An outranking approach for multi-criteria decision-making problems with simplified neutrosophic sets

- The novel operations of simplified neutrophic numbers (SNNs) and relational properties are developed.
- Some outranking relations for SNNs are defined based on ELECTRE, and properties among the outranking relations are further discussed in detail.
- Based on the outranking relations of SNNs, the ranking approach is developed to handle MCDM problems.
