This study presented a comprehensive multi-attribute decision-making framework founded on bipolar complex intuitionistic fuzzy numbers (BCIFNs) to enhance decision reliability under conditions of uncertainty and dual (positive-negative) evaluation. First, new operational laws were formulated for BCIFNs, providing a rigorous mathematical foundation for developing two aggregation mechanisms: the bipolar complex intuitionistic fuzzy weighted average (BCIFWA) and the bipolar complex intuitionistic fuzzy weighted geometric (BCIFWG) operators. These operators were systematically derived to ensure logical consistency, robustness, and suitability for handling uncertain, imprecise, and bipolar information. Building on these operators, a structured multi-attribute decision- making methodology was proposed to evaluate alternatives across multiple conflicting attributes. The approach was applied to a real-world case study on waste-to-energy (WtE) and circular economy solutions, focusing on identifying the most sustainable strategy for integrated waste management. Six WtE alternatives were assessed across environmental, economic, and social dimensions. The analysis revealed that incineration with energy recovery emerged as the most effective solution, offering a balance of high energy recovery, substantial waste volume reduction, and technological reliability. A comparative analysis with existing fuzzy decision-making methods highlighted the superior ranking stability and adaptability of the proposed BCIFWA and BCIFWG operators, particularly in complex evaluation scenarios with bipolar uncertainty. The results demonstrated the framework’s flexibility, scalability, and enhanced decision precision, contributing to both the theoretical development of fuzzy multi-attribute decision-making and the practical advancement of sustainable waste management and circular economy strategies.

Innovative approaches to (n,m)-rung orthopair fuzzy graphs for enhancing performance measures

Graph construction is a powerful tool for solving complex problems across vari- ous fields of computer science and computational intelligence. When dealing with uncertainty, fuzzy graph structures are preferred over crisp graph structures, as they effectively represent the inherent uncertainty within a network. To better cap- ture vague and imprecise concepts, the (n,m)-rung orthopair fuzzy set serves as a highly effective framework, as its models provide greater flexibility than other fuzzy models when handling human judgment data. In this paper, we introduce a new framework, referred to as (n,m)-rung orthopair fuzzy graphs ((n,m)-ROFGs), by integrating the concept of graphs with (n,m)-rung orthopair fuzzy sets. The key advantage of this framework is that it meets the demands of certain applica- tions that cannot be effectively modeled using previous approaches to handling uncertainty, as they either require equal degrees of uncertainty (such as IFSs, PFSs, and q-ROFSs) or impose restrictions on the powers of uncertainty degrees through fixed parameter values n and m( as in (2,1)-FSs and (3,2)-FSs). We start by in- troducing the degree and whole degree of a vertex in (n,m)-ROFGs, and illustrate their significance using road networks. Understanding the degree and whole degree of a vertex also provides insight into the characteristics of product operations on (n,m)-ROFGs. Building on this, we define the strong product and ∗-product as product operations on (n,m)-ROFGs. These operations become particularly useful when dealing with a large number of (n,m)-ROFGs. We also introduce the concept of vertex degree and whole degree in the strong product and ∗-product, and estab- lish general theorems concerning the degree and whole degree of (n,m)-ROFGs under the proposed product operations, and provide several numerical examples to illustrate the introduced concepts. Furthermore, we explore an application of the degree and whole degree of the ∗-product of two (n,m)-ROFGs in multi-criteria decision-making concerning the selection of the most likely team to compete in games and using optimal performance measures. Finally, we make comparisons to highlight the shortcomings of previous techniques in modeling certain practical cases that are effectively addressed by our approach, as well as we discuss the mi- nor limitations of the proposed method associated with excessively large values of n and m that can generally be mitigated by selecting moderate settings that better reflect typical decision-making contexts.

