Abstract

A method for optimizing the operation of a metallurgical plant using a model by modeling supply and discharge media streams, predetermining structure parameters which define the media streams, linking the media streams to one another, predetermining starting parameters which describe initial states, predetermining input operating parameters, determining and outputting output operating parameters, and determining and outputting end parameters, which describe end states of the units, by the model, predetermining the structure parameters to an optimization computer by a user and transmitting the parameters from the optimization computer to a model, and determining optimized operating parameters by the optimization computer on the basis of the starting parameters and an assessment criterion in accordance with an optimization algorithm using the model, wherein the assessment criterion is predetermined to the optimization computer by the user.
