Toward a restructuring of the foundations of fuzzy logic (FL)

The proposed restructuring of fuzzy logic (FL) is centred on two basic issues: (a) identification of the principal facets of FL and its core concepts; and (b) introduction of the concept of the generalization group and its employment for generation of rules of inference or, equivalently, rules of constraint propagation. The proposed restructuring has three objectives. First, to clarify and solidify the foundations of fuzzy logic; second to make more transparent the links between fuzzy logic and other methodologies; and third, to suggest alternative ways for further development of fuzzy logic and its applications.
