Stability Analysis of a Repairable System with Warning Device and Repairman Vacation

Abstract EN

This paper considers a simple repairable system with a warning device and a repairman who can have delayed-multiple vacations.

By Markov renewal process theory and the probability analysis method, the system is first transformed into a group of integrodifferential equations.

Then, the existence and uniqueness as well as regularity of the system dynamic solution are discussed with the functional analysis method.

Further, the asymptotic stability, especially the exponential stability of the system dynamic solution, is studied by using the strongly continuous semigroup theory or C0 semigroup theory.

The reliability indices and some applications (such as the comparisons of indices and profit of systems with and without warning device), as well as numerical examples, are presented at the end of the paper.