Complex nth power root fuzzy sets: Theory, and applications for multi-attribute decision making in uncertain environments

The newly introduced n$^{th}$ power root fuzzy set is a useful tool for expressing ambiguity... See more

The newly introduced n$^{th}$ power root fuzzy set is a useful tool for expressing ambiguity and vagueness. It has an improved ability to manage uncertain situations compared to intuitionistic fuzzy set and Pythagorean fuzzy set theories, making n$^{th}$ power root fuzzy sets applicable in various everyday decision-making contexts. The notions of n$^{th}$ power root fuzzy sets and complex fuzzy sets are integrated in this study to offer complex n$^{th}$ power root fuzzy sets (CnPR-FSs), explaining its fundamental ideas and useful applications. The proposed CnPR-FS integrates the advantages of n$^{th}$ power root fuzzy set and captures both quantitative and qualitative analyses of decision-makers. It is shown that CnPR-FSs are a crucial tool that can describe uncertain data better than complex intuitionistic fuzzy sets and complex Pythagorean fuzzy sets. A key characteristic of CnPR-FSs is a constraint that guarantees the summation of the nth power of the real (and imaginary) part of the complex-valued membership degree and the 1/n power of the real (and imaginary) part of the complex-valued non-membership degree to be equal to or less than one. This allows for a broader representation of uncertain information. The study also explores the creation of customized comparison techniques, accuracy functions, and scoring functions for two complex n$^{th}$ power root fuzzy numbers. Furthermore, it investigates novel aggregation operators by providing in-depth descriptions of their characteristics, such as complex n$^{th}$ power root fuzzy weighted averaging (CnPR-FWA) as well as complex n$^{th}$ power root fuzzy weighted geometric (CnPR-FWG) operators based on CnPR-FSs. Through an in-depth analysis, this paper aims to determine the selection of the most suitable caterer and optimal venue for corporate events. The study's outcomes highlight the suggested method's effectiveness and practical application as compared to other approaches, providing insight into its practical applicability and efficacy.

Circular n,m-rung orthopair fuzzy sets and their applications in multicriteria decision-making

The circular Pythagorean fuzzy set is an expansion of the circular intuitionistic fuzzy set (CIFS), in which each component is represented by a circle. Nevertheless, even though CIFS improves the intuitionistic fuzzy set representation, it is still restricted to the inflexible intuitionistic fuzzy interpretation triangle (IFIT) space, where the square sum of membership and nonmembership in a circular Pythagorean fuzzy environment and the sum of membership and nonmembership in a circular intuitionistic fuzzy environment cannot exceed one. To overcome this restriction, we provide a fresh extension of the CIFS called the circular n,m-rung orthopair fuzzy set (Cn,m-ROFS), which allows the IFIT region to be expanded or contracted while maintaining the features of CIFS. Consequently, decision makers can assess items over a wider and more flexible range when using a Cn,m-ROFS, allowing for the making of more delicate decisions. In addition, we define several basic algebraic and arithmetic operations on Cn,m-ROFS, such as intersection, union, multiplication, addition, and scalar multiplication, and we discuss their key characteristics together with some of the known relations over Cn,m-ROFS. In addition, we present and study the new circular n,m-rung orthopair fuzzy weighted average/geometric aggregation operators and their properties. Further, a strategy for resolving multicriteria decision-making problems in a Cn,m-ROF environment is provided. The suggested strategy is tested on two situations: the best teacher selection problem and the best school selection problem. To confirm and illustrate the efficacy of the suggested methodology, a comparative analysis with the intuitionistic fuzzy weighted average, intuitionistic fuzzy weighted geometric, q-rung orthopair fuzzy weighted averaging, q-rung orthopair fuzzy geometric averaging, circular PFWAmax , and circular PFWAmin operators approaches is also carried out. Ultimately, in the final section, there are discussions and ideas for future research.

