A system model with the opportunistic maintenance is built by using the theory of renewal process and the calculation methods of system transient and steadystateavailability is also presented.
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。

In addition, we also investigate the parameters "effect on the steady-stateavailability by numerical comparison and analyze the benefit of the system."
此外，还通过数值比较考察了系统参数对系统稳态可用度的影响，并对系统进行了效益分析。

The formulas for instantaneous availability and limiting steady-stateavailability are presented for several cases which people meet often in practice.
