基于FGM函数的不同贮备部件下两部件串联系统的优劣分析

基于FGM copula函数对带有不同贮备类型的两部件串联系统的优劣进行分析。分别讨论了带1个冷贮备、带1个温贮备和带1个热贮备部件的两部件串联系统的单位成本下的可靠度。并用1个实例验证了理论分析结果的有效性,得到部件FGM相依条件下,当系统的使用寿命低于7595 h,选择对系统增加温贮备性价比更高;当对系统的使用寿命高于7595 h,选择对系统增加热贮备性价比更高。

Bayesian and Multiple Bayesian Analysis of the Reliability Performances for Series System with Cold Standby Units

By using Bayesian and multiple Bayesian method, the failure probability, reliability and mean time to failure(MTTF) of series system with cold standby units are estimated. At last, we compare the two estimators by means of Monte_Carlo simulation.