The recently introduced n,m-rung orthopair fuzzy set emerges as a valuable means to articulate ambiguity and vagueness. With its enhanced capacity to handle uncertain scenarios in contrast to q-rung orthopair fuzzy set theories, n,m-rung orthopair fuzzy sets find diverse applications in everyday decision-making processes. This study presents a fresh approach to handling ambiguity and uncertainty in multi-attribute decision-making by introducing a novel tool termed as complex n,m-rung orthopair fuzzy set (Cn,m-ROFS). The proposed Cn,m-ROFS integrates the advantages of n,m-rung orthopair fuzzy set and captures both quantitative and qualitative analyses of decision-makers. This model represents a significant advancement over complex q-rung orthopair fuzzy sets and offers a fruitful avenue for addressing such complexities in decision-making processes. Moreover, the fundamental laws of Cn,m-ROFSs are outlined. Additionally, the paper develops specialized score functions, accuracy functions, and comparison methods tailored for two complex n,m-rung orthopair fuzzy numbers. Furthermore, it explores novel aggregation operators such as complex n,m-rung orthopair fuzzy weighted averaging (Cn,m-ROFWA) and complex n,m-rung orthopair fuzzy weighted geometric (Cn,m-ROFWG) oper- ators based on Cn,m-ROFSs, providing comprehensive descriptions of their properties. Utilizing these operators, a new method for multi-attribute decision making problems within the complex n,m-rung orthopair fuzzy set theory framework is presented and validated through practical examples. The paper’s findings underscore the effectiveness and practical applicability of the proposed method compared to existing methodologies, shedding light on its practical utility and efficacy.

A useful tool for expressing fuzziness and uncertainty is the recently developed n,m-rung orthopair fuzzy set (n,m-ROFS). Due to their superior ability to manage uncertain situations compared to theories of q-rung orthopair fuzzy sets, the n,m-rung orthopair fuzzy sets have variety of applications in decision-making in daily life. To deal with ambiguity and unreliability in multi-attribute group decision-making, this study introduces a novel tool called kn m-rung picture fuzzy set (kn m-RPFS). The suggested knm-RPFS incorporates all of the benefits of n,m-ROFS and represents both the quantitative and qualitative analyses of the decision-makers. The presented model is a fruitful advancement of the q-rung picture fuzzy set (q-RPFS). Furthermore,numerous of its key notions, including as complement, intersection, and union are explained and illustrated with instances. In many decision-making situations, the main benefit of knm-rung picture fuzzy sets is the ability to express more uncertainty than q-rung picture fuzzy sets. Then, along with their numerous features, we discover the basic set of operations for the kn m-rung picture fuzzy sets. Importantly, we present a novel operator, knm-rung picture fuzzy weighted power average (kn m-RPFWPA) over knm-rung picture fuzzy sets, and use it to multi-attribute decision-making issues for evaluating alternatives with kn m-rung picture fuzzy information. Additionally, we use this operator to pinpoint the countries with the highest expat living standards and demonstrate how to choose the best option by comparing aggregate findings and applying score values. Finally, we compare the outcomes of the q-RPFEWA, SFWG, PFDWA, SFDWA, and SFWA operators to those of the kn m-RPFWPA operator.

Multi-criteria decision-making based on similarity measures on interval-valued bipolar n,m-rung orthopair fuzzy sets

