Generalized Inverse Rayleigh Reliability Estimation of (3+1) Cascade Model

Abstract

In this paper presents the R reliability mathematical formula of (3+1) Generalized inverse Rayleigh Cascade model . The reliability of the model is expressed by Generalized inverse Rayleigh random variables,which are stress and strength distributions. The reliability model was estimated by seven dissimilar methods ( ML , Mo , LS , WLS , Rg ,Pr and Pi ) and simulation was performed using MATLAB 2012 program to compare the results of the reliability model estimates using the MSE criterion , the results indicated that the best estimator among the six estimators was ML and Pi.
