摘要
Abstract
In recent years, the research on multi-granulation rough set has become one of hot research. Firstly, this paper defines support function and discusses the properties of support function. Secondly, this paper proposes the generalized multi-granulation rough set model by using support function, defines the upper and lower approximation operators̓and discusses the properties of the approximation operators. What’s more, this paper studies the measure and properties of generalized multi-granulation rough set in ordered information system, as well as the relationship of generalized multi-granulation rough set approximation operators and multi-granulation rough set approximation operators in ordered information system. Finally, in order to better explain the practical application value of this model, an example on student admitting in college illustrates the feasibility and efficiency of this model.关键词
