1. A method for determining a relationship between a metal temperature of a turbine component and an operating condition of a turbine housing the component, comprising:

  • develop a thermal model of the turbine component;

    measure a plurality of turbine operating parameters for a period of time;

    reduce the number of operating parameters;

    develop an operating history by reviewing the operating parameters for the turbine;

    identify a damage mechanism to be evaluated for the turbine component based on the turbine operating history;

    develop an algorithm based on the operating parameters to approximate the component metal temperature;

    develop rule sets of algorithms; and

    use the rule sets of algorithms to determine the turbine component metal tempemture so the component metal temperature is humanly perceptible.
