Fuzzy numbers intuitionistic fuzzy descriptor systems
Information Sciences, 2018The study is concerned with intuitionistic fuzzy control and brings an idea of fuzzy numeric intuitionistic fuzzy sets (FNIFS) regarded as generic building components of fuzzy models. The definition of this concept is provided along with some comparative analysis involving other types of information granules.

Notes on triangular intuitionistic fuzzy numbers
International Journal of Mathematics in Operational Research, 2013The notion of triangular fuzzy number is put forward on the basis of intuitionistic fuzzy sense. The basic algebra and some non-linear operations of triangular intuitionistic fuzzy numbers (TIFNs) are devised. The average ranking index is introduced to find out order relations between two TIFNs.

An approximation method of intuitionistic fuzzy numbers
Journal of Intelligent & Fuzzy Systems, 2016A method of approximating intuitionistic fuzzy numbers by trapezoidal intuitionistic fuzzy numbers with respect to a well-known metric is studied in this paper. Firstly, the representations of extended trapezoidal intuitionistic approximations of intuitionistic fuzzy numbers are discussed.

Ranking of trapezoidal intuitionistic fuzzy numbers
2012 12th International Conference on Intelligent Systems Design and Applications (ISDA), 2012Techniques for ranking simple fuzzy numbers are abundant in nature. However, we lack effective methods for ranking intuitionistic fuzzy numbers(IFN). The aim of this paper is to introduce a new ranking procedure for trapezoidal intuitionistic fuzzy number(TRIFN). To serve the purpose, the value and ambiguity index of TRIFNs have been defined.

RANKING-INTUITIONISTIC FUZZY NUMBERS
International Journal of Uncertainty, Fuzziness and Knowledge-Based Systems, 2004Intuitionistic fuzzy sets are a generalization of ordinary fuzzy sets which are characterized by a membership function and a non-membership function. In this paper we consider the problem of ranking a set of intuitionistic fuzzy numbers. We adopt a statistical viewpoint and interpret each intuitionistic fuzzy number as an ensemble of ordinary fuzzy ...

Intuitionistic Fuzzy Z-numbers
2020Fuzzy sets and its extensions are widely used to determine membership of an element using different functions to decrease the effect of uncertainty. In this paper, intuitionistic fuzzy Z-numbers that are a new extension of fuzzy sets are proposed for the first time. First, fuzzy Z-numbers and intuitionistic fuzzy numbers are determined as preliminaries.

IEEE Transactions on Fuzzy Systems, 2016
In this paper, we propose a method to construct homeomorphisms from the interior of intuitionistic fuzzy interpretation triangle to the complex plane. Based on such homeomorphisms, we define concepts of pure intuitionistic fuzzy sets and pure intuitionistic fuzzy numbers, and obtain some properties of these new concepts.

Models for software quality evaluation with fuzzy number intuitionistic fuzzy information
Journal of Intelligent & Fuzzy Systems, 2016Software is omnipresent in our daily lives. Delivering quality software on schedule and in budget has become the challenge for most companies. As software size and complexity are increasing at a geometric rate, assuring software quality is becoming more difficult.

New ranking methods of intuitionistic fuzzy numbers and Pythagorean fuzzy numbers
2020 Chinese Control And Decision Conference (CCDC), 2020The ranking method can distinguish the size of intuitionistic fuzzy numbers and Pythagorean fuzzy numbers, and plays an important role in the application of intuitionistic fuzzy sets and Pythagorean fuzzy sets. Based on the summary of classic ranking methods, this paper proposes some new ranking methods.
