摘　　要：在基于可信度的区间数排序方法的基础上,利用粒度意义下属性重要性等概念,给出了一种基于粗糙集理论的属性权重确定方法,将主观权重和客观权重结合起来,建立了一种基于粗糙集理论的教学质量区间数评判模型,使权重确定更加合理,评判结果更加科学、客观.According to the concept of attribution importance of granularity,based on credibility of ranking of fuzzy interval number,this paper puts forward the method of ascertaining attribute weight based on rough sets theory.Combining the subjective weight and objective weight,the teaching quality comprehensive evaluation model based on rough sets theory is established.It can make weight more reasonable and the evaluation results more scientific and objective.

关 键 词：区间数 粗糙集 权重 教学质量 综合评判
