Information fusion of fuzzy numbers has played a vital role in the decision support systems under environment q-rung orthopair set (q-ROFS), which is an effective extension intuitionistic and set. The goals present work are to build family new aggregation operators (AOs) q-ROF apply them MADM problems. First, extended Archimedean copula (EAC) co-copula (EACC) proposed handle information; conseq...

In this paper, we defined the interval form of \(\alpha, \beta\) level set for triangular q-rung orthopair fuzzy (qROPF) number. To obtain a differentiability notion qROPF valued functions, Hukuhara (H-differentiability) and level-wise H-differentiability is defined. Using KKT optimality condition optimization problem with objective function are formulated.

Abstract Despite the importance of cosine and cotangent function- based similarity measures, literature has not provided a satisfactory formulation for case q-rung orthopair fuzzy set (qROFS). This paper criticizes existing attempts in terms respect basic axioms measure strict inclusion relation. In addition, maximum operator-based measures are criticized. Then, new improved, axiomatically supp...

Brain carcinoma is one of the massive dangerous diseases in human body, and certain intellectuals have been affected by them. Additionally, using complex q-rung orthopair fuzzy set, which important, dominant technique to manage indeterminate ambiguous information genuine life troubles. This study aims employ principle variation coefficient similarity measures generalized under sets illustrated ...

Symmetry-related problems can be addressed by means of group theory, and ring theory seen as an extension additive theory. Ring a significant topic in abstract algebra, is currently active diverse range study domains across the disciplines mathematics, theoretical physics coding The ideals vital to rings wide ways. uncertainties present information are well q-rung orthopair fuzzy set (q-ROFS). ...

Hierarchical structures and uncertainty measures are two main aspects in granular computing, approximate reasoning and cognitive process. Typical hesitant fuzzy sets, as a prime extension of fuzzy sets, are more flexible to reflect the hesitance and ambiguity in knowledge representation and decision making. In this paper, we mainly investigate the hierarchical structures and uncertainty measure...

In this paper, by integrating the q-rung orthopair fuzzy set (q-ROFS) with N-soft set, we first propose a (q-ROFNSS). Based on q-ROFNSS, explore weighted average (q-ROFNSWA) operator and geometric (q-ROFNSWG) operator, investigate some properties of q-ROFNSWG including idempotency, monotonicity boundedness. Finally, two kinds multiple-attribute group decision-making (MAGDM) methods based aggreg...

Abstract Pythagorean fuzzy sets (briefly, PFSs) were created as an upgrade to intuitionistic IFSs) which helped address some problems that IFSs couldn’t solve. The definition of q-rung orthopair q-ROFS) is then declared generalize and solve PFS IFS failures. Using the concept PF $$\beta $$ β -neighborhood, Zh...

Abstract The term “ q -Rung orthopair fuzzy sets ( $$q^{r}$$ q r OFSs)” refers to the collection of most differentiated ideas for expressing data in decision-making rules. OFSs can gradually adapt region information by adjusting parameter $$q \ge 1$$ ...

In today’s environment, as the complexity of actual events develops, products become increasingly complicated. As a result, companies should collaborate to integrate disparate technologies while developing product or service. Additionally, collaborating with right supplier helps company increase flexibility, competitiveness, and profitability its goods services. The goal this study is look into...
