Fuzzy VIKOR — Fuzzy extension of VIKOR
FUZZY-VIKOR (Fuzzy VIKOR — Fuzzy extension of VIKOR) is a ranking multi-criteria decision-making (MCDM) method introduced by Opricovic, S. in 2011. It turns a decision matrix of alternatives scored on multiple criteria into a structured, reproducible result.

When to use it
fuzzy-vikor extends VIKOR 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.
