基于双参数相容关系的区间值信息系统属性约简

摘要

A method of attribute reduction for interval-valued information systems based on dual-parameter consistent relation was introduced. This method can be seen as an extension of the model based on the traditional variable precision tolerance relation. It makes the rough model more flexible and more robust in practical applications. At last,we illustrate this method with an example.%针对区间值信息系统,文章提出了一种基于双参数相容关系的属性约简方法.该方法是对传统变精度相容关系粗糙集模型的一种扩充,可使模型在实际应用中更加灵活,鲁棒性更强,通过实例对该方法进行了说明.
