Abstract
The invention relates to a method and an apparatus for executing a grade change in a paper machine, in which method a grade change is executed by determining, in advance, target ramps for different process variables, which are ramped according to said ramps during the grade change. Data about the grade changes already executed is collected, whereafter data about successful grade changes is selected and the grade change models to be used are determined on the basis of this data, and the target ramps are determined by means of these grade change models.
