研究高原地区双线客货共线铁路列车运行图与天窗一体化编制问题对保障行车安全,提升列车运行效率具有重要意义.以旅客列车总运行时间最小为目标函数,考虑了线路区间内动车组列车和货物列车不交会、天窗开设时段设定在白天等约束条件,构建了双线客货共线铁路列车运行图与天窗一体化编制的混合整数规划模型,采用商业求解器GUROBI求解模型,并设计算例进行验证.结果表明,构建的模型能够实现高原地区双线客货共线铁路列车运行图与天窗的一体化编制,并且能满足每个区间内开设4小时的综合维修天窗,保证了每日维修作业的需要.
Research on the Setting of Comprehensive Maintenance Windows for Passenger and Freight Co-line Railways in Plateau Areas
Studying the integrated preparation of double-track passenger and freight line railway train schedules with the setting of maintenance windows in plateau regions is of significant importance to ensuring operational safety and enhancing train operation efficiency.Minimizing the total travel time of passenger trains is set as the objective function,considering constraints such as non-encounter of EMU(Electric Multiple Unit)trains and freight trains within line sections,and setting maintenance windows during daytime.A mixed integer programming model for the integrated compilation of double-track railway passenger and freight line train schedules with maintenance windows is constructed and solved using the commercial solver GUROBI.Validation was conducted through designed examples.The results show that the constructed model can achieve the integration of passenger and freight line train schedules with maintenance windows in plateau regions and can meet the requirement of opening 4-hour comprehensive maintenance windows in each section,ensuring the needs of daily maintenance operations.
