Open publisher page 0 citations

Abstract

Analytic Hierarchy Process(AHP) method was applied to assess the risk of an information system.The criterion hierarchy in the structure of AHP included three factors,probability,influence and uncontrollability.The weight of risk factors based on the criterion hierarchy was decided by group decision.The decision maker's weight is determined by the comparability degree of their own judgment matrix from other matrices,and then a consensus matrix was obtained from aggregating these decision maker's matrices by the method of weighted geometric mean.
