摘　　要：通过分析城市轨道交通行车组织的特点,根据对列车运行图兑现率的影响,将行车组织调整方式分为运行计划调整策略和径路变更调整策略2类。在考虑列车与列车之间和列车与车站之间的条件约束下,以恢复当日行车计划时的列车晚点总时间最小为优化目标,建立基于2类调整策略的行车组织优化控制模型,设计算法流程,利用广州地铁7号线的基础数据进行仿真实验,实验结果表明该模型具有可行性,能够为城市轨道交通行车组织提供辅助支持。Through analyzing characteristics of train operation organization of urban rail transit, according to the influence on fulfillment rate of train working diagram, the adjustment modes of train organization are divided into 2 categories including adjustment strategy of train operation scheme and adjustment strategy of route change. Considering condition restrictions between trains and between train and station, taking minimized total train delay time while resuming the sameday train operation scheme as optimization object, the optimal control model of train operation organization based on above 2 categories of adjustment strategies is established and its algorithm is designed, and then, the simulation is taken by using the basic data of Guangzhou Metro Line 7. The simulation result shows that the model is feasible and can provide auxiliary support for train operation organization of urban rail transit.
