Abstract
AbstractThe reliability and safety operation of an industrial system at a low cost are the main objectives of industrial companies in order to stay competitive in a constantly growing market. This interest is fed by the fact that unexpected shutdowns can often lead to physical hazards as well as economic consequences in key sectors. Hence, fault prediction in the context of the Prognostics and Health Management (PHM) concept emerges as an important focus of the industry. Thus, this paper aims to detail the prognosis aspect and describe how it complements the different maintenance strategies. It also presents the expected benefits of the prognostic methods implementation in order to serve the PHM. More specifically, this paper provides a state of the art of existing prognostic methods used in the PHM strategy. This paper shows the diversity of possible prognostic approaches and the choice of one among them that will define a framework for industrials.KeywordsPrognosis and fault predictionPrognostics and health management (PHM)Maintenance strategies
