Abstract : The failure rate lambda, of components with exponential failure times, because of the manufacturing process of the components, behaves as a random variable. Assuming lambda is Gamma distributed with shape parameter alpha and scale parameter beta, the reliability estimate of the components can be expressed as R prime (t) = 1/(1 + (beta prime)t) to the (alpha prime) power where (alpha prime) and (beta prime) are the maximum likelihood estimators of alpha and beta respectively. The accuracy of this estimate is analyzed when the distribution of lambda is discretely distributed rather than gamma distributed. (Author)
