用粗糙集中的等价关系来刻化等价粒,结合粒计算的处理方法给出了决策表的粒表示、粒运算规则.提出了一种基于决策类逐渐细化条件粒直接获取最简规则的方法.该方法不仅考虑了属性相对独立性,而且能更加充分地挖掘决策表中的知识,并用实例验证了其可行性.

The equivalent relation in rough set theory is used to express equivalent granule.A decomposing model of granular computing in decision information system is developed and an approach about the briefest rule acquisition is presented with adding gradually condition attributes.The correctness and effectiveness of the new algorithm are shown in an example.
