Theoretical Fundamentals of the Discrete Operational Lifetime

Abstract

The reliability of complex engineering objects is affected not only by the duration of the failure-free service (the continuous lifetime) but also the number of no-failure actuations to switch on the object into operation or switch it off (the discrete lifetime). The aim of this work is to fill this gap in part.
