Interval Type-2 Fuzzy Envelope of Proportional Hesitant Fuzzy Linguistic Term Set: Application to Large-Scale Group Decision Making

Large-scale group decision-making (LS-GDM) problems are common in the daily life of human beings. Both information fusion and computing with words (CWW) technologies LS-GDM suffer from challenges. In current research, a proportional hesitant fuzzy linguistic term set (PHFLTS) will be applied to capture preferences sub-groups LS-GDM, which decreases lost processes. Novel semantic representation models PHFLTS, such as type-1 envelope interval type-2 envelope, respectively studied. The application proposed entropies facilitates CWW process PHFLTS under framework approach. particular, uncertainties contained can reflected comprehensive way when is applied, contributes decrease during process. A novel method cooperating proposed, weights for determined by size, cohesion, degree reliability among sub-groups. Finally, decision well tools urban renewal plan selection.
