Abstract

The Bayesian method is widely used for reliability analysis based on small samples. In general, the Bayesian method is assessed assuming a certain kind of prior information. However, the prior information of a new product is uncertain. In this paper, we present an Objective Bayesian method for reliability assessment of products, which performance degradation process is modeled by Wiener process. We utilize the Jeffreys prior and Reference prior of Objective Bayesian to establish a model of non-information prior distribution and estimate the parameters by the Bayesian theorem. The updated parameters are then used to evaluate reliability and residual life. A case study on bulkhead sealing device with reliability degradation testing is used to demonstrate the accuracy and effectiveness of proposed method.
