摘　　要：针对城市轨道交通高峰期沿线部分车站的拥挤问题,提出列车开行方案和线路客流控制协同优化策略.以乘客总延误和站内控制节点控流强度最小化为目标,综合考虑行车条件、客流动态加载过程和设备设施安全约束等条件,构建了多目标规划模型.通过引入0-1变量对非凸约束条件处理以及利用评价函数对多目标函数处理,把模型转化为等价的单目标混合整数线性规划模型,利用通用代数建模系统编程调用求解器直接求解.算例结果表明,所建模型会有效降低站台乘客集聚程度、减少乘客总延误时间,从而保证运营安全的同时提高了系统效率.In order to relieve passenger congestion at crowded stations along the rail line during peak hours,this paper proposes a new collaborative optimization strategy for both train scheduling and passenge r inflow control.Considering all factors of traffic conditions,passenger dynamic loading processes,and equipment and facilities security constraints comprehensively,a multi-objective programming model was set up with the purpose of minimizing the total delay time of stranded passengers and the inflow con trol rate.By introducing 0-1 variables to deal with non-convex constraints and using evaluation functions to cope with multi-objective functions,the model is transformed into an equivalent single objective mixed integer linear programming model,whose solution can be provided directly by a solver called GUROBI.It was verified that the proposed optimization model could prevent passenger accumulation on platforms,decrease the total passenger delay time,leading to more efficient and safer operations of the systems.
