An nth power root fuzzy set is a useful extension of for expressing uncertain data. Because their wider range showing membership grades, sets can cover more ambiguous situations than intuitionistic sets. In this article, we present several novel operations on sets, as well various features. Besides, develop new weighted aggregated operator, namely, average (nPR-FWPA) over to deal with choice in...

Paper aims Presents a new group decision approach for circular business models (CBMs) prioritization based on economy (CE) principles and indicators. Originality It was not found in the literature quantitative approaches to indicate which CBMs can be prioritized towards CE implementation. Research method Fuzzy AHP is applied calculate weights of principles. TOPSIS used rank CBMs. A pilot applic...

Recent research has recognised that multicriteria decision making (MCDM) should take account of uncertainty, risk and confidence. This paper takes this research forward by using linguistic variables and triangular fuzzy numbers to model the decision maker’s (DM) risk and confidence attitudes in order to define a more complete MCDM solution. To illustrate the computation process and demonstrate ...

Intuitionistic fuzzy sets as proposed by Atanassov, have gained much attention from past and latter researchers for applications in various fields. Similarity measures between intuitionistic fuzzy sets were developed afterwards. However, it does not cater the conflicting behavior of each element evaluated. We therefore made some modification to the similarity measure of IFS by considering confl...

As a generalization of fuzzy sets and intuitionistic fuzzy sets, neutrosophic sets have been developed to represent uncertain, imprecise, incomplete, and inconsistent information existing in the real world. And interval neutrosophic sets (INSs) have been proposed exactly to address issues with a set of numbers in the real unit interval, not just a specific number. However, there are fewer relia...

Decision-making techniques are used to select the "best" alternatives under multiple and often conflicting criteria. Multicriteria decision making (MCDM) necessitates to incorporate uncertainties in the decision-making process. The major thrust of this article is to extend the framework proposed by Yager for multiple decisionmakers and fuzzy utilities (payoffs). In addition, the concept of expe...
