城际铁路动车组运用计划模型

Scheduling Model of Multiple Units on Intercity Railway

摘要:

在分析动车组运用模型的基础上，对有关基本概念进行了界定和解析.结合城际铁路动车组运用特征，将动车组运用计划编制问题转化为交路段生成和基于交路段生成两个问题分步求解，并使用紧凑指派算法和矩阵相结合以及基于运用时间均衡交路段互换的方法，建立城际铁路动车组运用计划周期模型.以既有繁忙干线沪宁线2009年4月列车运行图为例加以验证，得到了符合城际铁路动车组具体运用的满意结果.该模型和算法的采用将为动车组运用计划的编制起到很好的借鉴作用.

Abstract:

By analyzing the mathematics scheduling modal of Multiple Units(MU)，the paper parses concerned basic concepts dealing with the scheduling of MU.According to the character of scheduling of MU on Intercity Railway (IR),the scheduling problem is divided into two subproblems:subroutingsmaking and routingbuilding based on the subroutings.According to an algorithm combined with compact assign and matrix,and operational time strategy designed to optimize the routings in terms of balances,the paper constitutes a modal of the periodic scheduling of MU on IR,and gives an example of HuNing mainline on the foundation of latest train graph in April of 2009 to explain the new method.Results indicate the method adapts to the actual situation of IR.The use of the model and algorithm provides a good reference for scheduling MU.
