Failure mechanism behavior and reliability of non-repairable system with functional dependence

摘要

In the case of system with function dependent behavior, the failure of one component will cause dependent components within the system to become unusable or workable, and the state of failure mechanisms of dependent components will be changed. Reliability study of functional dependence has never refer to failure mechanism level. This paper use a reliability evaluation method considering failure mechanism behavior in components with functional dependence, which includes the second type of trigger and suspension. FMT and FDEP gate are used to express the failure mechanism behavior. A case study is utilized to illustrate the failure mechanism behavior in system, a BDD model of system and some reliability curves are obtained at the end of this paper.
