从拓扑的包含关系这一全新的视角进一步认识协调近似表示空间的属性约简理论。在此基础上将协调近似表示空间中的等价关系放宽为一般关系,提出了一般协调近似表示空间的概念,并给出了一般协调近似表示空间关系约简理论,指出了可将其转换成一类覆盖族的约简且是协调覆盖决策系统属性约简的一般形式,最后用一个模型给出本文约简理论的应用实例。 From the brand new perspective of topological inclusion relations, we can further understand the attribute reduction theory of coordinating approximate representation space. On the basis of this, we relax the equivalence relations in the space of coordination approximations to general relations and put forward the concept of general coordination approximation spaces, and give a general coordination approximation of spatial relations reduction theory, and point out that it can be converted into a The reduction of generic coverage families is the general form of attribute reduction of coordination and coverage decision-making system. Finally, a model is provided to illustrate the application of this reduction theory.
