摘要
针对接触网检修计划人工编制效率低又难以实现优化的问题,将接触网检修计划编制转化为一个规划优化问题,利用整数规划方法,同时考虑接触网检修作业的连续性,将设备检修状态作为决策变量,以超周期惩罚费用与检修路径代价最小为优化目标,建立基于弹性周期区间的接触网检修计划自动编制模型,并基于多目标规划中分层序列法提出模型的启发式求解算法.通过实际算例验证证明:该方法可实现接触网检修计划的自动编制与优化,编制时间相对于人工节省99.98%,巡检路径节省33.16%,提高了接触网检修计划的编制效率和效果.
As manual compilation on the maintenance plan of catenary systems is low efficient and hard to optimize,it is converted into a plan optimization problem.An automatic compilation model of catenary maintenance plans is established on the basis of elastic period interval.It uses the integer programming method,considers the continuity of catenary maintenance operation,sets the maintenance status of equipment as the decision variable,and takes the minimal penalty cost and maintenance path cost as the optimization objective.A heuristic algorithm to solve the model is designed on the basis of the hierarchical sequence method in multi-objective planning.The case study shows that this method can realize the automatic compilation and optimization of the catenary maintenance plan,save 99.98%of compilation time and 33.16%of inspection path in comparison with manual work,and improve the compilation efficiency and performance of catenary maintenance plans.
