HF-QUALIFLEX: Hesitant Fuzzy extension of QUALIFLEX
Zhang, Z. X., Xu, Z. S. · 2015
Method assistant
Grounded explanations: it explains the method, it does not compute.
Assumptions to verify
- •Number of alternatives m ≤ 6 for tractable permutation enumeration
- •HFE membership values strictly in [0,1]
- •Reference HFE h_ref defined (typically h={1} for benefit criteria)
When not to use
- •m > 6 alternatives: use HF-TOPSIS or HF-ELECTRE instead
- •Cardinal comparisons preferred: concordance only captures ordinal information
Commonly paired with
- •AHP + HF-QUALIFLEX (common)
- •ENTROPY + HF-QUALIFLEX (uncommon)
