摘要

An iterative method for controlling and optimizing a production process of at least one of a material and a product formed out of the compound material. Thereby a production control unit is provided and three different parameter groups, namely indicating parameters, nominal parameters and correcting parameters are defined, wherein the indicating and nominal parameters may be selected out of a group comprising process parameters, material recipe parameters and product property parameters. The correcting parameters may be selected out of the group comprising process parameters and recipe parameters. As reference values, nominal parameters are provided to the production control unit. During a first production cycle at least one indicating parameter is measured and the measured values are provided to the unit. If the values deviate to much from the nominal parameters, the unit afterwards sets at least one correcting parameter on basis of the indicating parameter and on basis of the nominal parameter, thereby concerning any interaction between different parameters due to changes of any parameter.
