综合维修天窗与列车开行方案的协同优化研究

在提速后的铁路繁忙干线上,旅客列车开行方案比较复杂,需要兼顾包括天窗设置在内的多方面因素.在区段内考虑综合维修天窗与旅客列车的协调主要是优化两者之间的时间关系.运用同余思想分析旅客列车的合理开车范围.通过建立维修天窗与列车开行方案之间的协调优化关系模型,得出理论上的最佳天窗时段就是使概率频数最小的列车合理开车时间段.

Study on Collaboratively Optimizing the Coordination Between Train Running Schedule and the Comprehensive Maintenance Gap

On the busy trunk lines after speeding-up, the running schedule of passenger trains is complex, so multi-aspect factors including the setup of maintenance gap, should be considered. The key point on the coordination between comprehensive maintenance gap and operation of passenger trains in operation sections is to optimize the time relationship of each other. The paper analyzes the reasonable operation time of passenger train by using congruence theory. Through establishing the collaborative optimizing relation model between maintenance gap and train running schedule, the best maintenance gap period is received on theory, which is the train reasonable operation time with least probability frequency.
