摘要
针对列车开行方案与列车时刻表协同优化问题进行研究,基于协同优化的基本概念和协调信息,分析了优化模型的目标函数与约束条件。协同考虑列车停站方案与列车时刻表两个问题,通过约束列车在中间站的停站时间将列车停站方案与列车时刻表联系起来,根据已知的列车运行图信息来优化列车停站方案,以列车在中间站的停站时间最小为优化目标,构建了混合整数规划模型,并设计一个小型算例,用GAMS软件求解,验证模型的可行性。
This paper studies the collaborative optimization of the train operation scheme and the train schedule.Based on the basic concepts of collaborative optimization and the coordination information,it analyzes the objective function and constraints of the optimization model.Considering both the train stop plan and the train schedule in a coordinated way and by constraining the stop time of the train at intermediate stations,it connects the train stop plan with the train schedule,and proceeds to optimize the train stop plan based on the known train operation chart.Next,taking the minimum stop time of the train at intermediate stations as the objective,it builds a mixed integer programming model,and designs a small numerical example which is then solved using the GAMS software,with results verifying the feasibility of the model.
