Linguistic hedges and the generalized modus ponens

In this paper a modification of the generalized modus ponens is presented, namely, rule: if X is bB then Y is cC; fact: X is aB, conclusion: Y is dC where a, b, c, e, and d are linguistic hedges, and B, C are fuzzy sets. The procedure that allows one to evaluate the modifier d is very simple and gives results given in Refs. 15, 18, 26, and 27. Our approach is algebraic‐based and realizes Zadeh's calculus on words by means of Chang's MV algebra. ©1999 John Wiley & Sons, Inc.
