针对车辆段内干扰源对地铁列车运行的扰动,以列车连带晚点期望值最小为目标,确定地铁列车平峰时段的始发时刻,分配初始缓冲时间。细分连带晚点,详细描述了连带晚点传播的各种情况,建立了简单情形下地铁列车初始布点的理论模型。经分析,该模型为凸规划的约束极值问题,且证明在小干扰条件下,均衡初始布点的列车时刻表为模型的最优解。
Aiming at the disturbances of the subway train operation by the sources of interference in the train segment, the initial time of the train peak-hour of the subway train is determined, and the initial buffer time is allocated to minimize the expected value of the late-arrival of the train. Subdivision associated with late, described in detail with the late propagation of various situations, the establishment of a simple case of subway train initial distribution of the theoretical model. After analysis, the model is convexity constrained extreme value problem, and it is proved that under the condition of small disturbance, the train schedule with balanced initial distribution points is the optimal solution of the model.
