A new and efficient method for the type-2 meet operation

Type-2 fuzzy logic systems require considerable processing resources to arrive at a conclusion. This paper shows how this can be significantly reduced, focusing specifically on the meet operation. We show how to eliminate large amounts of redundancy from the operation and then present a geometric method that is even more efficient. Results from initial experiments into performance increases are given. These results show that our method can give a significant increase in performance for certain types of secondary memberships.
