Abstract

The integrated Train Timetabling and Stop Planning (TTSP) problem calls for determining the optimal timetables for a given set of trains, while choosing, for each train, the subset of stations where it will stop. Both the timetable and the stop plan are determined based on the passenger demand, i.e. on the number of passengers travelling between an origin and a destination stations. In this work, we study the Robust TTSP (RTTSP), where passenger demand is considered to be uncertain, as it is often the case in real practice. We propose an Integer Linear Programming (ILP) model for RTTSP based on Light Robustness, an effective technique introduced in [Fischetti, M., and M. Monaci, Light robustness In: Ahuja RK, Möhring RH, Zaroliagis CD (eds) Robust and online large-scale optimization. Lecture Notes in Computer Science 5868 (2009), 61–84. Springer, Berlin Heidelberg]. We test the proposed ILP model on real-world data of the Wuhan-Guangzhou high-speed railway corridor under different demand scenarios.

不确定旅客需求下的稳健列车调度与停站规划
综合列车时刻表和停靠计划(TTSP)问题要求为给定的一组列车确定最优时刻表,同时为每列列车选择停靠的车站子集。时间表和停站计划都是根据乘客需求,即在始发站和终点站之间旅行的乘客人数来确定的。在这项工作中,我们研究了鲁棒TTSP (RTTSP),其中乘客需求被认为是不确定的,因为在实际实践中经常出现这种情况。我们提出了一种基于轻鲁棒性的RTTSP整数线性规划(ILP)模型,这是一种有效的技术,在[Fischetti, M., and M. Monaci, Light鲁棒性]中介绍:Ahuja RK, Möhring RH, Zaroliagis CD(编)鲁棒和在线大规模优化。计算机科学,2008(5),61-84。b施普林格,柏林海德堡]。在不同需求情景下,利用武广高铁走廊的实际数据对所提出的ILP模型进行了验证。

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.
