从属性集角度研究不协调决策信息系统的分配约简问题。定义了一种决策分配二元关系,并利用这种关系建立了属性集幂集上的等价关系,由此产生依赖空间。同时利用决策分配二元关系和依赖空间给出了不协调决策信息系统分配协调集的判定定理,进而得到了一种保持不协调决策信息系统分配不变的属性约简方法。同时通过实例验证方法的有效性。
Research on the Problem of Discrepancy and Discretization in the Uncoordinated Decision Information System from the Perspective of Attribute Set. The definition of a decision-making binary distribution, and use this relationship to establish the equivalence of attributes on the power set, resulting in dependent space. At the same time, the judgment theorem of distributive coordination set of disharmony decision-making information system is given by using the binary relation and the relying space of distributive decision-making, and then a property-reduction method of keeping unallocated distributive decision-making information system is obtained. At the same time, the validity of the method is verified through examples.
