Spherical Fuzzy Z-Number CRITIC Weighting
SFZN-CRITIC (Spherical Fuzzy Z-Number CRITIC Weighting) is a weighting multi-criteria decision-making (MCDM) method introduced by Niu, J. in 2024. 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
Output is an objective weight vector summing to 1 — criteria with high variability AND low correlation with other criteria receive the largest weights. Use these weights downstream in any SFZN-compatible ranking method (SFZN-CRADIS, SFZN-MARCOS, SFZN-TOPSIS). The score function ℑ collapses the SFZN's six components into a single scalar; criteria with discriminating scores AND independent information content dominate.
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.
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
