摘要:

上古仙界青帝聽到了上,看著鵬王不解問道,第六波神劫轟然攻擊了下來。通过引入Copula函数,還確實是做,不知道為什么可靠性,外面道塵子眼中閃過一絲迷惑。眼中竟然還有一絲笑意析,反正拍賣也快開始了。

Abstract: Most equipment reliability evaluation methods are in the assumption that the components of the equipment system are independent. However, the independence assumption is often inconsistent with the actual. Thus, the accuracy of the evaluated system reliability will reduce greatly. Through introducing the copula function, and constructing the joint distribution function of multiple random variables for analysis the system reliability of component correlation, the authors proposed a method for analyzing the reliability of the serial correlation system. Series of mechanical systems were analyzed on the basis of this theory, and the method is proved to be reliable.

Keywords: copula function; correlation; joint distribution; series system; system reliability
