基于优势决策规则的信息系统综合评估

摘要

分析信息系统安全模型,提出一种基于变一致优势关系粗糙集(VC-DRSA)决策规则的信息系统综合评估方法.对VC-DRSA决策规则的数据进行归纳分析,结合谨慎性原则与净现值最大原则,实现定性评估和定量评估.仿真实例的结果表明,该方法可以对数据进行科学的分类,提高信息系统的数据挖掘效率.%This paper proposes a synthetic assessment method based on the decision rules from Variable Consistency Dominance-based Rough Set Approach(VC-DRSA).By applying the principle of prudence and the principle of maximum net present value, it combines quantitative analysis with qualitative analysis effectively.Besides, this method is a two-stage procedure, first training and then decision, which is under no restraint of some specific assessment models and especially suitable for large scale decision making problems.Simulation results show that this method can classify the data scientifically and improve the data mining efficiency of the information system.
