imprecise, incomplete and inconsistent information that exists in the real world. Simplified neutrosophic sets (SNSs) have
been proposed for the main purpose of addressing issues with a set of specific numbers. However, there are certain problems
regarding the existing operations of SNSs, as well as their aggregation operators and the comparison methods. Therefore, this
paper defines the novel operations of simplified neutrosophic numbers (SNNs) and develops a comparison method based on
the related research of intuitionistic fuzzy numbers. On the basis of these operations and the comparison method, some SNN
aggregation operators are proposed. Additionally, an approach for multi-criteria group decision-making (MCGDM) problems
is explored by applying these aggregation operators. Finally, an example to illustrate the applicability of the proposed method
is provided and a comparison with some other methods is made.
