摘要：

由粗糙集变动特性,定义不同时刻两个粗糙集变动度。根据不同时刻不同变化的转换概率,研究粗糙集状态的转移规律及两种稳定状态,并讨论粗糙集与属性集变动特征,给出算例分析。

关键词: 变动特性;变动度;转移概率;稳定状态

Abstract:

Based on dynamic characteristics of Rough sets, the concepts of two dynamic degrees about Rough sets at different time are proposed. By using transition probability at different time,transition law and two steady-states are researched. Dynamic characteristics of Rough sets and attribute sets are discussed. Finally, an example analysis is given by using these results.

Key words: dynamic characteristics; dynamic degree; transition probability; steady-state
