Abstract: The fuzzy sets theory offers description for imprecisely formulated dependencies, values of variables, functions, relations and the imprecise values of truth. Knowledge-based systems applied in medicine, economy or in natural sciences require specific knowledge, which is derived from human experts. Knowledge is often expressed in linguistic categories, in a form of a collection of sentences. Mathematical methods proposed in the lecture use both, empirical data and experts’ knowledge to create hierarchical knowledge-based fuzzy models of the tested systems. The probability of fuzzy event is also used to valuate rules in the model. Some exemplary calculations will be presented.
