产品生命周期维修费用估算方法研究

Research on Evaluating Product Maintenance Cost on Life-cycle

基于拆卸逻辑网络模型DLN ,提出了以更换为主要维修方式的单目标维修费用的估算方法和多目标维修费用的计算方法 .在推算产品生命周期维修费用的过程中 ,给出了零部件寿命混合排序法 ,在此基础上计算维修费用以确定维修级别和维修组合 。

Based on the model of product disassembly-logical-net(DLN), the methods for evaluating single-goal maintaining costs and multiple goal maintaining costs are presented. And the provided renewal is a chief way of maintenance. On calculating product maintenance costs on life-cycle, a method called conditional arrangement in part′s lifetime is created and applied to choosing maintaining level and maintaining combination in order to acquire product′s maintenance route on the life-cycle.
