1. A method to predict equipment life comprising:
- making available a set of input parameters, wherein the making available comprises making available an operating condition, a degraded abnormal health condition, and a deterioration condition;
executing a computational model with the set of input parameters to define at least one modeled operation attribute margin;
comparing the modeled operation attribute margin defined using the set of input parameters absent the degraded abnormal health condition with a corresponding modeled operation attribute margin defined using the set of input parameters comprising the degraded abnormal health condition to develop a normalized operation attribute margin;
defining a health index based upon the normalized operation attribute margin;
defining a model of a health of the equipment as a function of the set of input parameters;
receiving from the model of the health of the equipment at least one signal representative of a respective one of an actual sensor output relating to an actual operation attribute margin of the equipment;
predicting a remaining useful equipment life based upon a sequence of outputs of the model of the health of the equipment; and
generating a signal corresponding to the remaining useful equipment life.

Abstract
A method to predict equipment life is disclosed. The method includes making available a set of input parameters, and defining a model of a health of the equipment as a function of the set of input parameters. The method continues with receiving at least one signal representative of a respective one of an actual sensor output relating to an actual operation attribute margin of the equipment, predicting a remaining useful equipment life based upon a sequence of outputs of the model of the health of the equipment, and generating a signal corresponding to the remaining useful equipment life.
