Abstract
Redundancy allocation to the system is one way to improve the reliability and efficiency of the system. Adding a standby component to the system is an important factor in improving system performance and usually will incur some costs to the system. In this paper, we investigate the stress-strength reliability of a k-out-of-n: G system in a Weibull-H model. Also, in order to increase the stress–strength reliability and decrease the costs simultaneously, we obtain the optimal time to activate the standby component to the working state,in some cases related to the Weibull-H model.
