摘　　要：利用基于优势关系的模糊粗糙集模型,讨论了模糊决策信息系统中优化序决策规则的获取问题。利用优势关系定义了模糊目标信息系统中对象的三种属性约简。给出了它们的判定定理,构造相应的区分函数,利用布尔推理技术计算对象的属性约简,得到三类新的优化序决策规则。In the fuzzy decision information systemt,he acquisition of optimal ordered decision rules is discussed by using the fuzzy rough set model based on dominance relation.Firstlyt,hree kinds of attribute reduction of objects in fuzzy objects information system are defined by using dominance relation.Then the judgment theorems are given,and discernibility func-tions with corresponding to them are constructed and used to compute the attribute reduction of objects by using Boolean reasoning techniques.Finally,based on these reductionst,hree new types of optimal decision rules are obtained.
