Availability Analysis of a Repairable k-out-of-n:GSystem with a History-Dependent Critical State

For a repairable k-out-of-n:G system with a history-dependent critical state, this paper derives the availability, the mean up time and the mean down time in one renewal cycle when the system goes into the steady state. A comparison between this system and a repairable k-out-of-n:G system without a history-dependent critical state is conducted as well.
