In this paper, in order to apply the concept of IVI-octahedron sets to MCDGM problems, we define some aggregation operators via IVI-octahedron sets and obtain some their properties. We define some aggregation operators via IVI-octahedron sets and obtain some their properties. We present a MCGDM method with linguistic variables in IVI-octahedron set environment. Finally, we give a numerical examples for MCGDM problems.Keywords: IVI-Octahedron set, Score function, accuracy function, IVI-octahedron Bonferroni mean operator, IVI-octahedron averaging operator, IVI-octahedron geometric operator, generalized IVI-octahedron averaging operator, generalized IVI-octahedron geometric operator

Data envelopment analysis (DEA) is a mathematical technique based on linear programming applied to evaluate the efficiency of decision-making units dealing with multiple inputs and outputs. In classical DEA models, it is assumed that input and output data are accurate though real-world applications require considering inaccurate and ambiguous data. Moreover, linguistic forms may be intuitionistic in nature rather than fuzzy. We propose a novel approach to solve DEA models characterized by intuitionistic fuzzy data. The model is transformed into a linear programming problem with an intuitionistic fuzzy objective function, and an alphabetical technique is applied to solve it. The proposed approach is easy to implement, involving a lower number of calculations than more computationally demanding techniques introduced in the literature. It also provides a set of ranking results that are significantly correlated with those derived from the implementation of more complex techniques. Its applicability would allow to extend the analysis of intricate evaluation scenarios common to the standard DEA literature into intuitionistic fuzzy environments.Keywords: Data envelopment analysis, Intuitionistic Fuzzy Number, Intuitionistic Fuzzy Performance, Accuracy Function
