Y. Qian et Pjc. Tessier, APPLICATION OF FUZZY RELATIONAL MODELING TO INDUSTRIAL-PRODUCT QUALITY-CONTROL, Chemical engineering & technology, 18(5), 1995, pp. 330-336
Industrial product quality control is a typical mathematical programmi
ng and optimization problem. Unfortunately, complete and precise model
s are not always available for many industrial processes. A fuzzy rela
tion modelling approach is proposed to describe approximate relationsh
ips among system variables and reconcile empirical equations. Symmetri
c fuzzy decision-making is transformed into a non-linear function maxi
mization problem. The approach is applied to optimization of a wood ch
ip refining process. It is used either to improve pulp quality within
the refiner operation range, or to reduce operation costs while mainta
ining an acceptable pulp quality.
