列车运休需要解决运休地点选择、运休列车确定、运休后接续列车安排、运休后旅客换乘组织及运休后动车组调配等相互作用的5个问题。以列车正常运行及临时限速运行时间、列车从车站出发时间、相邻列车间的最小运行间隔时间、列车在终到站的晚点时间和列车在始发站的接续方式为约束条件,以列车终到站总晚点时间最小为目标函数,建立列车运休问题的数学模型。利用计算机模拟的方法,根据列车当前状态反复迭代对模型进行求解。以京沪高速仿真实验系统中沪宁段为背景,对该模型进行仿真实验。结果表明,在改变原动车组交路计划的基础上,通过运休模型合理安排列车接运及接续,可以显著地提升列车运行调整的效果。
Train holiday need to address the five issues of the location of the place of departure, the determination of the departure train, the train arrangement after the departure of the train, the organization of the passenger transfer after the holiday and the deployment of the EMU after the departure of the train. The normal operation of the train and the temporary speed limit running time, the departure time of the train from the station, the minimum running interval of the adjacent train stations, the late time of the train arriving at the final train station and the connection mode of the train at the departure station are constraints, The final arrival time of the terminal point is the minimum objective function, the establishment of a mathematical model of the train when the issue of rest. Using computer simulation method, the model is solved iteratively according to the current state of the train. Taking the Shanghai-Nanjing section of Beijing-Shanghai high-speed simulation system as the background, this model is simulated. The results show that on the basis of changing the plan of the delivery of the original mopeds, the train operation adjustment can be significantly improved by reasonably arranging the delivery and connection of the trains by means of the departure models.
