Method of carrying out an optimized fiber or paper manufacturing process

Claim 1

A method of carrying out a fiber or paper manufacturing process using a plurality of successive method steps in which defined process steps are carried out by means of predefinable chemical and physical sequences and optimization of product properties including mechanical, optical or other selected products properties as target variables is performed on the basis of measured values and characteristic variables formed from said measured values, if appropriate by using state models, wherein said target variables and said characteristic variables are transformed on a unitary basis in the form of price per unit quantity and/or price per defined product quality and wherein said characteristic variables of all the individual method steps which influence the target variables of the respective end product of the method are registered online and are used directly or indirectly online to control or optimize the overall process, said characteristic variables being formed both on the basis of the starting materials or raw materials and of the chemicals, auxiliaries and energy supplied in the successive method steps as well as of the materials and emissions to be disposed of.
