FIA — Fuzzy Information Axiom (Axiomatic Design under fuzzy data)
FUZZY-INFORMATION-AXIOM (FIA — Fuzzy Information Axiom (Axiomatic Design under fuzzy data)) is a ranking multi-criteria decision-making (MCDM) method introduced by Kahraman, C., Kulak, O. in 2008. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
FIA evaluates how well each alternative's achievable range (system range) matches the design target range under fuzzy uncertainty. Lower total information content I_i (in bits) means the alternative satisfies the functional requirements more reliably. An infinite I_ij means the alternative cannot satisfy FR j at all (zero intersection between system range and design range).
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.
