Abstract

Many studies had been made on optimization problems related to the maintenance operation works in the railway world. In this paper, we focus on lesser-known type of these problems. Here, the maintenance is already scheduled and the infrastructure manager can only change the train timetables and the routing. This problem is not well treated in the literature. In this work, we define the problem and we present a model. Since several days are available to solve the problem, the level of abstraction of the model and the size of the considered instances let us use an exact method. We propose a Mixed Integer Linear Program minimizing the primary delays. Results on real world instances are reported.

铁路网的维修:中断和重新调度

国内外对铁路维修作业的优化问题进行了大量的研究。在本文中，我们关注的是这些问题中鲜为人知的一类。在这里，维护已经安排好了，基础设施管理人员只能更改列车时刻表和路线。这个问题在文献中没有得到很好的处理。在这项工作中，我们定义了问题并提出了一个模型。由于有几天的时间来解决问题，模型的抽象级别和所考虑的实例的大小使我们可以使用精确的方法。我们提出了一个混合整数线性规划，使初级延迟最小化。报告了真实世界实例的结果。

期刊介绍： Electronic Notes in Discrete Mathematics is a venue for the rapid electronic publication of the proceedings of conferences, of lecture notes, monographs and other similar material for which quick publication is appropriate. Organizers of conferences whose proceedings appear in Electronic Notes in Discrete Mathematics, and authors of other material appearing as a volume in the series are allowed to make hard copies of the relevant volume for limited distribution. For example, conference proceedings may be distributed to participants at the meeting, and lecture notes can be distributed to those taking a course based on the material in the volume.
