摘　　要：客货混运新模式为我国高速铁路运营管理带来了新的机遇和挑战.鉴于此,以最小化列车停站时间、货物滞留数量和运营成本为目标,以列车到发时刻、动车组编组和货物配装计划为决策变量,为客货混运下高铁运行图与货物配装方案协同优化问题构建一类整数线性规划模型.为验证模型的有效性,以京沪高速铁路为背景进行数值实验,并调用CPLEX软件求解.结果表明:在尽可能减小对客运服务影响的前提下,所提出方法能够通过灵活决策列车时刻表及增加列车编组,提高列车运力;与采用固定列车时刻表的货物配装优化方案相比,协同优化方法能够在小幅增加列车停靠时间的情况下大幅提升货物运输量,可为相关运营部门制定客货混运计划提供一定的理论支撑.The novel mixed passengers and freights transportation mode has brought both opportunities and challenges to the operation and management of high-speed railway in China.This paper proposes an integer linear programming model for the collaborative optimization problem of train schedules and freight allocation on a shared freight and passenger high-speed railway system to minimize the train dwell time,the number of detained freight,and operating costs,where the arrival and departure times of trains,the formation of trains,and the freight allocation are the decision variables.Then,extensive numerical experiments based on the operational data of the Beijing-Shanghai high-speed railway line are conducted to verify the effectiveness of the model,and the CPLEX optimization solver is used to solve the problem.The results show that the proposed method can improve the train capacity by flexibly deciding the train schedule and increasing the train composition while minimizing the impact on the quality of passenger service.Compared to the optimization method with fixed train timetables,the integrated optimization method can significantly improve the freight transportation capacity while only a slight increase in stopping time,providing theoretical support for the relevant operational departments to make mixed transportation plans.
