具有时间检测策略的温贮备系统可靠性

Reliability analysis on warm standby system of two different components with time test strategy

针对由两不同型部件组成的且贮备部件考虑时间检测策略的温贮备可修系统进行可靠性研究,利用马尔可夫更新过程理论,得到了系统的瞬时可用度、平均故障次数等可靠性指标的Laplace变换(或Laplace-Stieltjes变换)表达式以及系统的首次故障前平均时间,该结果对于提高温贮备可修系统的可靠性具有一定的参考价值与实际意义。

A warm standby repairable system consisting of two different components with the standby component using time test strategy is investigated in this study.By using Markov renewal process theory,the Laplace transform expressions such as instantaneous availability and mean failure times are derived and the MTTFF is obtained.The study results provide a useful reference for improving the reliability of a warm standby system.
