Abstract

In a complex decision system, it is unavoidable to deal with the fuzziness of people's thinking, judgment and uncertainness of the information. This paper considers the uncertainness and fuzziness in the complex decision systems, and discusses the problem about extracting the fuzzy weights of the projects from the fuzzy judgment matrix. A new method is developed for ranking fuzzy priorities from fuzzy judgment matrix, and calculation formulae for fuzzy priorities are derived. Finally, an applied example on supplier selection is given for demonstrating application of the method.
