perception; fuzzy type theory; approximate reasoning

We present an alternative to the well known Mamdani rule, which we call the perception-based logical deduction. The leading assumption is that fuzzy IF-THEN rules are interpreted as genuine linguistic sentences consisting of the, so called, evaluating linguistic expressions. The latter and sets of fuzzy IF-THEN rules, called linguistic descriptions, are used in derivation of a conclusion.
