| 摘 要： | 在假定部件不能"修复如新"的条件下,基于几何过程模型研究单部件系统的最优维修策略.推导出系统经长期运行在单位时间内期望效益和期望可用度的表达式,在此基础上建立可用度和费用的维修策略权衡优化模型,为部件追求不同系统目标而进行维修活动提供决策依据.在建立维修策略优化模型时,考虑了部件的检测策略和基于系统状态的预防性维修.最后给出对模型进行求解的算例.

| Abstract: | In this paper,an optimal maintenance strategy for the repairable system consisting of one component is studied assuming that the repair component after repair is not "as good as new" by using the geometric process.The expressions of the long-run average benefit per unit time and the long-run average availability per unit time are calculated.Accordingly,the optimal tradeoff model of cost and availability is presented,in order to provide reliable guidance for decision making for the maintenance of components ... |
