Group decision making by a last aggregation approach under interval-valued Pythagorean fuzzy environment for sustainable project decision

Interval-valued Pythagorean fuzzy sets (IVPFSs) as enhanced type of (PFSs) improve the expression degrees membership, non-membership and hesitancy in comparison with intuitionistic (IFSs). In this paper, to use advantages IVPFSs a new group decision-making method is introduced based on linear assignment (LAM). approach, subjective objective weights criteria are taken into account. Moreover, applies ranking for IVPFSs. To avoid shortcomings first aggregation methods, approach involves last approach. Finally, used case study sustainable project evaluation order depict applicability method.
