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.
