高速综合检测列车交路计划优化方法研究OA北大核心

High speed comprehensive inspection trains are crucial for ensuring the safety and efficient operation of the high speed railway system.This paper proposed a bi-level optimization model for the routing scheme of high speed comprehensive inspection trains.The upper level is to optimize the inspection routes,while the lower level is to optimize the inspection timings of high speed comprehensive inspection trains.By introducing intermediate variables to decouple the nonlinear constraints and designing the supporting solution algorithm based on the Gurobi optimizer,the model simultaneously achieved the objectives of optimal monthly inspection routes,the most reasonable allocation of rolling stock,minimal changes to the monthly inspection scheme of high speed comprehensive inspection trains,and optimal adaptability of crew members.Besides,taking the inspection scheme in a certain month of the high speed comprehensive inspection trains as an example,the paper verified the feasibility and effectiveness of the optimization method.The results demonstrate that this method significantly improves the efficiency and task allocation balance of the high speed comprehensive inspection trains,and can provide theoretical and methodological support for optimizing the actual inspection work of high speed comprehensive inspection trains.
