Heterogeneous multi-attribute group decision making method based on shapely value correction

A group decision making method based on the combination of Shapely value and compromise optimization (VIKOR) is proposed for group decision making with unknown weights and heterogeneous information. Firstly, considering the diversity of evaluation index types, the heterogeneous information is transformed into interval constitution fuzzy information. Secondly, the related theory of Shapely values is used to propose a kind of theory. Then the basic framework of VIKOR is used to calculate the ranking of each scheme.
