OPTIMIZATION OF LATEX-COAT DRYING (REFERRED TO NET MATERIALS) APPLYING FUZZY-SET THEORY

Mathematical modeling and optimization of film-coat drying are discuss ed. With reference to drying of fishnet materials two approaches to th e solution of this aspect are examined in a situation where the experi mental data are incomprehensive and inaccurate. One approach entails a pplication of experiment design techniques to derive regressive equati ons. Further, the search for optimal parameters reduces to the solutio n of a normal optimization problem with the first and second types of constraints. The purpose of the second approach is to establish a qual itative link between the drying parameters on the one hand and the pro perties of the goods on the other. These properties are impossible to measure quantitatively, so the method of appraisal by experts is appli ed. Thus, what we have here is a multicriterial problem of finding a s olution in ill-defined situations. It is proposed to be solved by appl ying a body of mathematics of the fuzzy-set theory.
