分组列车的组织条件要求较高且程度更复杂,但却有利于提高铁路货物运输的效率和效益。基于系统工程原理以及微观机理融合宏观机制的指导思想,采用定性分析与定量测度相结合、理论推导与仿真实验相融合的方法,系统地研究分组列车的组织特征、集结特性、组织条件和编组方案优化等问题,主要内容和结论如下。(1)分组列车车流组织特征分析。分析分组列车在编成站、换挂站和终到站的作业流程、组织条件和组织形式,并与单组列车进行对比。结果表 The requirements for organizing trains are higher and more complex, but it is beneficial to improve the efficiency and efficiency of railway freight transportation. Based on the principle of systematic engineering and the macroscopical mechanism of microscopic mechanism, the method of combining qualitative analysis with quantitative measurement and the theoretical derivation and simulation experiment are combined to systematically study the characteristics of group trains, assembly characteristics, organizational conditions and grouping schemes Optimization and other issues, the main contents and conclusions are as follows. (1) Analysis of the Organization of Train Flow in Sub-train. Analyze the operation flow, organization conditions and organization form of group trains at compiling station, changing station and final station, and compare with single train. Results table
