A ranking approach on fuzzy judgment matrix

In the complex control or decision process, it is not evitable to deal with the fuzziness of people's thinking, judgment and uncertainness of the information in the systems. This paper considers the fuzziness in the complex systems, discusses the problem about extracting the fuzzy weights of the projects from the fuzzy judgment matrix, and proposes a ranking approach of fuzzy additive inverse on the column, which is a valid and simple ranking method in the analytic hierarchy process. Finally, an example to apply our approach is presented.
