Z-Number Fuzzy Compromise Ranking from Distance to Ideal Solution
ZF-CRADIS (Z-Number Fuzzy Compromise Ranking from Distance to Ideal Solution) is a ranking multi-criteria decision-making (MCDM) method introduced by Puška, A. Božanić, D. Nedeljković, M. Janošević, M. in 2022. 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 a compromise score Q_i per alternative — higher means the alternative is simultaneously closer to the ideal solution and farther from the anti-ideal. The top-ranked alternative is the best green supplier under the expert consensus. Pair this method with ZF-LMAW or any other Z-aware weighting source; the input decision matrix supports per-cell Z-number reliability. When experts are uncertain (low B-rating), the implicit √α down-scaling correctly reduces that cell's influence on the final 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.
- Assumes full compensation — a strong score on one criterion can offset a weak score on another.
