Zero-failure accelerated reliability demonstration test method based on degradation model

Zhang Huirui

Strategic Study of CAE 2015, Volume 17, Issue 5,   Pages 31-37

Abstract:

Traditional life demonstration test is conducted under normal conditions and fails to use degradationtest can be terminated early when this prediction does not cost unacceptable risk.Thus it is necessary to propose a method that take advantage of both degradation data and acceleratedmodel，then the minimum sample size of different test time can be picked.The article also use optimal plan to give expected test time and give deciding rules of terminating the
