Genetic and memetic algorithms for scheduling railway maintenance activities
Nowadays railway companies are confronted with high infrastructure maintenance costs. Therefore good strategies are needed to carry out these maintenance activities in a most cost effective way. In this paper we solve the preventive maintenance scheduling problem (PMSP) using genetic algorithms, memetic algorithms and a two-phase heuristic based on opportunities. The aim of the PMSP is to sched...
متن کاملA heuristic approach to railway track maintenance scheduling
Travelling safely and comfortably on high speed railway lines requires excellent conditions of the whole railway infrastructure in general and of the railway track geometry in particular. The maintenance process required to achieve such excellent conditions is largely complex and expensive, demanding an increased amount of both human and technical resources. In this framework, an optimal schedu...

متن کاملOptimal Scheduling of Connections in Railway Systems
Complex railway networks typically consist of widely diffused OD-pairs by which it is impossible to provide direct trips only. Therefore, passengers often have to change trains at transfer stations. Guaranteeing scheduled connections is complicated by delays during operation. To improve and maintain the quality of transfers requires optimal scheduling and control of connections at transfer stat...
متن کاملHeuristic based track maintenance scheduling optimisation
The maintenance of railway track is highly relevant for the service quality and safety. This task demands huge technical and human resources. Therefore an optimal deployment of the available resources is crusial for the cost-effectiveness of railway operation. Furthermore, the track geometry maintenance activities need to be planned up to two years in advance. For this reason the French railway...
