Abstract
The paper deals with a model of decision-making given in a form of a fuzzy relational equation with relationships between imprecisely defined goals and constraints modelled by means of a fuzzy relation. The usefulness of the model and its novelty is clearly pointed out. Some basic problems concerned, e.g. with a construction of the relation of the model and ordering of goals and constraints with respect to their importance (viz. their influence on a fuzzy decision), are also discussed in a detailed manner.
