The vectors of alternative, ideal and critical alternative are defined. A projection measure method is proposed, in which the attribute values are in the form of interval-valued intuitionistic fuzzy set. A non-linear programming model, based on the Jaynes’ maximum entropy principle and alternatives’ fair competition, is established to obtain the attribute weights. A new relative closeness degree formula based on ideal and critical alternative is presented in order to rank the alternatives. Finally, a numerical example is given to verify the effectiveness and feasibility of the proposed method. %U http://cea.ceaj.org/EN/10.3778/j.issn.1002-8331.1503-0171
