通过设计等待用时函数,衡量不同类型的等待时间比重和减少晚点到达的数量来提高客运服务质量。该方法应用到了比利时铁路网络的一小部分。在该方法的第一阶段中提到理想缓冲时间旨在当晚点时保障列车的接续。缓冲时间是根据到达列车延误分布和不同类型的等待时间的比重来设定的。在第二阶段,标准线性规划是用来构建一个完善的时刻表,这种时刻表能够合理安排列车接续,并且在任何时候都具有理想缓冲时间。能够模拟比较不同的时刻表并且优化LP时刻表。就拿比利时铁路网络来说,最终时刻表可以合理安排列车接续而且等待时间比现行的时刻表少了40%。只有当LP模型得以应用,提出的方法才能够有助于完善时刻表,甚至改善更广泛的铁路网络。
Improve passenger service by designing wait-and-wait functions, measuring different types of waiting times, and reducing the number of late arrivals. The method is applied to a small part of the Belgian railway network. The idea of an ideal buffer time in the first phase of the method is intended to guarantee the continuity of the train when it is late. The buffering time is set according to the delay of arriving train and the proportion of different types of waiting time. In the second phase, standard linear programming is used to build a comprehensive timetable that will allow for a reasonable arrangement of train connections and has an ideal buffer time at all times. Ability to simulate different timetables and optimize LP timetables. In the case of the Belgian railway network, the final schedule can make it possible to arrange train connections and wait 40% less than the current timetable. Only when the LP model is applied can the proposed method be helpful in refining the timetable and even improving the wider railway network.
