摘要
为优化多编组站铁路枢纽车流组织,均衡各调车系统解编能力的利用,首先,考虑枢纽内各场站改编作业能力和瓶颈区间线路通行能力限制,将列流、车流组织成本和调车系统能力利用率均衡偏差最小作为优化目标,构建带编组站分工的列流、车流组织优化模型。其次,根据场站接发列车能力生成初始方案,依据瓶颈区间线路通行-场站解集编能力调整检验;在此基础上,设计双层整数编码对匹配方案进行表述,给出匹配方案五步更新过程,并利用此过程完成匹配方案的群体迭代寻优。最后,设计实验场景,利用所提出的方法进行求解,并同不考虑编组站分工的列流、车流组织方案进行比对分析。结果显示,考虑编组站作业分工的列流、车流组织方案成本降低了9.5%,调车系统解编能力利用率均衡偏差降低了16.6%。
This study attempts to optimize the wagon flow organization of railway terminal with multiple marshalling stations and balance the disintegration and marshalling ability of each shunting yard.Firstly,we propose a mathematical programming model,it considers some constraints indicating the train formation capacity of marshalling station,the number of wagons transshipping in bottleneck railways,and the objective function of which is minimizing the total cost of wagon flow moving,accumulation,reorganization and deviation between actual capacity utilization and expected capacity utilization of shunting yard.Secondly,the initial matching scheme between train,marshalling station,and shunting yard is given by the train receiving and departure capacity of marshalling station.And the matching scheme is updated by the capacity of wagons transship in bottleneck railways,wagons accumulation,train makeup,and train breakup.After that,the matching scheme is expressed by double integer coding.And then the five phase updating approachis used to find the optimal matching scheme.Finally,the experimental scenarios are set up,and the train and wagon flow allocation scheme considering marshalling station work division is obtained by the proposed approach.The results show that the cost of train and wagon flow allocation scheme considering marshalling station work division reduces by 9.5%,and the deviation of the capacity utilization ratio of the shunting yard reduces by 16.6%.
