Abstract:

One of the problems that has been of concern for a number of years is the following Suppose that there exists a series system of m exponentially lived components and it is required that the system be qualified for service by demonstrating a reliability that equals, or exceeds, a specified value 1 - alpha, with a confidence level at least 1 - gamma Here alpha and gamma are small. The paper addresses the question of how this can be demonstrated using only data on the reliability of the components, where the reliability design goals for each component must be apportioned, as well as the confidence levels at which the design goals must be met in order to satisfy the overall system reliability requirement.
