A fuzzy multiple attribute decision making method based on possibility degree

A fuzzy multiple attribute decision making method is investigated, in which the weights are given by interval numbers and the attribute values are given by the form of triangular fuzzy numbers or linguistic terms. A possibility degree formula for the comparison between two trapezoidal fuzzy numbers is proposed. According to the ordered weighted average (OWA) operator, an approach is presented to aggregate the possibility matrixes based on attributes and then the most desirable alternative is selected. This fuzzy multiple attribute decision making method is used in the field of financial investment evaluation, the set of attributes of the decision making program is built by analyzing of financial and accounting reports in the same industry. Finally a numerical example is provided to demonstrate the practicality and the feasibility of the proposed method.
