基于条件失效率的串和并联系统的失效率刻画

由于条件失效率有很好的直观意义且易获得,用它们去刻画相关部件组成的串或并联的系统失效率是一条有效的新途径.但并联系统失效率的表示过于复杂.由此,新定义过程失效率向量,但仍基于条件失效率,从另一方面描述并联系统的整个失效状况,并用Basu定义二维失效率说明其应用.最后,将以上两种刻画方式统一为系统过程失效率函数.

The Depiction of Series and Parallel System Failure Rate based on Conditional Failure Rate

An effective new way is proposed to define the system failure rate of series or parallel system consisting of two dependent components.But the way of parallel system is too complicated. So, A new failure rate process vector is put forward to describe the failure process of parallel system, and applied to explain Basu′s bivariate failure rate. Finally, two ways above are unified for the system failure rate process function.
