摘要
通过对铁路车流径路的描述和现行优化方法的分析,建立一种在满足运输要求的前提下,使运输费用最小的车流径路优化模型。为使目标函数尽快地趋向满意解,对车流排列序数的初始赋值方法及调整方法进行了设计。以现行“华东铁路网径路图”及运营数据为依据,进行车流径路计算,取得了满意的径路方案。
By describing the path of railway wagon flow and analyzing the current optimization method, the paper establishes a wagon flow optimization model that minimizes freight cost while satisfying the demand of transport. In order to obtain the best possible result of objective function, it designs the initial value input method for flow sequence number and its adjustment method. Taking current “Train Path Diagram of East China Railway Network” and relevant operation data as input, a calculation of train flow path is carried out with satisfving path plan.
