Prognostics and Health Management (PHM) is a key enabler of and serves as a key component of the "Plus" portion of Condition Based Maintenance Plus (CBM+) by providing the ability to predict future health status of a system or component, as well as providing the ability to anticipate faults, problems, potential failures, and required maintenance actions.
Enhanced Diagnostics is the process of determining the state of a component to perform its function(s), high degree of fault detection & fault isolation capability with very low false alarm rate.
Prognostics is the actual material condition assessment which includes predicting & determining the useful life & performance life remaining of components by modeling fault progression.
Health Management is the capability to make intelligent, informed, appropriate decisions about maintenance & logistics actions based on diagnostics/prognostics information, available resources & operational demand.
