Stress - Strength Reliability Estimation for Parallel Redundant System Based on Weibull-Ryleigh Distribution
Abstract
Estimation for reliability of a parallel redundant system with independent stress and strength Weibull-
Ryleigh probability density functions is considered. Estimation of the reliability parameters was
conducted according to three methods, namely maximum likelihood, moments and percentiles methods.
Finally, the reliability estimate was calculated and the best method for estimation for each case was given
using the mean squared error criteria. It was found that the best estimation method is the percentiles
method.
