Bayes estimation of residual life by fusing multisource information

Qian ZHAO, Xiang JIA, Zhi-jun CHENG, Bo GUO

Frontiers of Engineering Management 2018, Volume 5, Issue 4,   Pages 524-532 doi: 10.15302/J-FEM-2018034

Abstract:

Residual life estimation is essential for reliability engineering.Traditional methods may experience difficulties in estimating the residual life of products with highreliability, long life, and small sample.In this study, a Bayes model is proposed to estimate the residual life of products by fusing expert knowledgelife estimation that uses non-informative prior.
