Information Systems Risk Evaluation Based on the AHP-Fuzzy Algorithm

The AHP-Fuzzy assessment method is a combination which unifies the AHP method and the fuzzy mathematics. AHP can synthesize human's subjective qualitative judgment, form the weighting of each policy- making factor, and avoid appearing the logic reasoning fault in the complex decision-making question. The fuzzy mathematics, simulating the characteristic of human in making the judgment, is good at processing the uppercase, the ambiguous information. Therefore, AHP-Fuzzy, unifying AHP and the fuzzy assessment method, can unify both merits, and make decision-making more scientific. Through the introduction of AHP, the combination of fuzzy comprehensive evaluation from a combination of qualitative and quantitative point of view for the establishment of an integrated information system risk assessment model.
