Fuzzy PROMETHEE — Fuzzy extension of PROMETHEE
FUZZY-PROMETHEE (Fuzzy PROMETHEE — Fuzzy extension of PROMETHEE) is a outranking multi-criteria decision-making (MCDM) method introduced by Goumas, M., Lygerou, V. in 1986 crisp; 2000 variant applicator. 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
fuzzy-promethee extends PROMETHEE to handle Fuzzy uncertainty. All arithmetic operations (normalisation, weighting, distance computation) are performed using Triangular Fuzzy Number (TFN: l, m, u) algebra. The final scores are defuzzified via centroid (l+m+u)/3 before ranking.
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.
- May exhibit rank reversal when alternatives are added to or removed from the set.
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
