The invention relates to a method and system for controlling train delay propagation in a railway network based on a train diagram. The method comprises the steps of distributing and valuing buffer time in a train operation plan making stage, and adjusting arrival and departure moments and sequences of trains at stations in a train operation plan execution stage, specifically including: identifying key nodes which are likely to cause delay propagation in the railway network in the train diagram, accelerated running, adjusting the train arrival and departure sequence of the trains in a station, and stopping the train to use a standby train. According to the method, the buffer time of the train diagram is reasonably set in the train operation plan making stage, the robustness of the train diagram is improved, and the arrival and departure time and sequence of the trains at the station are timely and effectively adjusted in the train operation plan execution stage, so that the train delay propagation in the railway network is effectively controlled.
本发明涉及一种基于运行图控制列车晚点在路网中传播的方法和系统。该方法包括:在列车运行计划编制阶段,进行缓冲时间的分布与取值,在列车运行计划执行阶段,调整列车在车站的到发时刻和顺序,具体包括识别运行图中易产生晚点在路网中传播的关键节点、赶点运行、调整列车在车站的接发车顺序、停运换备用车。本发明通过在列车运行计划编制阶段,合理设置运行图的缓冲时间,提高运行图的鲁棒性,在列车运行计划执行阶段,及时且有效地调整列车在车站的到发时刻和顺序,从而有效地控制列车晚点在路网中的传播。
