This paper focuses on a fuzzy reasoning method based on a generalized If‐Then rule. Firstly, the antecedent and the consequent of an If‐Then rule are considered and expressed as a component of a kind of binary L ‐type fuzzy relation on the product of the universes of discourse and the range of definition for a certain fuzzy attribute. Then a generalized extension principle based on this L ‐type fuzzy relation (FR‐GEP) is constructed. Moreover, the paper gives a detailed description of this generalized If‐Then rule using 20 well‐known common implication operators in the framework of the composition of L ‐type fuzzy relations. Consequently, an L ‐type binary fuzzy reasoning method based on this generalized If‐Then rule is established according to FR‐GEP. © 2002 Wiley Periodicals, Inc.
