摘要/Abstract

摘要： 为研究部件自身价值变化对其维修决策的影响，以动车组四级修时需更换的部件为研究对象，结合我国动车组现行的多级非完美维修方式，建立了一种考虑动态折旧成本的动车组部件两级非完美预防性维修优化模型，该模型以动车组部件的等效役龄计算其相应的折旧成本。进一步研究了部件折旧成本与故障率变化相关联的维修决策方法。研究结果表明，与不考虑部件折旧成本的维修模型相比，该模型兼顾了部件的生产运行和维修活动对维修决策的影响，能够更好地平衡预防性维修成本和故障维修成本，使模型更具维修经济性。

Abstract: Aiming at the components that needed to be replaced during the EMU maintenance(Level Ⅳ), the influences of the value change of the components on the maintenance decision were studied. Based on the current multi-level imperfect maintenance actions of EMU in China, a bi-level imperfect preventive maintenance optimization model was established considering dynamic depreciation costs. The proposed model calculated the depreciation costs of components through the equivalent service age. And the maintenance decisions were further investigated considering the relationship between depreciation costs and the failure rate. It is shown that compared with the maintenance model without considering the depreciation costs, the proposed model takes into account the influences of the production operations and maintenance activities on the maintenance decisions. It may better balance the preventive maintenance cost and failure maintenance cost，and achieve more economical.

Key words: depreciation cost, electric multiple unit(EMU) component, preventive maintenance, bi-level imperfect, maintenance decision model
