ABSTRACT:
The invention relates to a method for controlling an industrial process for manufacturing or processing a product, in particular for controlling the cooling line of a hot-rolling mill, said cooling line being simulated by a physical model. To optimize the cooling process, a correction factor is determined in a simple manner, whereby the product data records are saved with the correction factors that have been determined previously. For a new strip to be cooled, the saved product data records are compared with the product data of the new strip and similar data records are extracted. A new correction factor is then determined, e.g. by means of linear regression, from the correction factors of the similar product data records.
