High Level Petri Nets Model for Course Scheduling in Higher Education Institutes: Case Study Tehran Institute of Technology (Mojtame Fanni Tehran)

The course scheduling problem is one of common problems in the research topics, there are many methods for designing and modelling these problems. In this research the researchers used the high-level petri nets (HLPN) as a modelling and visualizing method; the HLPN methods are powerful and easy applicable methods for modelling, visualizing and simulation the concurrent and complex systems. This research based on case study from the Tehran Institute of Technology (mojtame Fanni Tehran) located in Tehran, Iran. The problem contains three classes, three instructors and eighty students that held in three periods, duration of every period is 120 minutes and the breaktime duration is 15 minutes. The distribution of students, instructors through the classes in three periods make the course scheduling problem complicated and using the Colored Timed petri net (CTPN) as a part of High-Level Petri Net method help the researcher to model and schedule the course scheduling problem effectively. The mathematical-graphical property of the HLPN make this method more advantages in model these systems. In the future the researchers can model these kinds of problems with stochastic and fuzzy behaviors.
