Fuzzy Reasoning Method Based on Spatial Relationship

Abstract

This paper discusses fuzzy reasoning method by Shu et al. in which the consequence B' for a fuzzy rule A⇒B and a given fuzzy input A' is inferred according to the spatial relationship of fuzzy sets A, A' and B. Especially, the multifold fuzzy reasoning is investigated, and the improvement method for the fuzzy reasoning method is proposed by introducing a scale factor as the parameters characterizing a fuzzy rule.
