Abstract

One of the desirable properties of generalized modus ponens in fuzzy logic is X is A → Y is B X is not A/Y is unknown. From a truth-value viewpoint, unknown can be represented as the interval [0, 1]. However, most existing fuzzy reasoning mechanisms use the truth value 1 to represent 'unknown'. In this paper, we propose a new approach to fuzzy reasoning based on a possible world approach. We show that our approach obtains the desired interval truth value [0, 1] when the antecedent is known to be false. We also compare our approach to Baldwin's and Godo's approaches and discuss the impact of the proposed approach to other desired properties of generalized modus ponens and generalized modus tollens.
