The number of language D and its fuzzy entropy are defined and a multi-criteria decision-making method based on fuzzy entropy and evidence reasoning is proposed to solve the problem of multi-criteria decision making in language D with incompletely determined criterion weight. The proposed method is based on the language D We can get the optimal weight coefficient by using the linear programming model of fuzzy entropy, and use the evidence reasoning algorithm to determine the comprehensive guideline value of the scheme, then get the optimal scheme.Finally, the validity and feasibility of the proposed method is verified by an example.
