Extending fuzzy inference model by both grey relational method and extension theory

摘要

A new extended fuzzy model is proposed in this paper. The newly established extension theory is integrated into the conventional fuzzy system to enhance the reasoning capability. Not only the sample data located at the classical fuzzy set have effect to adjust the mapped membership function, but also the data in the neighboring regions are simultaneously considered. Simulation results from the extended fuzzy model are given and the comparisons with the results from ellipsoidal fuzzy method and other approaches are also made.
