Bayesian reliability demonstration test in a Design for Reliability process

This paper illustrates how a Bayesian reliability demonstration test (BRDT) approach can be, and sometimes must be, integrated into a Design for Reliability (DFR) process. A simplified and effective BRDT algorithm is given, based on the prior distribution characteristics of reliability in the DFR process. The BRDT can significantly reduce sample size in reliability demonstration test, and serve as a powerful validation tool in DFR.
