An interval-valued intuitionistic fuzzy MABAC approach for material selection with incomplete weight information
A hybrid group decision making approach is proposed for material selection. Uncertain and vague information is handled by interval-valued intuitionistic fuzzy sets. A maximizing optimization model is established for determining criteria weights. An extended group decision making method is used to rank alternative materials. The applicability and effectiveness are illustrated with two application examples.
