Dominance-Based Rough Set Approach
DRSA (Dominance-Based Rough Set Approach) is a sorting multi-criteria decision-making (MCDM) method introduced by Greco, S. Matarazzo, B. Słowiński, R. in 2001. 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.

When to use it
DRSA is non-compensatory; suitable for ordinal data without numerical weights.
Strengths & limitations
Strengths
- 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.
Limitations
- Results depend on the chosen normalisation, weights, and parameter settings.
