铁路编组站车流配流问题研究

Research on the Train Flow Distribution of Railway Marshalling Yard

在论述铁路编组站车流作业过程的基础上,确定配流的基本思路和约束条件,以及配流的原则,将车辆在编组站总停留时间最少定为配流问题的基本目标,提出配流的具体方法,采取从始发列车约束条件反推计算解体列车解体顺序,求得车流接续时间最短的最优解。并以重庆西站为例,将配流运算系统在office Excel2003的环境下投入应用。

On the basis of discussing the train flow operation process in railway marshalling yard, the basic thoughts and restriction conditions of flow distribution as well as the distdbution principles are confirmed, and the minimum total detention time of train in marshalling yard is regarded as the basic target of distribution problem. The paper puts forward the concrete method of flow distribution, and expounds that using the restriction conditions of departure train to calculate the train decentralization sequence, then seek the optimized solution of minimum train flow connecting time. With the example of Chongqing west station, the flow distribution algorithm system is put into operation under the program of Office Excel 2003.
