摘要
利用变异粗集的概念与结构,结合变精度粗集的概念,提出基于目标信息系统的变精度变异粗集的概念与结构,给出了变精度变异粗集包含强度定理及其推论,并对此进行了讨论,指出了变精度变异粗集的研究与应用方向。
The article starts to propose the conception and structure of variation rough sets of the variable precision based on the concept and structure of variation rough sets and variable precision rough sets. It follows to present and discuss the theorem of inclusion degree of variation rough sets of the variable precision. Finally, this article identifies the research on variation rough sets of the variable precision and its application.
