基于相容矩阵计算的不完备决策系统规则获取算法

摘要

For incomplete information decision systems, two concepts of condition attribute matrix and decision attribute matrix under tolerance relation are introduced in this thesis, and decision-making rule acquisition algorithm based on matrix computing from incomplete information decision-making system are 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.%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计算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。
