Chapter 2 : Prognostics. Part : Industrial Prognostic - An Overview.
Résumé
Prognostics is nowadays recognized as a key feature in maintenance strategies as it should allow avoiding inopportune mainteance spending. Real prognostics systems are however scarce in industry. That can be explained from different aspects, on of them being the difficulty of choosing an efficient technology : many approaches to support the prognostics process exist, whose applicability is highly dependent on industrial constraints. Thus, the general purpose of the paper is to explore the way of performing failure prognostics so that manager can act consequently. Different aspects of prognostics are discussed. The prognostics process is defined and overview of prognostics metrics is given. Following that, the "prognostics approaches" are described and discussed. The whole aims at giving and overview of the prognostics area.
