Concept of certainty in residual life of a system

Abstract

Uncertainty in residual life of a system us an important characteristic of a fault tolerant system. Certainty can be viewed as a dual of uncertainty. In this paper, we introduce a residual certainty measure. We show that the residual certainty measure characterizes the exponential distribution and distribution function.Uncertainty in residual life of a system us an important characteristic of a fault tolerant system.
