Platform Allocation to Trains for Prague Main Staion

Abstract

In this study, we deal with a version of train platforming problem for Prague Main Station. We propose an assignment model to allocate platform tracks to trains with regard to the train timetable and operational restrictions of station. If a train departs late from the scheduled time, a delay is occurred. Delays are caused by possible conflicts. The objective of the model is to minimize the total weighted delay of trains. After solving the problem, if the objective function value is equal to zero, it means that the timetable is evaluated as robust. Total elimination of conflicts is basic presumption for quality operation in practice. To show efficiency of model implemented in GAMS, they are tested on the base of data related to the Prague main railway station. Computational results of models are presented and discussed.
