论文摘要
由于铁路使用的增加，铁路场和维护地点的容量已成为容纳现有滚动库存的局限性。为了减少夜间维护地点的容量问题，铁路企业考虑执行更多的白天维护，但是在需要驻扎的位置进行白天维护的选择并不直接。除其他外，这取决于计划的滚动库存流通和需要执行的维护活动。本文提出了维护位置选择问题（MLCP），并为此问题提供了混合整数线性编程模型。该模型表明，对于来自荷兰铁路的代表性滚动库存流通，可以在白天进行大量维护活动。同样，这表明该模型提供的位置选择在不同的时间范围内和滚动库存循环下都很稳健。此外，为了计划目的而言，认为优化模型的运行时间被认为是可以接受的。
Due to increasing railway use, the capacity at railway yards and maintenance locations is becoming limiting to accommodate existing rolling stock. To reduce capacity issues at maintenance locations during nighttime, railway undertakings consider performing more daytime maintenance, but the choice at which locations personnel needs to be stationed for daytime maintenance is not straightforward. Among other things, it depends on the planned rolling stock circulation and the maintenance activities that need to be performed. This paper presents the Maintenance Location Choice Problem (MLCP) and provides a Mixed Integer Linear Programming model for this problem. The model demonstrates that for a representative rolling stock circulation from the Dutch railways a substantial amount of maintenance activities can be performed during daytime. Also, it is shown that the location choice delivered by the model is robust under various time horizons and rolling stock circulations. Moreover, the running time for optimizing the model is considered acceptable for planning purposes.
