Abstract :
Karnik-Mendel (KM) algorithms type reduction are commonly used in the centroid computation of interval type-2 fuzzy logic systems (IT2 FLSs). Some properties and improvements of the KM algorithms have be proposed. This paper proposed a new iteration formula for the centroid computation of interval type-2 fuzzy sets, which is faster than the current computation methods and can be used as a direct method for the centroid computation of interval type-2 fuzzy sets.
