THE JOINT PREDICTIVE-POSTERIOR METHOD IN THE BAYESIAN ANALYSIS OF STRESS-STRENGTH RELIABILITY

摘要

The joint predictive-posterior approach to the study of the reliability of an engineering system, under a stress-strength model, is presented in this article. This new combined approach is original, is supported by charts and graphs and can be quite useful since it allows the realistic forecasting of system reliability, with known credibility levels, ahead of real experimentation and testing results. In this article, it is concretely illustrated by several engineering applications related to a highway bridge study and a quality control problem.
