Modeling and Solving the Train Timetabling Problem

Passenger Centric Train Timetabling Problem

The aim of this paper is to analyze and to improve the current planning process of the passenger railway service in light of the recent railway market changes. In order to do so, we introduce the Passenger Centric Train Timetabling Problem. The originality of our approach is that we account for the passenger satisfaction in the design of the timetable. We consider both types of timetable(s): cy...

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...

Train Timetabling Problem for Complex Railway Systems

This paper deals with the design of timetables for complex railway systems. Rail transportation has become a rapid, clean and efficient way to transport passengers and freights. A good timetable design is crucial to ensure the quality of the services trying to improve the efficiency of the whole system. Only such a sustainable transportation system will be in accordance to the requirements of f...

Minimal Perturbation Problem in Course Timetabling

Many real-life problems are dynamic, with changes in the problem definition occurring after a solution to the initial formulation has been reached. The minimal perturbation problem incorporates these changes, along with the initial solution, as a new problem whose solution must be as close as possible to the solution of an initial problem. A new iterative forward search algorithm is proposed to...
