在列车运行受干扰条件下,如何快速有效地调整被干扰的列车,使其尽快恢复正常运行,是铁路行车组织的重要工作。本文针对高速铁路受干扰影响导致某区间在一段时间内部分丧失通过能力的情况,建立考虑动车组接续的列车运行调整混合整数线性规划模型,采用商业优化软件CPLEX对模型进行求解。以京沪高速铁路为例,基于假设的列车运行干扰场景对模型进行测试,获得各干扰场景下的列车运行调整方案。结果表明,本文方法能为高速铁路现场调度员提供在动车组运用层面仍可行的列车运行调整图,协助他们的调度决策。
Abstract：In a disrupted situation, it is critical to reschedule disrupted trains and ensure them to recover from the disruption efficiently. We consider the situation where one track in a segment of a double-track high speed railway line is blocked. A Mixed Integer Linear Programming model is formulated to solve the train rescheduling problem considering the Multiple Units connecting. The commercial software CPLEX is utilized to solve the model. Finally, Beijing-Shanghai High Speed Railway is used to test our model. The disposition timetable for each assumed disruption scenario is obtained. The results show that our approach can provide the involved railway dispatchers with a good disposition timetable in real-time. In the disposition timetable, the connecting of Multiple Units is considered as well. This is helpful to assist the dispatchers to organize trains.
