The past decades have witnessed an increasingly growing interest to prognostics and health management (PHM) in both academic and industrial communities, including electronics, energy industry, aeronautics and aerospace, manufacturing, nuclear plants, etc. As a key to PHM, the life prediction of deteriorating systems has been attached great importance by scholars and engineers in the related fields. In this report, we will discuss several frequently used models for life prediction, including physics-based model, experience based model, statistical model, degradation model, regression models, fusion model, etc. In addition, several new advances and future directions will be discussed as well.
