SOME ASPECTS OF FUZZY DECISION‐MAKING

Abstract

The paper deals with some problems of decision‐making by the use of fuzzy set theory. The application of different operators from a wide class of intersection connectives makes it possible to modelize the process of decision‐making in a very flexible manner. The method of calculation of final non‐fuzzy decision from fuzzy set of decision D is discussed in detail and the problem of the choice of a threshold level presented as appropriate to the intersection operator applied before. The notion of sensitivity of any of intersection operators discussed is introduced and considered in detail.
