Analytic Hierarchy Process (AHP) was proposed by Saaty, T.L. in 1977, and has been widely used in decision making. When we actually use AHP, it often occurs that a comparison matrix has a little bad consistency, since there are many activities. In these cases, we consider that decision makers answers have ambiguous or fuzziness and that the weights also contain them. Therefore, the necessity to represent the weights using fuzzy sets arises, to see how fuzzy the weights are, the result of sensitivity analysis is useful. In this paper, we propose a fuzzy weight in AHP. It shows how the result of the AHP has fuzziness, when consistency of comparison matrix is a little bad.
