3个不同部件串-并联系统修复的可靠性

应用随机过程的理论 ,针对不能“修复如新”这一条件 ,给出了 3个不相同部件串 -并联系统的可靠性模型。其中有两部件寿命和修理时间服从指数分布 ,且能“修复如新” ,另一个部件修理时间的分布函数不是指数函数 ,不能“修复如新” ,系统只有一个修理工的三部件串 -并联系统的可靠性模型。通过对模型的分析 ,利用几何过程和补充变量法及其Laplace变换得出模型的可靠度、可用度等一系列可靠性指标

Reliability of a system-repairing with tree series-parallel connected units

Using random process theory, we analsys the reliability of a system with tree series parallel connected components. It is concluded that one unit of the repaired system can't be as good as new, the others units can be as good as new. We also obtain a series of useful results as reliability and availability about the system.
