On a Representation for Weights of Alternatives by Use of Sensitivity Analysis in AHP

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.
