Cost-Benefit Analysis of a Standby Retrial System with an Unreliable Server and Switching Failure

In many industries and plants, a stable power supply system with acceptable cost/benefit is essential. This paper investigates the cost-effectiveness of an unreliable retrial that includes standby generators experiences switchover failures generators. Four different configurations are included, each configuration various numbers primary Upon arrival, failed generator repaired immediately if server available; otherwise, will enter into orbit. The subject to breakdown even when idle. explicit expressions mean time-to-failure steady-state availability for derived compared. We also compare ratio among four configurations. developed results can provide managers decision reference cost reduction.
