Group Decision Making Based on Triangular Neutrosophic Cubic Fuzzy Einstein Hybrid Weighted Averaging Operators

In this paper, a new concept of the triangular neutrosophic cubic fuzzy numbers (TNCFNs), their score and accuracy functions are introduced. Based on TNCFNs, some new Einstein aggregation operators, such as the triangular neutrosophic cubic fuzzy Einstein weighted averaging (TNCFEWA), triangular neutrosophic cubic fuzzy Einstein ordered weighted averaging (TNCFEOWA) and triangular neutrosophic cubic fuzzy Einstein hybrid weighted averaging (TNCFEHWA) operators are developed. Furthermore, their application to multiple-attribute decision-making with triangular neutrosophic cubic fuzzy (TNCF) information is discussed. Finally, a practical example is given to verify the developed approach and to demonstrate its practicality and effectiveness.


Introduction
Atanassov [1] introduced the IFS, which is a generalization of FS.Atanassov [2] introduced operations and relations over IFSs taking as a point of departure respective definitions of relations and operations over fuzzy sets.Bustince et al. [3] introduced the characterization of certain structures of intuitionistic relations according to the structures of two concrete fuzzy relations.Deschrijver et al. [4] established the relationships between intuitionistic fuzzy sets (Atanassov, VII ITKR's Session, Sofia, June 1983 (Deposed in Central Sci.-Techn.Library of Bulg.Acad. of Sci., 1697/84) (in Bulgarian)), L-fuzzy sets.Deschrijver et al. [5] defined the mathematical relationship between intuitionistic fuzzy sets and other models of imprecision.Jun et al. [6] introduced the cubic set.Mohiuddin et al. [7] showed that the union of two internal cubic soft sets might not be internal.Turksen [8] showed that the proposed representation (1) exists for certain families of the conjugate pairs of t-norms and t-norms, and (2) resolves some of the difficulties associated with particular interpretations of conjunction, disjunction, and implication in fuzzy set theories.
Xu [9] developed some aggregation operators, such as the intuitionistic fuzzy weighted averaging operator, intuitionistic fuzzy ordered weighted averaging operator, and intuitionistic fuzzy hybrid aggregation operator, to aggregate intuitionistic fuzzy values.Xu et al. [10] developed some new geometric aggregation operators, such as the intuitionistic fuzzy weighted geometric (IFWG) operator and the intuitionistic fuzzy ordered weighted geometric (IFOWG) operator.Xu et al. [11] provided a survey of the aggregation techniques of intuitionistic fuzzy information and their applications in various fields, such as decision making, cluster analysis, medical diagnosis, forecasting, and manufacturing grid.Liu et al. [12] introduced and discussed the concept of intuitionistic fuzzy point operators.Zeng et al. [13] defined the situation with intuitionistic fuzzy information and developed an intuitionistic fuzzy ordered weighted distance (IFOWD) operator.The fuzzy set was introduced by Zadeh [14].Zadeh [15] introduced the interval-valued fuzzy set Li et al. [16] proposed group decision-making methods of the interval-valued intuitionistic uncertain linguistic variable based on Archimedean t-norm and Choquet integral.Zhao et al. [17] developed some hesitant triangular fuzzy aggregation operators based on the Einstein operation: the hesitant triangular fuzzy Einstein weighted averaging (HTFEWA) operator.Xu et al. [18] introduced two new aggregation operators: dynamic intuitionistic fuzzy weighted averaging (DIFWA) operator and uncertain dynamic intuitionistic fuzzy weighted averaging (UDIFWA) operator.
The Neutrosophic Set (NS) was projected by Smarandache [19,20].Neutrosophic sets are characterized by fact participation, an indeterminacy-enrollment work and misrepresentation participation, which are inside the ordinary or nonstandard unit interim ] − 0, 1 + [ in order to apply NS to genuine applications.In order to apply NS to real-world applications, Aliya et al. [21] introduced the concept of the triangular cubic fuzzy number.Aliya et al. [22] introduced the triangular cubic hesitant fuzzy Einstein weighted averaging (TCHFEWA) operator, triangular cubic hesitant fuzzy Einstein ordered weighted averaging (TCHFEOWA) operator and triangular cubic hesitant fuzzy Einstein hybrid weighted averaging (TCHFEHWA) operator.
Beg et al. [23] introduced a computational means to manage situations in which experts assess alternatives in possible membership and non-membership values.Przemyslaw et al. [24] introduced a simple test that sometimes might be helpful in detecting non-separability at a glance.
The differences between Reference 21, 22 and the current paper are as Table 1: Table 1.Difference between references 21, 22 and current paper.

Definition 1. [15].Let H be a fixed set, a FS F in H is defined as:F = {(h, Γ F (h)|h ∈ H} where Γ F (h) is a mapping from h to the closed interval [0, 1] and for each h ∈ H, Γ F (h) is called the degree of membership of h in H. Definition 2. Let H is a fixed set and an interval-valued fuzzy set I in H is defined as I = h, R − I (h), and The numbers R Ð (h) and Ω Ð (h) represent, respectively, the membership degree and non-membership degree of the element h to the set Ð.
