Interval Neutrosophic Sets and Their Application in Multicriteria Decision Making Problems

الملخص EN

As a generalization of fuzzy sets and intuitionistic fuzzy sets, neutrosophic sets have been developed to represent uncertain, imprecise, incomplete, and inconsistent information existing in the real world.

And interval neutrosophic sets (INSs) have been proposed exactly to address issues with a set of numbers in the real unit interval, not just a specific number.

However, there are fewer reliable operations for INSs, as well as the INS aggregation operators and decision making method.

For this purpose, the operations for INSs are defined and a comparison approach is put forward based on the related research of interval valued intuitionistic fuzzy sets (IVIFSs) in this paper.

On the basis of the operations and comparison approach, two interval neutrosophic number aggregation operators are developed.

Then, a method for multicriteria decision making problems is explored applying the aggregation operators.

In addition, an example is provided to illustrate the application of the proposed method.
