To design and manage uncertainty for fuzzifier m, we extend a pattern set to interval type-2 fuzzy sets using two fuzzifiers m1 and m2 which creates a footprint of uncertainty (FOU) for the fuzzifier m. Then, we incorporate this interval type-2 fuzzy set in...

As control using type-2 fuzzy sets represents a new generation of fuzzy controllers in mobile robotic issue, it is interesting to present the performances that can offer type-2 fuzzy sets by regards to type-1 fuzzy sets. The paper presented deep and new comparisons between the two sides of ...
Then, interval type-2 fuzzy sets (IT2 FSs) and linguistic variables are employed to handle the uncertainties, and the TOPSIS method is improved using IT2 FSs to obtain an optimal alternative for a LGDM problem. Next, decision weights are computed based on the centrality of the SNA, and ...
An important problem in working with fuzzy sets is the correct construction of the membership functions that represent the objects of the system. Different experts construct different membership functions to represent the same object. In this paper, we construct an interval type-2 fuzzy set (IT2FS...
model. Then the type-2 fuzzy T-S model is obtained from the type-1 model through unconstrained optimization where the Nelder-Mead Simplex method is utilized.Finally, the results of the experiment prove the efficiency of the proposed algorithm. Introduction • Type fuzzy sets, originally ...
While excessive arithmetic operations are needed with type-2 fuzzy sets with respect to type-1's, type-2 fuzzy sets generalize type-1 fuzzy sets and systems so that more uncertainty for defining membership functions can be handled. A type-2 fuzzy set lets us incorporate the uncertainty of ...
It has been widely used in ranking of multi alternatives with respect to multi criteria with the superiority of fuzzy set type-1. In this paper based on the interval type-2 fuzzy sets, we introduce a new method of fuzzy TOPSIS for handling fuzzy ranking multi criteria group/individual decisio...
2. First, the definitions and descriptions of extensions of fuzzy sets, such as Intuitionistic fuzzy Sets, L-fuzzy sets and L-IFS, interval-valued fuzzy sets and IVIFS and Vague sets, etc. 首先给出了模糊集理论的各种拓展,如直觉模糊集、L 模糊集与L 直觉模糊集、区间值模糊集与区间值直觉模糊...
