基于共因失效的系统可靠性分析

System Reliability Analysis Based on Common Cause Failure

详细介绍了共因失效的定义和预测共因失效的β模型,说明了衡量共因失效的β因子的估算方法,阐述了共因失效对系统可靠性的影响。通过典型的案例分析表明:考虑了共因失效后,系统的安全性和可靠性会降低。最后提出了降低和减少共因失效的措施。

The definition of common prediction are introduced in detail. cause failure and β model for common cause failure The estimation calculation method for ＂β＂ factor is explained. The impact of common cause failure on reliability of system is expounded. It is concluded the system safety and reliability are reduced with consideration of common cause failure through typical case study. Countermeasures to reduce and eliminate common cause failure are put forward.
