Interval-valued fuzzy reasoning with interval-valued fuzzy truth

摘要

In this paper, a new similarity measure between interval-valued fuzzy sets (IvFSs) is presented. By using the proposed measure, we can formulate a new method for interval-valued fuzzy (IvF) reasoning with interval-valued fuzzy truth. At last, a weighted IvF reasoning method with IvF truth is also developed by considering the weight factor of each variable in the antecedent of IvF rule contributing to the consequent.
