摘要: 为在列车时刻表编制过程中能够基于列车差异性对列车进行差别化处理,本文首先根据各列车速度等级、必停站次数和开行效益等差异对列车进行优先级划分,进而基于列车运行时空网络,以最小化列车总旅行时间,最小化列车始发时刻与期望时刻偏差,以及最大化列车运营效益为目标,建立考虑列车优先级的列车时刻表编制模型。考虑不同优先级列车对时空网络中有向弧占用的紧迫性差异,设计考虑列车优先级的弧组合权优化策略,并以该策略为核心设计列车时刻表编制算法。最后,以北京南至南京南方向的143列列车为例验证算法的有效性。结果分析表明:相比不考虑列车差异性和只考虑标杆车的方法,本文方法使得高优先级列车旅行速度分别提高13.7km·h-1和2.1km·h-1,列车运营效益提高0.6%和3.8%,发车时间总偏移惩罚费用减少46%和27%,由此说明考虑列车属性差异能更好提高列车运行图质量。

Abstract: In order to conduct differential treatment of trains based on their differences during the process of train timetables compilation, this paper first classifies the trains into different priorities according to their speed grades, the number of mandatory stops, and operational benefits. Then, based on the train operation space-time network, a train timetables compilation model considering train priorities is established with the objectives of minimizing the total travel time of trains, minimizing the deviation between the departure time and expected time of trains, and minimizing the cost of train cancellations. Considering the differences in the urgency of occupying the directed arcs in the space-time network by trains of different priorities, an arc combination weight optimization strategy considering train priorities is designed, and a compilation algorithm for train timetables is designed with this strategy as the core. Finally, the effectiveness of the algorithm is verified by taking 143 trains from Beijing South Railway station to Nanjing South Railway station as an example. The result shows that compared with the method not considering train differences and only considering the benchmark train, the travel speed of high-priority train is increased by 13.7 km·h-1 and 2.1 km·h-1, the operational benefits are increased by 0.6% and 3.8%, and the total penalty cost from the deviation of departure time is reduced by 46% and 27%. The results prove that considering the differences among train attributes can better improve the quality of train operation diagram.
