(8)AHPの感度分析結果を用いた代替案ウェイトの表現法
第21回ファジィシステムシンポジウム講演論文集, pp.27-28, 2005-9
AHP is one of major methods for a domain of decision making. However indeed,
a comparison matrix does not always have good consistency to enough rely
upon the data. In these cases, we suppose that answers from a decision-maker
have ambiguous or fuzziness and then weights also have that kind of property.
Therefore, it is natural to represent the weights by use of fuzzy sets. We
define a kind of representation of weights by using results from the sensitivity
analysis. And also propose an approach to composition the weights. At last
the study shows how weights of alternatives include fuzziness when a comparison
matrix has relatively not so good consistency.
