Component importance in a random environment

Abstract

In a number of situations an engineering system can be set in a semi-martingale representation. Filtering this representation through the family of sub [sigma]-algebras generated by the multivariate point process of system components, we consider the innovation gain corresponding to the dynamics of component i. We define the reliability importance of component i to system reliability as the negative expected value of its innovation gain.
