摘　　要：应用copula函数来表示由两类失效部件组成的相依串联系统和相依并联系统的可靠性,并对这两种系统的可靠性进行比较,得到了使这两种相依系统的可靠性之间的大小关系成立的一些条件.In this paper copula function is applied to detnonstrate the reliability of the system involving two dependent components with two types of failure. The reliability of the 2 - unit series system was compared with the that of the 2 - unit parallel system under many special cases and come to some results.

关 键 词：可靠性 两类失效部件 相依
