A two dissimilar unit multi-component system with correlated failures and repairs

Abstract

This paper investigates a two non-identical unit cold standby system model. Each unit is composed of n independent components arranged in a series configuration. A single repairman is available to repair a failed unit. The priority in operation is being given to the first unit, while in repair the priority is given to the second unit. The failure and repair times of the ith and jth component for the first and second unit, respectively, are jointly distributed as bivariate exponentials (B.V.E.) with different parameters. Using a regenerative point technique, various reliability characteristics have been analysed.
