摘　　要：基于Copula函数,对部件寿命和故障后修理时间存在相依关系的单部件可修系统的可靠性进行分析,得出系统的可靠度与(0,t]时间中系统的平均故障次数都与独立情形时相同,只有系统的瞬时可用度与其Copula有关.This paper carried out an reliability analysis of one-unit repairable system in which the dependence relation exists between the unit＇s operating life and the repair time after breakdown based upon the Copula function,and eventually arrives at the conclusion of some reliability quantity indices,such as the system′s reliability and availability,the average breakdown times during the period of 0 to t,and so forth.

关 键 词：COPULA 可靠度 可用度 平均故障次数
