Ordering Constraints in Time Expanded Networks for Train Timetabling Problems

The task of the train timetabling problem is to find conflict free schedules for a set of trains with predefined routes in a railway network. This kind of problem has proven to be very challenging and numerous solution approaches have been proposed. One of the most successful approaches is based on time discretized network models. However, one of the major weaknesses of these models is that fra...

A Sequencing Approach for Train Timetabling

Train scheduling is a complex and time consuming task of vital importance in many countries. To schedule trains more accurately, efficiently and robustly than permitted by current techniques a novel job shop approach is proposed and implemented. Unique characteristics of train scheduling are firstly incorporated into the disjunctive graph representation of the solution. Constructive algorithms ...

A discrete-event optimization framework for mixed-speed train timetabling problem

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...
