Study on Risk Evaluation of Enterprise Information Systems

Abstract In order to evaluate enterprise information systems’ risk quantitatively, a new method for risk evaluation is studied. Firstly, a set of evaluation system is proposed for enterprise information systems. Secondly, the evaluation model is built and the corresponding algorithm, i.e., Refining High indexes (RHI) algorithm, is given. Finally, the application of the evaluation system, the evaluation model and RHI algorithm is explained through an example, which provides quantitative references for enterprise information systems’ risk evaluation.