Since intuitionistic and Pythagorean fuzzy sets have not always worked properly in real-life situations when dealing with high levels of uncertainty, the theory of q-rung orthopair fuzzy sets has appeared as a key component of many mathematical hybrid decision-making models for dealing with these difficult situations. Following that, the n,m-rung orthopair fuzzy set theory created as a fresh mathematical tool for handling uncertainty in a variety of applications. The purpose of the n,m-rung orthopair fuzzy sets was to promote mathematical tractability of uncertain data from broadly applicable real-world decision-making situations. In this regard, n,m-rung orthopair fuzzy sets outperform intuitionistic, Pythagorean, and q-rung orthopair fuzzy sets in terms of flexibility and dependability. The situations can be handled more successfully employing bipolar fuzzy sets and its extensions, enabling decisions to be more accurate. The aim of this study is to greatly improve decision-makers' ability to gather knowledge across a wider variety of contexts. In this paper, a new tool called the interval-valued bipolar n,m-rung orthopair fuzzy set (IVBn,m-ROFS) is put forth as a solution to the imprecision and haziness that exist in practical applications. This suggested set completely involve both quantitative and qualitative evaluations and make use of the n,m-rung orthopair fuzzy set to its fullest extent. The model designed is an effective extension of interval-valued bipolar q-rung orthopair fuzzy set (IVBq-ROFS). Additionally, the proposed IVBn,m-ROFS technique essential properties, such as intersection, union, complement, and subset are studied, and numerical examples are given to support their validity. Furthermore, we address several popular similarity measures that are present on the interval-valued bipolar n,m-rung orthopair fuzzy set. The indicated similarity measures have the significant benefit of taking into account the relationships between interval-valued bipolar n,m-rung orthopair fuzzy numbers. Moreover, in order to select the best supplier selection in supply chain management and analyze its acquired consequences, we create a multi-criteria decision-making algorithm that is based on the recommended similarity measures. Finally, we evaluate the advantages and limitations of the novel methodologies in comparison to some of the existing similarity measures based on fuzzy extensions.

The n,m-rung orthopair fuzzy set theory has appeared as a fresh mathematical tool for dealing with uncertainty in several fields of the real world. The n,m-rung orthopair fuzzy sets were introduced to make uncertain data from broadly applicable real-world decision-making scenarios tractable analytically. In this regard, n,m-rung orthopair fuzzy sets outperform intuitionistic, Pythagorean, Fermatean, and q-rung orthopair fuzzy sets in terms of flexibility and dependability. Bipolar fuzzy sets are useful tools for handling fuzziness and bipolarity. The bipolar n,m-rung orthopair fuzzy set (Bn,m-ROFS) model is presented in this study as a generic extension of two powerful existing models, namely the bipolar intuitionistic fuzzy set and the bipolar Pythagorean fuzzy set models. This suggested set completely reflects both quantitative and qualitative evaluations and fully exploits the n,m-rung orthopair fuzzy set. Moreover, subset, equal, complement, inter- section, and union are some key characteristics of the proposed Bn,m-ROFS model that are examined along with numerical examples. Additionally, certain fundamental operations are established here, including the bipolar n,m-rung orthopair fuzzy weighted average operator and the bipolar n,m-rung orthopair fuzzy weighted geometric operator. Furthermore, a Bn,m- ROFS application is investigated to handle various multiattribute decision-making situations, such as the choice of the best manager. The suggested methodology is backed up by an algorithm. Finally, the comparison of the indicated hybrid model with a known model, such as the bipolar Pythagorean fuzzy set, is offered.

A significant addition to fuzzy set theory for expressing uncertain data is an n,m-th power root fuzzy set. Compared to the nth power root, Fermatean, Pythagorean, and intuitionistic fuzzy sets, n,m-th power root fuzzy sets can cover more uncertain situations due to their greater range of displayed membership grades. When discussing the symmetry between two or more objects, the innovative concept of an n,m-th power root fuzzy set over dual universes is more flexible than the current notion of an intuitionistic fuzzy set, a Pythagorean fuzzy set, and a nth power root fuzzy set. In this study, we demonstrate a number of additional operations on n,m-th power root fuzzy sets along with a number of their special aspects. Additionally, to deal with choice information, we create a novel weighted aggregated operator called the n,m-th power root fuzzy weighted power average (FWPAn m) across n,m-th power root fuzzy sets and demonstrate some of its fundamental features. To rank n,m-th power root fuzzy sets, we also define the score and accuracy functions. Moreover, we use this operator to identify the countries with the best standards of living and show how we can select the best option by contrasting aggregate results using score values. Finally, we contrast the results of the FWPAnm operator with the square-root fuzzy weighted power average (SR-FWPA), the nth power root fuzzy weighted power average (nPR-FWPA), the Fermatean fuzzy weighted power average (FFWPA), and the n,m-rung orthopair fuzzy weighted power average (n,m-ROFWPA) operators.

