FIELD: fabrics, paper.
SUBSTANCE: invention is related to pulp and paper industry. Waste paper recycling into finished paper mass is carried out in several stages of process. For extent of whiteness specified value is set for finished mass, besides extent of whiteness is measured between stages of process. Efficiency of process stage is identified with account of occurring expenses relative to increase of whiteness extent, and in system of process control dynamic tuning of separate process stages is performed with account of overall efficiency, in particular efficiency of overall expenses of process. Parametres of quality, such as extent of whiteness, are actually registered and assessed. Quality development and costs modeling is carried out in separate stages of process, and also dynamic continuous adjustment of data in separate stages of process.
EFFECT: improved efficiency of waste paper recycling and control of waste paper quality.
