A weighted value method for multicriteria decision-making

Complex decision-making problems are often characterized by multicriteria phenomena and fuzziness inherent in the structure of information and therefore require suitable scientific solution methods. Especially, when similar dependent criteria are introduced, the problems become more complex. This paper presents a fuzzy intersectional dependence relation model for this kind of multicriteria decision-making problems. The model proposed by the authors is based on the fuzzy relation from fuzzy systems theory. In the case of introducing similar dependent criteria, the rank reversal by distortion of weights is hard to occur by the present proposed method. A numerical example is presented to illustrate the use of the model. [In Korean.]
