Main Article Content

Nada Sabah Karam, Ahmed Mezher Marir


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.
