摘要: 在群决策理论中,如何获取合理的决策规则是一个重要的研究内容。针对条件属性具有优势关系及决策值为模糊数的多决策信息系统,构建了基于优势关系的模糊目标信息系统变精度粗糙集模型,给出了该模型的几种知识约简定义;通过构造适当的启发式函数,得到了该模型的优势下分布约简算法。最后将该模型应用于计算机审计风险评估,得到了较为合理的评估规则。

Abstract: In group decision-making theory, how to acctuire reasonable decision rules is an important issue. This paper constructed a dominance relation-based variable precision rough set model (VPRSM) in fuzzy objective information systerns, and proposed some knowledge reduction definitions such as dominanc-based lower/upper distribution reduction.Using a heuristic function, we devised a lower distribution reduction algorithm. Finally, this model was applied to computer audit risk appraisal and some reasonable appraisal rules were acquired.

Key words: VPRSM, Dominance relation, Uroup decision-making, Computer audit risk
