编组站配流相关问题分析

Analysis on the Correlated Problems of Wagon-flow Allocation in Marshalling Station

编组站配流是阶段计划中不可缺少的内容。本文以路网性编组站为研究对象,深入分析了编组站站型对车流组织的影响,着重探讨了配流计划与调机运用的关系。根据出发列车车流来源的确定性程度,将出发车流来源划分为A、B、C三类。从编组站配流问题的三个方面入手,即出发列车编组顺序的确定、出发车流来源的确定以及到达列车解体顺序的确定,利用双层规划模型描述了配流问题的优化方法。

Wagon-flowallocation in marshalling station is indispensable content in the stage planning. The influence of station layout on wagon-flow was analyzed in depth, taking the railway network marshalling station as a research object, and then the relation between the wagon-flow allocation planning and the use of the shunting was emphasized. According to the uncertainty degree of the wagon-flow source of the departure trains that can be divided into three kinds of A, B, C, and starting from the three respects, that is, the determination of the formation order of the departure trains, the departure train flow source and the untwining order of the arrival trains, the optimization method for wagon-flow allocation problem was described with a bi-level programming model.
