Abstract
An exemplary method implemented by a computing system determines a prediction of degradation of components in a complex vehicle to enable cost effective maintenance and enhance vehicle operational availability (vehicle readiness for missions) based on currently measured performance-based parameters associated with the respective components. Residues from models of the components reflect differences between performance as determined by the models of the components and currently measured actual performance parameters. The residues are used determine a level of degradation and a rate of change of degradation for the respective components. The remaining useful life (RUL) of the respective components is the projected/predicted time of remaining acceptable performance of the respective component, and is based on the current degradation level, the rate of change of degradation, and a stored threshold level of degradation that is a maximum amount of degradation that is acceptable.
