摘要
本文给出了一种以故障次数为基础的系统预防性维修策略.对于具有Weibull故障流的系统,作者推出了若干定理及模拟Weibull过程的方法.在此基础上,给出了在新策略下系统可用度及平均费用的计算公式.最后,对一个算例给出了计算及仿真结果.
In this paper, failure times based on preventive maintenance strategy is presented. For system of weibull failure process, several useful theorems and a method for simulating weibull failure process are given. Based on them, the formula for availability and average cost under the new strategy are presented. Finally, numerical and simulation results are given for an example.
