be started. By running the ShootingClass.java the same model will be run for 100 times and a graph will be presented with the percentage of infected in each run. - Agent-based Modelling and Simulation: Download Repast Simphony 2.0 or newer from this link http://sourceforge.net/projects/repast/files/Repast%20Simphony/Repast%20Simphony%202.2/Repast-Simphony-2.2-win32.exe/download. It can be downloaded also from other places if the link is not working because the software is free. Then just import the project I have uploaded and run the project. After the appearance of the simulation window click on the play button on the top of the window.
