考虑柔性服务时限的地铁列车运行计划与货物装载优化
Optimisation of metro train operation planning and cargo loading considering flexible service time limit
摘要
Abstract
The utilization of surplus capacity of urban rail transit during off-peak hours for cargo transport is crucial for alleviating urban road congestion,minimizing carbon emissions,and enhancing the efficiency of metro operations.A linear integer optimization model is developed with the objective of minimizing passenger train car allocation costs,dedicated freight train operation costs,and cargo delivery delay penalties.The model jointly optimizes car allocation,train formation schemes,train operation schedules,and freight assignment plans.In order to validate the effectiveness of the model,an empirical study is carried out on Nanchang Metro Line 2,and the model is solved with the help of the optimized commercial solver CPLEX.The results of the example show that increasing penalties for delayed delivery can effectively reduce the average cargo delay time;deploying additional special freight trains can compensate for insufficient transport capacity,compared with the fixed grouping of special freight trains for freight transport,the flexible grouping mode can meet the transport demands of all cargo groups with only a 26 min increase in the total delay,while reducing the total operating costs by 998 yuan.This method adapts better to variations in freight demand,enables the timely transport of large volumes of time-sensitive goods,and reduces wasted train capacity.It provides theoretical support for further improving the operational efficiency of urban metro lines.关键词
