摘　　要：开行大小交路列车是应对城市轨道交通线路客流不均衡问题的有效方式,针对大小交路列车运行组织方案优化问题,提出以车辆运力与客流间的供需关系为约束,以综合减少乘客总候车时间以及地铁车辆总运营里程为目标,建立非线性混合整数规划模型,通过决策小交路折返站的位置、小交路区段的平均车头时距、大小交路列车开行比例以及大小交路列车编组数,实现乘客方和地铁运营方的综合效益最优,并讨论列车运行组织方案中不同运行参数对双方的影响,为大小交路列车运行组织方案的设计和优化调整提供参考。In urban rail transit,full-length and short-turn operation modes is an effective way to tackle the problem of unbalanced passenger flow.This paper proposes an optimization method for generating the organization scheme of these two operation modes.A nonlinear mixed-integer programming model is set up,which takes the supply and demand relationship between carrying capacity and passenger flow as constraint.By determining the turn-back stations and the average headway for short-turn section,as well as the proportion and the number of carriages for full-length&short-turn trains,the total waiting time for passengers and total operating mileage for trains are minimized in a comprehensive way.Additionally,the influence of different operating parameters in the train organization scheme is discussed,which provides a reference for design and optimization for the full-length and short-turn organization scheme.
