Abstract
Fuzzy Set Theory as proposed by L. Zadeh in 1965 is adaptable to different problem structures and well suited to model human evaluation and decision making processes. If uncertainty enters into models, it is classically of the stochastic kind which can properly be modelled by using probability theory. There are other fields, however, in which the description of problems contains uncertainties, in which, however, they are of a different kind than randomness. One of the most important areas of this kind is probably that of human problem solving and decision making: here the human factor enters with all its vaguenesses of perception, of subjectivity, of attitudes of goals and conceptions. To use a modeling language which is dichotomous in this area seems far from adequate.
