Due to the complexity and uncertainty of objective things, interval-valued intuitionistic fuzzy (I-
VIF) numbers are often used to describe the attribute values in multiple-attribute decision …

This paper develops some new decision making methods for multi-attribute decision making
(MADM) problems, in which the attribute weights take the form of crisp numbers, and …

Interval-valued intuitionistic fuzzy numbers (IVIFNs) are usually utilized in multi-attribute
decision making problems, providing an accurate description of incomplete and uncertain …

In this paper, we propose a new multiattribute decision making (MADM) method based on
probability density functions (PDFs) and the variances and standard deviations of the largest …

This paper puts forward a new ranking method for multiple attribute decision‐making
problems based on interval‐valued intuitionistic fuzzy set (IIFS) theory. First, the composed …

In this paper, we propose a new multiattribute decision making (MADM) method based on
the U-quadratic distribution of intervals and the transformed matrix of the decision matrix …

With respect to interval-valued intuitionistic fuzzy multiple attribute decision making
problems with preference information on alternatives and unknown weight information …

In this paper, we propose a new multiattribute decision making method based on converted
decision matrices, probability density functions and interval-valued intuitionist fuzzy values …

This paper proposes the improved intuitionistic fuzzy Einstein weighted averaging (IIFEWA)
operator of intuitionistic fuzzy values (IFVs). The proposed IIFEWA operator can overcome …
