A simple discrete reliability growth model and its application in project selection

Research output: Contribution to journalArticle


Most existing reliability growth models ignore the reliability test/improvement process, where engineers identify distinct failure modes through tests and redesign the product/system to remove these modes. In this paper, we present a discrete reliability growth model, which is similar to the Crow's projection and extended reliability growth models but without the doubtful assumptions implied by these models. We demonstrate the use of our model in the project selection of reliability improvement projects during system redesign.