In many practical situations, the theory of q-rung orthopair fuzzy sets has proven to be a more effective tool for handling high levels of uncertainty than intuitionistic, Pythagorean, and Fermatean fuzzy sets; as a result, it is a fundamental part of many mathematicalhybriddecision-makingmodelsforhandlingsuchchallengingdecisivesituations.Thefuzzyparameterizedsoft sets and their extensions are more effective at handling situations where some of the parameters are strongly preferred over others, which allows for more precise decision-making. Similar to this, soft expert sets, as an effective approach, offer the capability of taking into account many experts’ opinions in one place for multiattribute group decision-making situations. The goal of this study is to substantially improve decision-makers’ capacity for collecting their judgment over a wider range of situations. To accomplish this, we present the idea of the n,m-rung orthopair fuzzy soft expert set (n,m-ROFSES) model by combining n,m-rung orthopair fuzzy sets and soft expert sets in order to handle more generalized information. The created model is a successful extension of fuzzy parameterized q-rung orthopair fuzzy soft expert sets (FPqROFSESs). In addition, several of its fundamental concepts, such as subset, complement, union, and intersection are discussed and demonstrated with examples. Due to its benefits over other warm production methods and the world’s rapidly expanding population, heating technology is having an ever-growing global influence. As a result of the increased demand for heating systems, numerous new manufacturers have emerged. Choosing the best technology solution is a difficult decision for suppliers or sale dealers. In order to tackle these issues, we offer a multi-criteria group decision-making algorithm whose authenticity and efficacy are carefully verified. We investigate the use of this approach in reality, that is, the selection of a suitable brand of heating system. At last, a comparison of the initiated model with some existing approaches is presented to verify its advantages over them.

An nth power root fuzzy set is a useful extension of a fuzzy set for expressing uncertain data. Because of their wider range of showing membership grades, nth power root fuzzy sets can cover more ambiguous situations than intuitionistic fuzzy sets. In this article, we present several novel operations on nth power root fuzzy sets, as well as their various features. Besides, we develop a new weighted aggregated operator, namely, nth power root fuzzy weighted power average (nPR-FWPA) over nth power root fuzzy sets to deal with choice information and show some of their basic properties. In addition, we defne a scoring function for nth power root fuzzy sets ranking. Furthermore, we use this operator to determine the optimal location for constructing a home and demonstrate how we may choose the best alternative by comparing aggregate outputs using score values. Finally, we compare the nPR-FWPA operator outcomes to those of other well-known operators.

One of the most helpful fuzzy set extensions for dealing with information uncertainties is an n th power root fuzzy set. In light of this, in this paper, we define an n,m th power root fuzzy set, which is a new type of fuzzy set extension and introduce their relationship with n-rung orthopair fuzzy set, n th power root fuzzy set and n,m-rung orthopair fuzzy set. There is a symmetry between the values of this membership and non-membership functions. To broaden the scope of the decision-making problems, any power function scales are used here. When disputing the symmetry between two or more objects, the innovative concept of an n,mth power root fuzzy set over dual universes is more flexible than the current notion of an intuitionistic fuzzy set, as well as Pythagorean fuzzy set.

A q-rung orthopair fuzzy set is one of the effective generalizations of fuzzy set for dealing with uncertainties in information. Under this environment, in this study, we define a new type of extensions of fuzzy sets called n,m-rung orthopair fuzzy sets and investigate their relationship with Fermatean fuzzy sets, Pythagorean fuzzy sets and intuitionistic fuzzy sets. The n,m-rung orthopair fuzzy sets can supply with more doubtful circumstances than Fermatean fuzzy sets, Pythagorean fuzzy sets and intuitionistic fuzzy sets because of their larger range of depicting the membership grades. There is a symmetry between the values of this membership function and non-membership function. Here, any power function scales are utilized to widen the scope of the decision-making problems. In addition, the novel notion of an n,m-rung orthopair fuzzy set through double universes is more flexible when debating the symmetry between two or more objects that are better than the diffusing concept of an n-rung orthopair fuzzy set, as well as m-rung orthopair fuzzy set. The main advantage of n,m-rung orthopair fuzzy sets is that it can describe more uncertainties than Fermatean fuzzy sets, which can be applie in many decision-making problems. Then, we discover the essential set of operations for the n,m-rung orthopair fuzzy sets along with their several properties. Finally, we introduce a new operator, namely, n,m-rung orthopair fuzzy weighted power average (n,m-ROFWPA) over n,m-rung orthopair fuzzy sets and apply this operator to the MADM problems for evaluation of alternatives with n,m-rung orthopair fuzzy information.

