Abstract :
Uncertainty representation and management are important in prognostics and health management (PHM). This paper first introduces concept of uncertainty as well as the importance of uncertainty in PHM. And the processing of uncertainty is mainly summarized, containing the uncertainty representation, estimation and management. The main approaches for uncertainty processing, such as probability theory, fuzzy set theory, evidence theory and rough set theory are analyized systematically in detail.
