Local feedback mechanism based on consistency-derived for consensus building in group decision making with hesitant fuzzy linguistic preference relations

Considering that hesitant fuzzy linguistic preference relation (HFLPR) is an effective way to express decision makers’ (DMs’) hesitant qualitative preference information for a pair of alternatives or attributes, this paper pays attention to priority weights and consensus of HFLPRs in group decision making (GDM). First, a new similarity measure is presented to measure the similarity of hesitant fuzzy linguistic term sets (HFLTSs), then a...
