Bayes Plan of Reliability Qualification Testing for Weibull Aerospace Equipment

The Bayes plan of reliability qualification testing (RQT) for Weibull aero-space equipment is aiming to determine the qualification testing plan of equipment in the Weibull distribution. By prespecifying the shape parameter, the exponential distribution is a special case of the Weibull distribution. To handle these particularities, the RQT plan for aerospace equipment is determined by referring to the method under exponential. Under the prior in-formation of reliability index from similar equipment, the Bayes method and maximum risk criterion is adopted. It is well established the RQT plan of equipments with no failure and small simple size. Different methods to determine the hyperparameters are proposed and their application field also is studied. An illustration is provided by a case study on an aerospace equipment. It makes the proposed method especially suitable for Weibull aerospace with high reliability.
