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.
Based on the analysis of EMU operation model, the basic concepts are defined and analyzed.Combining with the characteristics of EMU EMU, the problem of EMU utilization planning is transformed into the generation of delivery segment and the generation of two segments based on delivery segment Step solution and using the method of compact assignment algorithm and matrix combination and based on the method of using time-balanced cross-section exchange to build the cycle model of intercity railway EMU using the existing busy main line Shanghai-Nanjing line in April 2009 train operation diagram As an example, the satisfactory result is obtained, which is in line with the specific application of intercity railway EMUs.The adoption of this model and algorithm will be a good reference for the preparation of EMU operational plans.
