| 摘要: |
| 本文研究了一类修旧非新的两参数预防维修策略.在预防维修依赖于基准可靠度R的条件下,利用系统的相关可靠性指标建立了平均费用关于R和N(预防维修次数上限)的函数关系.进一步找到了该函数的最小值点,即得到了最优策略(R,N)*.同时通过实例说明了本文的维修策略优于文献[8]. |

| Abstract: |
| In this paper,a bivariate preventive repair policy is studied,which assumes that preventive repair does not return the system to a "good as new" condition,with the critical reliability R and number of preventive repairs N.Our aim is to determine an optimal mixed policy (R,N)* such that the long-run average cost per unit time is minimized.Finally,an appropriate numerical example is given,which shows that our new policy possesses better performance than the policy given in [8]. |
