1. A method for creating a representation of a plant and incorporating it into a run time prediction system for generating predicted output values representing the operating parameters of the plant during operation thereof, comprising the steps of:

  • providing a historical database representing the operation of the plant and comprised of data associated with plant inputs and plant outputs;

    extracting data from the historical database and creating a dataset of variables corresponding to the inputs and outputs from the historical database;

    creating an off-line predictive model of the plant utilizing the created dataset to predict a plant output and defined by off-line model parameters;

    creating an on-line model for generating predicted output values in real time during the operation the a plant and defined by on-line model parameters; and

    replacing the on-line model parameters with the off-line model parameters after generation thereof.
