Reformulations for integrated planning of railway traffic and network maintenance
Tomas Lidén(tomas.liden Abstract: This paper addresses the scheduling problem of coordinating train services and network maintenance windows for a railway system. We present model reformulations, for a mixed integer linear optimization model, which give a mathematically stronger model and substantial improvements in solving performance - as demonstrated with computational experiments on a set of synthetic test instances. As a consequence, the solution times are reduced and more instances can be solved to optimality within a given time limit.
