Fuzzy Delphi — Expert consensus with triangular fuzzy opinions and defuzzification
FUZZY-DELPHI (Fuzzy Delphi — Expert consensus with triangular fuzzy opinions and defuzzification) is a weight subjective multi-criteria decision-making (MCDM) method introduced by Kaufmann, A., Gupta, M. M. in 1988. 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.

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
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
