A method of grey incidence analysis for group decision-making under fuzzy information

The aim of this paper is to extend classical grey incidence decision-making to fuzzy information. First, the grey incidence coefficient formula of triangular fuzzy number is proposed based on idea of grey system theory and expectation formula of triangular fuzzy number. Then, the method of grey incidence analysis for multiple attribute decision-making with linguistic variables is given. The proposed method makes the decision-making more flexible and the result more practical. Finally, an example is shown to illustrate the procedure of the proposed method.
