Hilaire Perera says
Prognostic Health Management (PHM) is a methodology that permits the assessment of the reliability of a system under its actual application conditions, and exercises necessary management actions.
Prognostics utilizes in-situ monitoring and analysis to assess system degradation, and determine the Remaining Useful Life (RUL) of an asset. The RUL of an asset is defined as the length of time from the present time to the end of useful life. The need for RUL estimation is obvious because it relates to a frequently asked question in industry, which is how long a monitored asset can survive based on the available information. Based on the RUL estimation, appropriate actions can be planned. Especially for critical equipment, such as aircraft engines, or inertial navigation platforms used in aerospace and weapon systems, determining if and when to take equipment out of service is important from both a cost-effective point of view and a safety point of view.
It is critically important to assess the RUL of an asset while it is in use, as this information impacts the planning of maintenance activities, the supply chain, replenishment of the inventory system, operational performance, and profitability of the owner of an asset
