摘　　要：城市轨道交通系统可以有效改善日益拥堵的城市交通,近年来我国城市轨道交通不断借鉴国外的先进经验,大胆创新,发展迅速,一些城市的轨道交通网络初具规模。编制列车车底运用计划是城市轨道交通运输组织的主要工作之一,车底运用计划的好坏影响着运输服务质量和运营成本的高低。因此,本文结合多车场、多车底编组的实际情况,考虑车场能力、线路能力等约束,基于多商品网络流问题建立多线路条件下城市轨道交通车底运用优化模型,并运用CPLEX进行求解。最后,通过案例分析来验证所建立模型的可行性。The urban rail transit system can effectively improve the increasingly congested urban traffic.In recent years,China's urban rail transit has been constantly learning from the advanced experience of foreign countries,making bold innovations and developing rapidly.The rail transit network of some cities has begun to take shape.The preparation of train bottom utilization plan is one of the main tasks of urban rail transit transportation organization.The quality of train bottom utilization plan affects the quality of transportation service and the level of operation cost.Therefore,this paper combines the actual situation of multi depot and multi car bottom marshalling,considers the constraints such as parking lot capacity and line capacity,and establishes the optimization model of urban rail transit vehicle bottom utilization under multi line conditions based on multi commodity flow problem,and uses CPLEX to solve it.Finally,the feasibility of the model is verified through case analysis.
