摘　　要：为研究疫情期间北京地铁“超常”条件下的“超强”运行图编制方法,根据“双超”运行图编制流程提出一种面向车厢低满载率的双层规划优化模型。上层模型基于客流的时空分布规律优化列车的开行方案;下层模型优化列车运行图中全周转运行时分,停站时分,运行时分,折返时分等要素。双层规划模型转化为线性模型并用CPLEX软件通过迭代算法求解“双超”运行图优化问题。基于亦庄线数据对优化编制方法的有效性进行验证。在车底全部投入运营的条件下,优化后早高峰上行、下行最大列车满载率分别降低了21.1%和16.6%;晚高峰上行、下行最大列车满载率分别降低了23.2%和32.3%。本文方法为疫情下城轨运输体系提供了良好地支撑。This paper presents the designing method of the special train timetable with high demands under unusual conditions like epidemics.Considering the designing process of the special train timetable,this paper proposes a bilevel programming optimization model to reduce vehicle's loading rate with high demand.The upper model optimizes the operation plan based on the distribution characteristics of passenger flow in time and space.The lower model optimizes the parameters of train timetable which include the cycle time,dwell time,running time between stations and turn-back time.The optimization problem for the special train timetable can be linearized and then solved iteratively using CPLEX solver.The effectiveness of the proposed optimization method is verified through the data of YIZHUANG line of Beijing Metro.The simulation results show that the maximum train loading rates for inbound and outbound directions are reduced by 21.1%and 16.6%respectively during the morning peak when all available trains are operated for the line.The maximum train loading rates for the inbound and outbound directions are also reduced by 23.2%and 32.3%during the evening peak.The proposed approach can be used to support the urban rail transit timetable creation during the epidemics.
