A New Method of Multiple Attributes Evaluation and Selection in Fuzzy Environment

In a complex evaluation system, not only it is often necessary to deal with multiple attributes decision problems, but also it is unavoidable to deal with the uncertainness and fuzziness of people’s judgment. This paper considers the multiple attributes and uncertainness decision problems in the complex decision systems, a fuzzy multiple attributes evaluation and selection model is built, a new method is developed for ranking fuzzy priorities from the model, and calculation formulae for fuzzy priorities are derived. Finally, an applied example on suppliers’ selection is given for demonstrating the method.
