Train Scheduling Problem - Phase I: A General Simulation Modeling Framework

One of the important problems in management of railway systems is train scheduling problem. This is the problem of determining a timetable for a set of trains that do not violate infrastructure capacities and satisfies some operational constraints. In this study, a feasible timetable generator framework for stochastic simulation modeling is developed. The objective is to obtain a feasible train timetable for all trains in the system, which includes train arrival and departure times at all visited stations and calculated average train travel time. The developed framework includes stochastic events, and can easily cope with the disturbances that occur in the railway systems, so it can be used not only for scheduling but also for rescheduling problems.The contribution here is the developed framework.
