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 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.
