摘要
针对不完备信息决策系统问题,引入相容关系下条件属性矩阵和决策属性矩阵的相关概念,并由此提出一种基于矩阵的不完备信息决策系统规则获取算法。该算法无需计算核属性,通过矩阵计算,能够直接从不完备信息决策系统中提取所有的决策规则集。理论分析和实例结果均表明该算法的有效性和实用性。
For incomplete information decision-making systems, two concepts of condition attribute matrix and decision attribute matrix under tolerance relation are introduced, and decision-making rule acquisition algorithm based on matrix from incomplete information decision-making system is presented. The algorithm can extract all rules through matrix calculating from decision-making system directly without calculating core attributes. Theoretical analysis and example results show that the algorithm is effective and practical.
