摘要：
General type-2 fuzzy logic systems have received wide concerns in current academic subject. Type-reduction is the kernel module for the systems. This paper shows the interpretations for the beginning of Karnik-Mendel (KM) algorithms. According to the famous numerical integration technique, the weighting approaches of enhanced Karnik-Mendel (EKM) algorithms are put forward. Then, the sensible beginning weighted enhanced Karnik-Mendel (SBWEKM) algorithms are put forward to perform the centroid type-reduction. Compared with the EKM algorithms, WEKM algorithms and SBEKM algorithms, this approach helps to improve both the absolute errors and convergence speeds as shown in four computer simulation experiments.
