In this paper, we consider Bayes estimation of reliability for a series stressstrength system with two correlative components. Let X_i be the strength of component i, i= 1, 2, Y be the stress of the system, (X_1,X_2)~BVE(), Y~E (μ), they be independent. Let = (λ_1, λ_2, λ_0)have a independent Gamma prior distribution and a noninformative prior distribution, the Bayesian estimate and the Bayesian confident interval of R () are given in this article, where R (λ) = P_r (X>1 Y, X_2>Y丨λ).
