This article describes how most frequently uncertainty arises due to vagueness, imprecision,
partial information, etc., are encountered in medical diagnosis. To deal with this type of …

Multi-attribute decision-making (MADM) technique has been widely utilized in many
domains, including management, economics, and other disciplines. It plays a significant role …

Abstract q-rung picture fuzzy sets can handle complex fuzzy and impression information by
changing a parameter q based on the different hesitation degree and yield a flexible …

Fuzziness is inherent in decision data and decision making process. In this paper, interval-
valued intuitionistic fuzzy (IVIF) sets are used to capture fuzziness in multiattribute decision …

Pythagorean fuzzy sets are powerful techniques for modeling vagueness in practice. The
aim of this article is to investigate an effective means to aggregate uncertain information and …

Picture fuzzy set theory developed by Cuong and Kreinovich is an extension of the fuzzy set
theory and intuitionistic fuzzy set theory. In this paper, we proposed a new framework for …

The Bonferroni mean (BM) operator has the advantage of considering interrelationships
between parameters, but it only can deal with crisp values. In recent years, many extended …

The aim of this paper is to give a multi-attribute decision-making (MADM) method for the
interval-valued intuitionistic fuzzy (IVIF) set using the set pair analysis (SPA) theory. IVIF set …

The power Bonferroni mean (PBM) operator can relieve the influence of unreasonable
aggregation values and also capture the interrelationship among the input arguments, which …

The sum of membership and non-membership degrees of the Pythagorean fuzzy set is
greater than one with their square sum less than or equal to one. Thus, as an extension of …
