摘　　要：在属性具有偏好关系的不完备目标信息系统中,在对已有模型的两种优势关系分析研究的基础上,提出一种上α优势关系。引入抗噪因子β,建立序不完备目标系统中基于上α优势关系的粗糙集模型,同时对构造的上α模型进行相关的性质分析和证明,结果显示了模型的可用性与实用性。On the basis of analysing and studying two dominance relations in existing model,we present in incomplete objective information system whose attributes have preference relation an above-α dominance relation,and introduce the concept of anti-noise factor β to build in sequence incomplete objective system a rough set model which is based on above-α dominance relation. At the same time,we also discuss and prove the corresponding properties of this new model,and testify its usability and practicability.
