通过介绍模糊决策精度的概念,引入变精度不协调SFD信息系统;利用拓扑学中的连通性,在变精度不协调SFD信息系统中提出连通下(上)近似变精度协调集和连通下(上)近似变精度约简的概念;给出通过辨识函数计算连通下(上)近似变精度约简的方法,并给出了一个算例.
By introducing the concept of fuzzy decision precision, the variable precision uncoordinated SFD information system is introduced. By using the connectivity in topology, the variable precision uncoordinated SFD information system is proposed to connect () ) Approximation to reduce the accuracy of the concept of reduction; through the identification function to calculate the connection under the (approximation) method to reduce the accuracy of approximation, and gives an example.
