摘要

许多货运列车在计划发车时间之前或之后离开瑞典编组站。今天,如果在前面几个车站找不到冲突的列车路线,则允许偏离发车时间。这增加了列车可能延误到达目的地并导致其他列车延误的风险。我们提出了一种元启发式方法,通过添加列车路径(用于我们的货运列车)来修改时间表,并在必要时调整周围的列车路径。新增列车路径和调整现有列车路径的目的是获得较大的瓶颈鲁棒性,即与时刻表上任何其他列车的时间距离尽可能小。我们提供了非循环时刻表和异质交通的瑞典铁路路段的实验结果。我们表明,我们快速添加了列车路径,同时提高了时间表的鲁棒性。

Meta-Heuristic for inserting a robust train path in a non-cyclic timetable
ABSTRACT Many freight trains depart Swedish marshalling yards before or after their planned departure times. Today, a deviating departure time is allowed if no conflicting train path can be found a few stations ahead. This increases the risk that the train might be delayed to its destination and cause delays to other trains. We present a meta-heuristic that modifies a timetable by adding a train path (for our freight train) and, if necessary, adjusting surrounding train paths. The aim of the insertion of the additional train path and the adjustments of the existing ones is to obtain a large bottleneck robustness, that is, the largest possible minimal temporal distance to any other train in the timetable. We provide experimental results for a Swedish railway stretch with a non-cyclic timetable and heterogeneous traffic. We show that we quickly add a train path, while improving the robustness of the timetable.

期刊介绍: Transportation Planning and Technology places considerable emphasis on the interface between transportation planning and technology, economics, land use planning and policy. The Editor welcomes submissions covering, but not limited to, topics such as: • transport demand • land use forecasting • economic evaluation and its relationship to policy in both developed and developing countries • conventional and possibly unconventional future systems technology • urban and interurban transport terminals and interchanges • environmental aspects associated with transport (particularly those relating to climate change resilience and adaptation). The journal also welcomes technical papers of a more narrow focus as well as in-depth state-of-the-art papers. State-of-the-art papers should address transport topics that have a strong empirical base and contain explanatory research results that fit well with the core aims and scope of the journal.