We focus on the complement of (3, 4)-fuzzy sets. We construct some of the fundamental set of operations of the (3, 4)-fuzzy sets.

We apply these operators to select the top-rank university and show how we can choose the bestoption by comparing the aggregate outputs through score values.

The purpose of this paper is to introduce the notion of Fer-matean fuzzy topological space by motivating from the notion of intuition-istic fuzzy topological space, and define Fermatean fuzzy continuity of afunction defined between Fermatean fuzzy topological spaces. For this pur-pose, we define the notions of image and the pre-image of a Fermatean fuzzysubset with respect to a function and we investigate some basic propertiesof these notions. We also construct the coarsest Fermatean fuzzy topologyon a non-empty set X which makes a given function f from X into Y a Fer-matean fuzzy continuous where Y is a Fermatean fuzzy topological space.Finally, we introduce the concept of Fermatean fuzzy points and studysome types of separation axioms in Fermatean fuzzy topological space.

/e purpose of this paper is to define the concept of (3, 2)-fuzzy sets and discuss their relationship with other kinds of fuzzy sets. We describe some of the basic set operations on (3, 2)-fuzzy sets. (3, 2)-Fuzzy sets can deal with more uncertain situations than Pythagorean and intuitionistic fuzzy sets because of their larger range of describing the membership grades. Furthermore, we familiarize the notion of (3, 2)-fuzzy topological space and discuss the master properties of (3, 2)-fuzzy continuous maps. /en, we introduce the concept of (3, 2)-fuzzy points and study some types of separation axioms in (3, 2)-fuzzy topological space. Moreover, we establish the idea of relation in (3, 2)-fuzzy set and present some properties. Ultimately, on the basis of academic performance, the decision-making approach of student placement is presented via the proposed (3, 2)-fuzzy relation to ascertain the suitability of colleges to applicants.

The main objective of this paper is to present the study of α-topological vector spaces. α-topological vector spaces are defined by using α-open sets and α-irresolute mappings. Notions of convex, balanced and bounded set are introduced and studied for α-topological vector spaces. Along with other results, it is proved that every α-open subspace of an α-topological vector space is an α-topological vector space. A homomorphism between α-topological vector spaces is α-irresolute if it is α-irresolute at the identity element. In α-topological vector spaces, the scalar multiple of α-compact set is α-compact and αCl(C) as well as αInt(C) is convex if C is convex. And also, in α-topological vector spaces, αCl(E) is balanced (resp. bounded) if E is balanced (resp. bounded), but αInt(E) is balanced if E is balanced and 0 ∈ αInt(E).

This article examines the beliefs of teachers who teach at scientific departments about teaching mathematics in schools. In exploring their perceptions about the contributing factors that help kurd students to achieve high-scores in math’s subject. Therefore, forty seven teachers (who teach at scientific departs) questionnaire made by the researcher. The data collected was analyzed using descriptive analysis. As a result, it was revealed that the majority of teachers agreed that real life applications, processing skills, using concrete instructional manipulative and conceptual knowledge are very important in teaching mathematics. However, most of the teachers who have participated in this survey was aware of the fact that kurd students have high achievements compared to other students around the world. On the other hand, the results have also shown that kurd students usually concentrate on private tuition to improve their math’s skills, as well as, the parent’s involvement in stimulating them for better results has an active role in their high achievements.
