ファジィ理論による相対的重要度の推定と道路周辺環境の総合評価への応用

抄録

The objectives of this study are to propose the estimation method of relative weights usingfuzzy set theory and to certify the usefulness of this method for environmental assessment. The estimation method using fuzzy set theory is mainly based by the pair comparison method, fuzzy relation, and Graph-Matrix method. The proposal method has some merits such as the reduction of burden for answering questionaire, the increace of freedom for selecting pair comparisons, the acquisition of relative weights without-fail, and so on. To show the usefullness of proposal method, this is applied to the total assessment on road environment by earring out the survey through the questionaire with the neighborhood along the road. So we get the results as the good estimations of relative weights, total environmental assessment and the usefullness of proposal method.
