Purpose The purpose of this paper is to consider the estimation of multicomponent stress-strength reliability. The system is regarded as alive only if at least s out of k ( s k ) strengths exceed the stress. The reliability of such a system is obtained when strength, stress variates are from...

In the literature of reliability engineering, reliability of the weighted k-out-of-n system can be calculated using component reliability based on the structure function. The calculation usually assumes that the true component reliability is completely known. However, this is not the case in...

This paper outlines the benefits of undergrounding power lines. We present research that reveals the reliability and operation and maintenance (O&M) impacts of electric underground lines relative to overhead lines. This research uses a comprehensive dataset from 163 US electric utilities....
