New Method of Determining objective criterion weights
NMD (New Method of Determining objective criterion weights) is a weight objective multi-criteria decision-making (MCDM) method introduced by Bulut, E. in 2017. 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
NMD assigns higher weight to criteria whose alternatives perform further below the maximum (lower μ_j → more spread from the ideal). It is fully objective and simple to compute. Criteria where all alternatives score near 1 (all close to best) get low weight.
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.
