The relationship of three difference operations for fuzzy numbers to three kinds of derivative.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p5897-5911. 15p.

Abstract: The difference operation for fuzzy number is an essential concept for the fuzzy set theory. There are several differences proposed: generalized difference, generalized Hukuhara difference and granule difference. Based on these differences, generalized ...

Fuzzy preorder based fuzzy rough sets using multiplication and division.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p5443-5451. 9p.

Authors:

Abstract: By a fuzzy preorder, it means a (0, 1]-binary relation on a nonempty set which is self-reflective and transitive. For a fuzzy preorder on a universe, this paper constructs a kind of fuzzy rough set model based on the multiplication and division of real...

Three-way decision theory based on interval type-2 fuzzy linguistic term sets.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 4, p3911-3932. 22p.

Abstract: This study examines decision theory based on interval type-2 fuzzy sets with linguistic information for the three-way decision approach by addressing the challenge of uncertainty for information analysis and fusion in subjective decision-making process...

Linguistic q-rung orthopair fuzzy multiple-attribute group decision making based on the grey similarity degree and PROMETHEE II method.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p6607-6625. 19p.

Abstract: Linguistic q-rung orthopair fuzzy numbers (Lq-ROFNs) are an effective tool for representing fuzzy linguistic information, and they can obtain a wider expression scope than linguistic intuitionistic fuzzy numbers and linguistic Pythagorean fuzzy numbers...

An algorithm for identifying reference signals under the environment of complex fuzzy sets.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p6521-6548. 28p.

Abstract: In this paper, we have discussed some new operations and results of set theory for complex fuzzy sets (CFSs). Moreover, we developed the basic results of CFSs under the basic operations such as complex fuzzy simple difference, bounded sum, bounded diff...

Novel similarity measures for T-spherical fuzzy sets and their applications in pattern recognition and clustering.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p6321-6331. 11p.

Abstract: T-spherical fuzzy sets, the direct extension of fuzzy sets, intuitionistic fuzzy sets and picture fuzzy sets are examined in this composition, and a mathematical examination among them is set up. A T-spherical fuzzy set can demonstrate phenomenon like ...

Covering-based generalized variable precision fuzzy rough set.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p6175-6187. 13p.

Authors:

Abstract: Zhan and Jiang defined covering-based compact and loose variable precision fuzzy rough set models. Soon after, they proposed a reflexive fuzzy β-neighborhood operator and defined a covering-based generalized variable precision fuzzy rough set. Based on...

Probabilistic hesitant fuzzy multi-attribute decision-making method based on improved distance measurement.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p5953-5964. 12p.

Abstract: In order to solve the problem of multi-attribute decision-making with unknown weights under probabilistic hesitant fuzzy information, considering the shortcomings of the existing probabilistic hesitant fuzzy distance measure, such as weak distinguishin...

Picture fuzzy Z-linguistic set and its application in multiple attribute group decision-making.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 5, p5997-6011. 15p.

Abstract: Picture fuzzy linguistic set is a vital solution to express complex and uncertain information, which has been applied in multi-attribute group decision-making (MAGDM). However, the credibility of decision-making information is unconsidered, which may g...

A new integrated methodology for constructing linguistic pythagorean fuzzy statements for decision making problems.

Publication Type: Academic Journal

Source(s): Journal of Intelligent & Fuzzy Systems. 2022, Vol. 43 Issue 4, p4883-4894. 12p.

Abstract: As a combining concept of Pythagorean fuzzy sets (PFSs) and linguistic fuzzy sets (FSs), linguistic PFSs (LPFSs) has been suggested in the literature to deal with the uncertain and inconsistent information in multi-criteria decision making (MCDM) proce...
