Railway scheduling is a complex task of rail operators that involves the generation of a conflict-free train timetable. This paper presents a discrete-event simulation-based optimization approach for solving the train timetabling problem to minimize total weighted unplanned stop time in a hybrid single and double track railway networks. The designed simulation model is used as a platform for ge...

This paper describes a reduction in the peak traction energy of mass rapid transit (MRT) railways through timetabling. We develop a mixed integer programming (MIP) model that minimizes the maximum traction energy that occurs when trains are running simultaneously. We tried two approaches. In the first approach, we use the commercial MIP solver CPLEX. In the second approach, we propose a heurist...

Automated timetables are used to schedule courses, lectures and rooms in universities by considering some constraints. Inconvenient and ineffective timetables often waste time and money. Therefore, it is important to investigate the requirements and potential needs of users. Thus, eliciting user requirements of University Timetable Management System (TMS) and their implication becomes an import...
