摘要
为提升多编组站铁路枢纽车流运转效率,首先,在分析枢纽内不同类型车流作业过程的基础上,以枢纽内列车进出站走行、车流改编、列车集结和转场扰动惩罚费用最小化为目标,构建数学模型;其次,根据接入枢纽铁路方向和场站接发列车能力,生成列车-编组站-调车系统初始匹配方案,进而利用转场-解集编能力对匹配方案进行调整与检验;再次,给出列车-编组站-调车系统匹配方案的双层编码方案,并利用嵌入替换-扰动-交叉操作的异步循环更新过程,完成匹配方案的群体寻优;最后,设计仿真试验对所提模型与算法进行测试.结果表明:所提方法能够完成对多编组站的合理分工,5组试验测试分别在369、422、516、641、763 s的计算时间内得到列车-编组站-调车系统匹配方案,在优化分工后的车流组织方案中,转场货车占到解车流比例均能稳定在20%,从而达到减少转场货车数、降低车流组织成本的目的.
To improve the operation efficiency of wagon flow at railroad terminals with multiple marshaling stations,firstly based on the analysis of different types of wagon flow operations at the terminal,the mathematical model is constructed with the goal of minimizing the total costs of wagons entering and leaving a station,wagon flow reorganization,wagon assembly and transship.Secondly,according to the railroad direction and the capacity of receiving and dispatching trains at the station,an initial matching scheme of the train−marshaling station−shunting system is designed,and then the matching scheme is adjusted and tested by using the transship and disaggregation capacity.Thirdly,a double-layer coding scheme for the matching scheme of the train−marshalling station−shunting system is provided,and the group optimization of the matching scheme is completed with the asynchronous iteration updating process of the embedded replacement–disturbance–crossing operation.Finally,a simulation experiment is conducted to test the proposed model and algorithm.The experimental results show that the proposed method can complete the reasonable division of assignments for multiple marshalling stations.Five groups of test tests can obtain the matching scheme of train−marshalling station−shunting system in the calculation time of 369,422,516,641 and 763 s,respectively.In the optimized division of assignments,the proportion of wagon transship in arrival wagons flow can be stabilized at 20%,so as to reduce the number of wagon transships and reduce the cost of traffic flow organization.
