PROMIS methodology for prognostic health management

This paper describes the basic concepts of the PROMIS methodology for system´s Prognostic Health Management. The key elements of the PROMIS methodology are: (i) system health is monitored by continuously measuring so-called Condition Parameters (CPs)-representing the component´s physical condition-of critical system components, (ii) CPs are derived using model-based estimation processes so that the existing set of sensors is exploited as much as possible, and (iii) in order to compute the remaining lifetime of components, the effects on system health of system load is taken into account
