This project was an assignment for the Discrete Event Systems class at University of Siena. You can look at the assignment and the final report for more details.
The main script is Project_menu.m - if you run it, a menu will appear that allows you to choose the result of any question (from 2 to 7).
The model (question "1") is inside the report.
For questions "3", "4", "5", "6", "7" you can also choose to look at the saved result (stored in the folder Saved_data) or to start a new simulation, setting the parameters inside the script.
