Abstract
In a method for the production of a fibrous web, especially a paper or cardboard web, an automatic ash control system and an automatic retention control system for the reduction or suppression of an interactive build-up of the two controls are linked via a model for the dependence between the filler addition and the retention agent consumption. A computer assisted quality control system is also cited.

A method for the production of a fibrous web, comprising the steps of:
- linking an automatic ash control and an automatic retention control through a model for a dependence between a filler addition and an average retention agent consumption;
- and
- suppressing an interactive build up of said automatic ash control and said automatic retention control.
A computer assisted quality control system in a paper machine, comprising:
- an automatic ash control system;
- an automatic retention control system;
- and
- a model for a dependence between a filler addition and an average retention agent consumption, said automatic ash control system being linked to said automatic retention control system through said model to suppress an interactive build up of said automatic ash control system and said automatic retention control system.
