摘要
机会维修是针对多部件系统提出的一类新的维修策略,主要解决部件间存在经济相关性的问题.利用更新过程理论建立了机会维修策略下的系统模型,并给出了系统瞬态和稳态可用度的求解方法.通过分析比较可知,利用更新过程稳态下的某些特性,可以不必求解更新方程而比较简便地求解系统稳态可用度.
The opportunistic maintenance is a kind of new policy for the multi-units system considering economical dependence. A system model with the opportunistic maintenance is built by using the theory of renewal process and the calculation methods of system transient and steady state availability is also presented. Then the fact is found that the acquirement of steady state availability becomes easier by use of some steady-state characteristics of renewal process.
