摘要:

大型高速铁路客运站常狗万要实名制衔接多条高速铁路线路,其车站作业需要考虑多方向列车的到发线合理安排与进路冲突疏解。当车站作业受到干扰时,快速制定合理的到发线运用调整方案,对于保障所衔接各线路上列车的正常运行具有重要作用。大型高铁客运站到发线运用调整问题的决策需要满足实时性、可执行性和安全性要求。在考虑到发线与咽喉区进路综合运用优化的前提下,以列车运行晚点和车站作业秩序影响双方面最小化为目标,建立了混合整数线性规划模型。将该问题分解为到发线运用方案编制子问题和列车到发时刻调整子问题,并设计了基于分支定界的算法框架。在12条到发线、84列列车的算例实验中耗时1.33 s获得测试干扰场景下的最佳调整方案,验证了模型及算法的有效性。

Large high-speed railway station connecting multiple high-speed railways needs reasonable arrangement of platforms for multi-direction trains and is required to ease the route conflicts in the operation. Making reasonable train platform rescheduling instantly after interference to station operation guarantees train operation order on the connected high-speed rails. The decision-making of train platform scheme rescheduling needs to meet the requirements of real-time, executability and safety. Under the premise of integrated optimization of platforms and routes in the throat, in order to minimize the impact of train delay and station operation, the mixed integer linear programming model was established, where the problem was decomposed into two sub-problems: the train platform allocation problem and the arrival and departure time rescheduling problem, and the algorithm framework based on branch and bound algorithm was designed. The best adjustment was obtained in the test experiment of 12 arrival and departure tracks and 84 trains under the interference scenario, which further verifies the validity of the model and the algorithm.
