Study on Robustness of High-speed Train Working Diagram based on EMU Utilization

基于离散事件动态系统理论,将列车发车作为基本事件,运用Max-Plus Algebra方法建立列车运行图的状态动力学方程和列车晚点传播模型;设计列车次序可调整条件下晚点传播的计算流程及方法,研究状态矩阵的更新,使Max-Plus Algebra能够适用于状态矩阵改变的迭代运算;最后综合评价列车发车次序调整、设置交路接续冗余时间及动车组交路调整3种策略对列车运行图鲁棒性的影响。案例计算结果表明,合理设置交路接续冗余时间、调整列车发车次序和调整交路能够有效消减列车晚点,提高列车运行图的鲁棒性。

Based on dynamic system theory of discrete event,taking the train departure as the basic event,the status dynamic equation of train working diagram and train delay propagation model were established by using Max-Plus Algebra,the computation process and method of delay propagation under adjustable train order were designed,and the upgrading of status equation was studied as to make Max-Plus Algebra applying to the iterated operation changed by status equation.In the end,the comprehensive evaluation on influence of 3 strategies（such as adjusting train departure order,configuring connected redundancy time of route and adjusting EMU route） on robustness of train working diagram.The example computation result shows the above 3 strategies could effectively cut down train delay and increase the robustness of train working diagram.
