 AHP (Analytic Hierarchy Process) has been widely used in a domain of decision making. However, actually, it often occurs that data of AHP loses its reliability, because a comparison matrix there in does not always have enough consistency. For these cases, fuzzy representation for activity's weights using results from the sensitivity analysis is useful. In this paper, with some assumptions, we can also represent alternative's overall weights. Since an idea of less ambiguity is employed, it can show how results of AHP have fuzziness when the comparison matrix does not have enough consistency.
