Circular n,m-rung orthopair fuzzy sets and their applications in multicriteria decision-making

Demonstratio Mathematica
The circular Pythagorean fuzzy set is an expansion of the circular intuitionistic fuzzy set (CIFS), in which each component is represented by a circle.

Optimistic multi-granulation roughness of intuitionistic fuzzy ideals based on soft relations over dual universes

Heliyon
The major point of proposed work is to study optimistic multi-granulation roughness of intuitionistic fuzzy ideals by using soft relations that is free from all the complications that challenged by many researchers.

Higher-order circular intuitionistic fuzzy time series forecasting methodology: Application of stock change index

Demonstratio Mathematica
This article presents a higher-order circular intuitionistic fuzzy time series forecasting method for predicting the stock change index, which is shown to be an improvement over traditional time series forecasting methods.

A note on the fuzzy Xor

Annales Mathematicae Silesianae
In this paper we will try to answer what conditions must be met by the fuzzy Xor to be used for cryptographic purposes. We will also show that defining the fuzzy Xor using other fuzzy connectives is not suitable for this purpose.

Decision support system for selection of the appropriate tool of artificial intelligence using Diophantine spherical fuzzy normal interval-valued set

Journal of Taibah University for Science
Modern society employs an increasing number of robots, notably service robots. Robots will be able to handle everyday objects with simplicity, but only if they are collaborated with a planning and decision-making (DM) strategy that allows them to very ...

Fuzzy logics as the logics of chains

, 2008
The paper proposes a formal delimitation of the class of ‘fuzzy logics ’ and answers some objections that can be raised against the definition; the focus is put on informal and motivational aspects of the problem.

Some results in the level sets of some bipolar fuzzy relations

Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica
In this paper, some properties of a BPFR were studied. Also, level sets of BPFRs were studied with their properties. Some results were given and, in some cases, examples and counter-examples were constructed. In particular, we have shown that if a BPFR Q

Some properties of residuated lattices

, 2003
We investigate some (universal algebraic) properties of residuated lattices -algebras which play the role of structures of truth values of various systems of fuzzy logic.
