摘要:
［目的］为改善调车作业对城市轨道交通车辆段回库列车股道运用的影响，提高城市轨道交通列车检修效率，需在考虑调车作业约束的情况下对城市轨道交通回库列车股道运用进行优化。［方法］将转场列车视为回库列车，按调车入库时间分别编入早、晚回库计划中，以最少调车次数和最小检修走行距离为目标函数，考虑调车作业约束，基于改进灰狼算法开发了一种先对单个独立回库计划（早回库、晚回库）进行规划,再对所有回库计划通盘规划的列车股道运用多目标优化模型。以天津某地铁线路车辆段的回库列车股道运用方案为算例,验证所建立优化模型的有效性和可行性。［结果及结论］通过所提模型求解得到的列车股道运用方案的走行距离比人工方案减小65.7%（其中早回库阶段减小25%，晚回库阶段减小77.7%），且列车调车次数为0。该模型能在满足城市轨道交通回库列车洗车、检修、次日发车等调车作业约束的基础上实现回库列车股道运用的最优化编排。
Abstracts:
［Objective］ To improve the impact of shunting operations on the track utilization for the depot-returning urban rail transit trains and enhance the train maintenance efficiency, it is necessary to optimize the track utilization of the depot-returning train with shunting operation constraints. ［Method］ Regarded as a depot-returning train, the transition train is incorporated into the early and late depot-returning plans respectively according to the shunting time. With the minimum number of shunting operations and the shortest running distance for maintenance as the objective function, and taking the constraints of shunting operations into account, a multi-objective optimization model for train track utilization is developed based on an improved grey wolf algorithm, featuring first for individual independent depot-returning plan (early and late depot-returning) and then for all depot-returning plans as a whole. In a case study of the track utilization plan for the depot-returning train on a metro line in Tianjin, the effectiveness and feasibility of the established optimization model are verified. ［Result & Conclusion］ The train running distance of the track utilization plan obtained from the proposed model is reduced by 65.7% compared with the manual plan (with a 25% reduction in the early depot-returning stage and a 77.7% reduction in the late depot-returning stage), and the number of train shunting operations is zero. The model can achieve the optimal arrangement of track utilization for the depot-returning train on the basis of satisfying the constraints of shunting operations such as train washing, maintenance, and departure on the next day.
