The invention relates to the technical field of traffic, and discloses a marshalling station arrival field track application optimization method and system oriented to virtual marshalling, so as to improve the throat trafficability of a marshalling station arrival field in a stage plan. The method comprises the following steps: constructing a parking lot throat area directed graph; dividing arrival field track bundles according to the directed graph; determining a virtual marshalling and the number of trains in the virtual marshalling, selecting a station track bundle with the number of stations closest to the number of the trains in each current idle station track bundle to arrange the train receiving, and directly arranging the train receiving by the screened station track bundle when the number of the trains arriving in the train virtual marshalling is smaller than or equal to the maximum number which can be accommodated by the screened station track bundle; otherwise, after each idle station track of the screened station track bundle is connected into a train according to the sequence, the virtual marshalling mode of the exceeding part of the train and the front train is removed, whether a new virtual marshalling can be formed or not is judged again, and the like, and distribution of the train receiving station tracks and the routes of all the virtual marshalling trains in the stage plan is completed.

本发明涉及交通技术领域，公开一种面向虚拟编组的编组站到达场股道运用优化方法及系统，以提升阶段计划内编组站到达场咽喉通过能力。本发明方法包括：构建车场咽喉区有向图；根据有向图划分到达场股道束；确定虚拟编组及该虚拟编组内列车数量，选择当前空闲的各股道束内股道数量与列车数量最相近的股道束安排接车，当到达列车虚拟编组内列车小于或等于所筛选股道束最大可容纳的数量时，直接以筛选的该股道束安排接车；否则，以所筛选股道束每条空闲股道按先后顺序分别接入一辆列车后，将超出部分的列车与前车解除虚拟编组模式后重新判定是否能构成新的虚拟编组，依此类推，完成阶段计划内各个虚拟编组列车的接车股道和进路的分配。
