| 摘 要： | 获取决策表规则时，通常需要进行属性约简和属性值约简。该文分析属性值约简，针对协调决策表提出一种通过构造决策矩阵直接获取最简规则的方法。将原来考虑条件属性集和决策属性集决定的等价类之间的关系，转变为仅考虑决策矩阵同行元素之间的代数关系。通过实例验证了该方法的可行性。

| Abstract: | Acquisition of decision table rule usually needs two steps which are attribute reduction and attribute value reduction. This paper analyses attribute value reduction, and presents a method to acquire briefest rules directly by constructing decision matrix in consistent decision table. This method transforms original considering equivalent relation between condition attribute and decision attribute into considering algebra relation of elements in sameness line in decision matrix. The effectiveness of the algorithm is validated in an example. |

| Keywords: | rough set attribute value reduction briefest rule decision matrix |
