Fuzzy ELECTRE II — Fuzzy extension of ELECTRE-II
FUZZY-ELECTRE-II (Fuzzy ELECTRE II — Fuzzy extension of ELECTRE-II) is a outranking multi-criteria decision-making (MCDM) method introduced by Roy, B. & Bertier, P. (canonical crisp); Govindan, K., Grigore, M.C. & Kannan, D. (TFN applicator) in 1973 crisp; 2010 TFN 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-electre-ii extends ELECTRE-II 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.
