Pythagorean fuzzy set, generalized by Yager, is a new tool to deal with vagueness
considering the membership grade μ μ and non-membership ν ν satisfying the condition μ …

The generalized Heronian mean and geometric Heronian mean operators provide two
aggregation operators that consider the interdependent phenomena among the aggregated …

In this paper, we utilize power aggregation operators to develop some Pythagorean fuzzy
power aggregation operators: Pythagorean fuzzy power average operator, Pythagorean …

In this paper, we investigate the multiple attribute decision making problems with picture
fuzzy information. Then, we utilize arithmetic and geometric operations to develop some …

Pythagorean fuzzy set (PFS) is one of the most successful in terms of representing
comprehensively uncertain and vague information. Considering that the correlation …

In this paper, we investigate the multiple attribute decision making (MADM) problem based
on the arithmetic, geometric aggregation operators and Hamacher operations with picture …

The objective of this paper is to focus on multi-attribute decision-making for interval-valued
intuitionistic fuzzy set environment based on set pair analysis (SPA). For it, the major …

The Maclaurin symmetric mean (MSM) operator is a classical mean type aggregation
operator used in modern information fusion theory, which is suitable to aggregate numerical …

Hesitant fuzzy sets (HFSs), which allow the membership degree of an element to a set
represented by several possible values, can be considered as a powerful tool to express …

In this work, we shall present some novel process to measure the similarity between picture
fuzzy sets. Firstly, we adopt the concept of intuitionistic fuzzy sets, interval-valued …
