Min-Max Normalization — linear rescaling of each criterion column to [0, 1]
MIN-MAX-NORMALIZATION (Min-Max Normalization — linear rescaling of each criterion column to [0, 1]) is a normalization multi-criteria decision-making (MCDM) method introduced by Hwang, C. L., Yoon, K. in 1981. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
Min-max normalisation maps every criterion to [0,1] with 1 = best performer and 0 = worst performer in the current dataset. The result is dataset-dependent: adding or removing alternatives changes all normalised values. Use before methods that require [0,1] inputs (e.g. EDAS, CODAS, MARCOS).
Strengths & limitations
- 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.
- Results depend on the chosen normalisation, weights, and parameter settings.
