    摘要: A mathematical model for a metallurgical engineering system and a method for optimizing the operation of a metallurgical engineering system by means of said model. A plurality of units (7-12) of a metallurgical engineering system (6) are modeled by means of a mathematical model. Said units are associated with supply and discharge media flows. In order to optimize operation of the system (6), structural parameters are supplied to an optimization computer (1) by a user (5). The structural parameters establish at least the number and type of units (7-12). On the basis of start parameters, which describe the initial states of the units (7-12), and an evaluation criterion (K), the optimization computer (1) determines optimized operating parameters according to an optimization algorithm (A) using said model.

    摘要: In a computer-implemented process modeling and simulating environment, an analyzer receives a process model with parameters in combination with data from previous or planned process performances. An analyzer receives a simulation target from a user, calculates evaluation results that represent the influence of the parameters in view of the simulation target, and presents the evaluation results as indicators to the user. Upon receiving modifications to the performance data, the process is simulated with modified performance data. Alternatively, the evaluation results are converted to computer instructions to automatically modify the process parameters.
