Abstract
In order to improve reliability, two redundant systems are considered. The system has two dissimilar components working in parallel. The failure time of the components are assumed to be exponentially distributed with different parameters. Failure of one component puts the work pressure on the second component, causing its changed (increased) failure rates. There are two repair facilities to repair the components. The repair time distribution of each server is exponential. We obtain the expressions for reliability, the mean time to system failure (MTSF) and steady state availability for both the systems.
