fuzzy against operators aggregation comparative
Research gap analysis derived from 2 biology papers in our local library.
The gap
The aggregation operators (IFWA) used to combine expert judgments in the intuitionistic fuzzy Z-number framework were not compared against alternative aggregation methods (such as IFWG or Choquet integral operators); comparative analysis of different aggregation strategies' impact on environmental pollution quality control rankings is absent.; The comparative analysis in Section 4.2 only compares the proposed CFFOWA and CFFOWG operators against operators in IF, PF, and FF settings, but does...

The comparative analysis in Section 4.2 only compares the proposed CFFOWA and CFFOWG operators against operators in IF, PF, and FF settings, but does not explore comparison with other complex fuzzy number frameworks or recently developed aggregation methods.
