摘　　要：针对接触网检修计划人工编制存在效率低、错误多等问题,从状态检修角度出发,利用威布尔分布描述接触网设备可靠度的时变特性,引入役龄回退因子考虑检修作业对接触网可靠度的影响,建立了基于时变可靠度区间的接触网检修计划编制模型,以接触网运行可靠度最大与检修作业路径成本最低为优化目标,利用启发式求解算法对优化模型进行求解。实际算例表明,该方法能实现接触网检修计划的自动编制,可避免接触网设备的过修与欠修。With regard to the low efficiency and lots of errors for manual preparation of OCS maintenance plan,starting from the state maintenance,Weibull distribution is used to describe time-varying characteristics of OCS equipment reliability,the service life regression factor is introduced to consider the influence of maintenance operation on OCS reliability,and a preparation model is established for preparation of OCS maintenance plan based on the time-varying reliability interval,with the maximum operation reliability and lowest cost of maintenance path of OCS as the optimization objectives,and heuristic algorithm is used to calculate the optimization model.The actual calculation examples show that this method is able to realize the automatic preparation of OCS maintenance plan and prevent the over-maintenance and under-maintenance of OCS.
