Abstract
A hierarchical uncertainty model of reliability is studied when a type of probability distributions of the component times to failure is known, but their parameters or some of parameters are defined by experts with corresponding degrees of belief. Two methods for computing the reliability measures are developed and analyzed from their practical application point of view. A procedure of updating the beliefs after observing a failure is investigated. Numerical examples illustrating the proposed model are given.
