A Decision Making Model and its Application for Energy Conservation in Process Systems

Decision Making Models are developed for energy conservation in metallurgicalprocess system,based upon the optimization theory for large systems.These modelsconsist of the multistage Input-Output Model and Decomposition-Coordination Model.Their formulation,algorithm and microcomputer software are explained in considera-ble detail.The models of saving energy in ironmaking process system are describedand discussed as a specific application of process modeling methodology.A reason-able scheme to minimize costs and energy is worked out in ironmaking processsystem.This scheme has yielded good results in saving energy.
