1. A method for managing an industrial process wherein a processor transforms an energy related test signal into an energy prognosis, the method comprising:

  • receiving automatically with the processor the energy related test signal comprising effective power test data indicative of electrical energy consumed by an energy consuming machine;

    partitioning automatically with the processor the energy related test signal into an energy related test sub-signal;

    applying automatically with the processor mathematical functions to the energy related test sub-signal to extract a feature set of data from the energy related test sub-signal;

    transforming automatically with the processor the feature set of data with a transformation matrix into a reduced test feature set;

    inputting automatically with the processor the reduced test feature set into a performance assessment algorithm, wherein the performance assessment algorithm is based at least in part upon a reduced training feature set derived from data indicative of electrical energy consumed during healthy operation; and

    generating automatically with the processor the energy prognosis, wherein the energy prognosis is based at least in part upon a power-based performance index calculated by the performance assessment algorithm.
