客运专线动车组周期性运用计划编制的研究

动车组的运用是客运专线运输组织的关键技术之一。通过分析动车组的各种运用方式,提出了动车组周期性运用的思想;并将动车组的接续运行与检修计划制定过程转化为动车组运用网络上具有较多约束条件和目标函数的TSP中旅行商的旅行问题;在此基础上构造了在考虑综合维修条件下多基地、不同型号的动车组周期性运用计划编制的数学模型,并运用计算机模拟方法对给定运行图条件下合理配置动车组套数、存车线数量及动车段设备规模等问题进行研究;同时也分析不同运行图结构及不同维修条件对动车组需求数量的影响。初步研制开发了客运专线动车组运用计划编制模拟系统软件,该系统可给出动车组运用的交路图、维修内容、地点及时间等信息,为客运专线动车组的综合运用与维修管理提供了一些有价值的研究成果。

Research on Periodicity of Motor Train Set Scheduling for Special Lines for Passenger Traffic

Motor train set scheduling is one of the key technologies in traffic operation organization for dedicated passenger lines.On the basis of analyzing the different ways of operation of motor train sets,the thought of periodicity of motor train set scheduling is put forward and connection and turnaround plans of moter train sets are transformed into the Traveling Salesman Problem(TSP) in a network which contains many constraint conditions and objective functions.A mathematical model is derived for the formulation of periodic operation plans of motor train sets of multiple-bases and different types under the conditions of comprehensive maintenance.The number of motor train sets,number of storage tracks and hostling facility capacities of the motor train set depots are simulated provided the train diagram is given.The effects of different train diagrams and maintenance conditions on the quanlities of motor train sets are studied.The software of the motor train set scheduling simulation system is developed for the dedicated passenger lines,which may present the train set circulating diagrams,and the content,time and location of maintenance.Valuable research results are provided for the multi-purpose use and maintenance management of motor train sets on special lines for passenger traffic.
