摘　　要：城市轨道交通断面客流具有时间和空间上的波动性,应根据断面客流差异采取大小交路的运营模式。以乘客等待时间、车辆走行公里和列车运行时间最小化为目标,在列车编组可变前提下构建多目标优化模型,优化大小交路开行方案,以线性加权法将多目标优化模型转化为单目标优化模型,并以受控随机搜索算法求解。通过实例验证了模型的有效性,结果说明开行大小交路是断面客流不均衡条件下城市轨道交通运输组织的有效模式,采用大交路大编组、小交路小编组的模式能有效平衡乘客等待时间与城市轨道交通运营企业效益。The fluctuation of passenger flows at different time and locations has prompted operators to take an approach that mixes part routes and full ones. This paper, with the goal of minimizing passengers＇ waiting time, train travel time and distance, explores a multi-objective optimization by improving routing plans. The authors also use the weighted linear combination to translate the multi-objective model into a single objective which could be solved by the controlled random search algorithm（CRS）. The finding, verified by a case study, indicates the routing plans are effective in managing urban rail transport when passenger flows are unpredictable. The proposal, that highlights assembling more train cars for major routings and less for the rest, is expected to better balance the waiting time and the revenue of urban transport operators.
