Said Broumi This paper introduces the concept of cubic spherical neutrosophic sets (CSNSs), a geometric representation of neutrosophic sets, as well as a specification of its operational principles. In CSNs, two aggregation operators are investigated. The shape of CSNSs represents the evaluation values of alternatives with respect to criteria in a MCDM strategy based on the two aggregation operators and cosine distance for CSNSs. The cosine distance between an alternative and the ideal alternative is used to rank them, and the best alternative(s) can be selected. A numerical example concludes by demonstrating the use of the suggested method. 2023 2023 172 180 10.54216/IJNS.210418 https://www.americaspg.com/articleinfo/21/show/1990
