摘　　要：基于论域划分的粒度模型,提出了粒度间的偏序关系和拟序关系以及粒度的"和"运算与"乘积"运算;运用粒度与二进制数串一一对应的基本思想,实现了上述序关系和运算的"可计算性",以此为工具讨论了决策规则的提取问题。Based on the model of division in universe, the partial order relation and preorder relation among granules are discussed and the operation on sum and product of granules are studied. According to the basic thing about the binary expression of granules, the arithmetic on the order relation and operation which can be applied to the discovery of decision roles is obtained.

关 键 词：粒度 二进制数串 可计算模型 决策规则
