Methods for Multiple Attribute Decision Making Problems with Linguistic Assessment Information

Based on grey correlation theory, this paper proposes a method to solve the multiple attribute decision making problems with linguistic assessment Information. The linguistic assessment information is expressed in the form of triangular fuzzy number. The proposed method is composed of following steps: Firstly, transform the linguistic decision matrix into the single-point one, Secondly, calculate the maximum possible interval for the overall value of the alternatives. Thirdly, calculate the superiority possibility between the alternatives. Fourthly, calculate the ranking values of the alternatives. An example is used to illustrate the proposed approach in the end.
