Abstract:     A method and system for performing model-based multi-objective asset optimization and decision-making is provided. The method includes building at least two predictive models for an asset. The building includes categorizing operational historical data via at least one of: controllable variables, uncontrollable variables, output objectives, and constraints. The building also includes selecting at least two output objectives or constraints, and identifying at least one controllable or uncontrollable variable suitable for achieving the at least two output objectives or constraints. The method also includes validating each predictive model and performing multi-objective optimization using the predictive models. The multi-objective optimization includes specifying search constraints and applying a multi-objective optimization algorithm. The method further includes generating a Pareto Frontier, and selecting a Pareto optimal input-output vector.

    1. A computerized method for performing multi-objective asset optimization and decision-making using predictive modeling, comprising:

building, via a process manager application executing on a processor, at least two predictive models for an asset, the asset comprising a physical machine that is communicatively coupled to the processor, the building comprising:

categorizing operational historical data of the asset that is retrieved from a storage device, the operation historical data categorized by at least one of:

controllable variables;

uncontrollable variables;

output objectives; and

constraints;

selecting at least two output objectives or constraints; and

identifying at least one controllable or uncontrollable variable suitable for achieving the at least two output objectives or constraints;

inputting, via the process manager application, the at least one controllable or uncontrollable variable to each of the at least two predictive models;

validating, via the process manager application, each predictive model;

if results of the validating indicate a confidence level above a specified threshold, applying, via the process manager application, a live data stream of inputs from the asset to the predictive models;

if results of the validating indicate a confidence level at or below a specified threshold, selecting, via the process manager application, at least one alternative controllable or uncontrollable variable for input to the predictive models;

performing, via the process manager application, multi-objective optimization using the predictive models, comprising:

specifying search constraints, comprising:

upper and lower bounds for each input variable; and

tolerance levels representing a range of values for achieving optimal output objectives, and constraints;

applying a multi-objective optimization algorithm; and

generating a Pareto Frontier, the Pareto Frontier including optimal input-output vectors;

using results of the multi-objective optimization, selecting, via the process manager application, from the Pareto Frontier, a Pareto optimal input-output vector for deployment to the asset, the selected Pareto optimal input-output vector specifying an optimal operational state for the asset; and

re-configuring the asset, via the process manager application, using the Pareto optimal input-output vector to realize the optimal operational state.
