编组站调车场线群的调整运用模型

Adjustment and Application Model of Shunting Yard Track Group in Marshalling Station

为了提高编组站调车场线路的有效利用率,借鉴到发线合理运用及调车场线路固定使用方法的有关研究成果,定义了调车场线群、线域的概念,建立了以股道占用、调车线最高集结车辆数、解体时间区间与编组时间区间冲突和总车流量为约束条件,以出发列车集结占用线路数量、调车线集结车流去向的分散度和调车线的空闲车数为目标函数的调车场线群调整运用模型,并结合编组站配流模型生成的配流方案及列车的解编顺序方案,给出了模型的解决思路。

In order to increase effective use rate of shunting yard tracks in marshalling station,by referring relative research results on reasonable use of arrival-departure track and fixed use method of shunting yard tracks,this paper defines the concepts of track group and track area in shunting yard,establishes the track group adjustment and using model of shunting yard with restriction conditions of track occupation,maximum concentrated vehicle number of shunting line,conflict between uncoupling time interval and formation time interval as well as total vehicle flow,with object functions of occupied track number of departure train concentration,decentralization of concentrated vehicle flow direction in shunting line and the idle vehicle number in shunting line.Then,the paper provides a solution idea for the model by combining the allocating scheme occurred by marshalling station allocating model with train uncoupling order scheme.
