Risk Evaluation Scheme for Accounting Information System Based on Analytic Hierarchy Process

The risk evaluation of accounting information system is difficult and complicated and it needs the integration of qualitative and quantitative methods to improve the effectiveness of evaluation results. This paper provides a comprehensive risk evaluation approach for the information system security considering the uncertainty of security risk factors. It adopts AHP, group decision and information entropy to perform experts evaluation from risk probability, influence and uncontrollability, and compute the experts weights. By case analysis, the scheme proposed in this article is an effective and operable evaluation method compared to existing methods for the risk evaluation of enterprise accounting information system.
