两类双部件并联系统的可靠性模型分析

研究了两相关部件并联系统可靠性模型，其寿命服从二维指数分布。修理时间均服从一般分布。部件不能“修复如新”，运用几何过程和补充变量法，求解系统各状态下的可用度，并进一步导出系统的一系列可靠性指标。

Reliability analysis about a system that consists of two dependent parallel components

? This paper considers a two unit parallel system in which the lifetimes of the units are dependent and distributed by a bivariate exponential distribution. The repair time of the units is assumed to be general distribution. The either of the units can not be repaired as good as new. Under the assumptions, the authors have drawn some reliable conclusion by using geometric process and the method of supplementary variable.
