MCDMDecision-makingAggregationOperatorMath steps
Reference Alternative based Aggregation Technique
RAT (Reference Alternative based Aggregation Technique) is a aggregationoperator multi-criteria decision-making (MCDM) method introduced by Orakçı, E. in 2024. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.
Key highlights
- Follows a transparent, reproducible computational procedure that can be audited step by step.
- Handles multiple criteria of differing scales and units within a single decision matrix.
