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.

Systems and methods for providing a dynamically synchronized instance to a network device. A repository database stores a process model instance having a layout defined by data elements. A design tool processor coupled to the repository database provides the instance to a user device and a network device. The user device modifies data elements of the instance to generate a first version instance, and the design tool processor generates a dynamically synchronized instance for storing and serving the dynamically synchronized instance to a network device.

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.
