摘　　要：配流方案是阶段计划的关键内容,在作业中将任务交由可用度较高的资源执行,能够在较大程度上提高计划的兑现率.考虑编组站实体资源的空闲度与可信度,给出了资源可用度的计算方法.在此基础上,综合考虑成功配流的自编始发列车数量、车辆在站停留时间、编组站整体资源的可用度,建立了基于资源可用度的编组站配流模型,并通过分层优化方法降低求解难度.算例结果表明:考虑资源可用度的编组站配流模型,其解编系统的资源可用度增幅均在5%以上;编组系统资源可用度的改善更加明显,在时间段3~8增幅约为18.9%.The wagon-flow allocating is the key content part of the stage plan.If the operation is carried out by the resource with higher availability,the probability of completion by plan can be increased to a large extent.The idle degree and reliability of entity resources of marshalling station are analyzed,and the availability calculation method of marshalling station resources is designed.On the basis of this,the dynamic wagon-flow allocating model of marshalling stations based on resource availability is established based on the maximum resource availability of marshalling stations.An example is selected and the results show that:after the optimization of the model,the increase of resource availability of the system is more than 5%;compared with the break-up system,the availability of marshalling system is improved more obviously;the increase of resource availability of the marshalling system is about 18.9%in the interval of 3~8.
