基于突发故障的高速列车运行调整研究

摘要

区间突发故障下的运行图调整是高速铁路运输组织调整优化的重要内容.在区间故障临时不能行车的情况下,受影响的列车不能按原计划运行.因此,高铁调度员需要快速调整列车到发时刻和顺序,减少故障对后续时段内列车运行的影响.本文建立混合整数线性规划模型,模型中详细讨论了故障发生时区间运行列车的停车问题,并利用CPLEX软件进行求解.本模型可快速求解中小型规模问题,大规模问题则分阶段进行求解.最后,以武广高铁为背景构建算例,求解各故障情况下的列车运行调整方案.%Trains rescheduling is a critical task for high-speed railway dispatching during unexpected disruption. When segment blockage occurs, the affected trains cannot run as planned, and a quick rescheduling decision has to be made to minimize the influence of the disruption. In this paper, the train rescheduling problem is formulated as a MILP model. The stopping patterns of trains that are affected by the disruption are explicitly handled. The model is solved using CPLEX. It is found that the model performs well for small-scale problems. For large-scale problems, however, the problem needs to be divided into several stages. The proposed method is tested using real data from Wuhan-Guangzhou high-speed railway. The results show that method can be efficiently used for rescheduling during different disruptive situations.
