【Abstract】 In this paper we consider mainly minimum variance unbiased estimation of reliable probability in two multicomponent strength-stress models of Exponent-Normal and Extreme-value-Normal.In nine cases that some distributive parameter of normal, Extreme-value and Exponent etc are unknown these expressions of minimum variance unbiased estima tion of reliable probability are obtained.更多还原
