摘要
可靠性理论绝大多数都是在系统中部件完全独立的前提下对系统进行的可靠性研究。由于实际的需要系统中部件经常会出现相依的情形。Copula函数的出现,为研究相依性提供了一种有效的方法。在一些学者应用Copula函数研究部件全相依的基础上,研究了部件部分相依情形时相关模型的可靠度、失效率等可靠性指标。
The majority reliability researches of system suppose that parts are in the condition of independence based on the reliability theories.Components of the system are often dependent because of the actual needs.The appearance of Copula function provides an effective method for the study of dependencies.The reliability,failure rate and other reliability indices of the related models are studied involving partial dependent components based on some scholars studies which deal with all dependent components.
