A performance-margin-based belief reliability model considering parameter uncertainty

Research output: Chapter in Book/Report/Conference proceedingConference contributionpeer-review

Abstract

Belief reliability is a newly developed reliability metric considering aleatory and epistemic uncertainty. Since Performance Margin (PM) is an important concept in belief reliability, there is a great need to develop PM-based belief reliability models. In this paper, we consider the parameter uncertainty of PM and propose a new belief reliability model. In this model, the performance parameter and its threshold, which determines the PM of a system, can be modeled as an uncertain variable or a random variable, and three belief reliability formulas are put forward based on different cases. To illustrate the model, a case study about belief reliability estimation of a contact recording head is performed.
