Abstract. The authors propose an approach to find numerical characteristics of initial data in fuzzy inference systems. Such characteristics are calculated on the basis of probabilistic estimates and generalization of Bayesian formula for fuzzy events and are called the credibility of fuzzy events.
Keywords: fuzzy set, probability of fuzzy event, system of fuzzy inference systems, credibility.
