摘要
利用属性重要性等概念,提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综合评判模型,使权重确定更加合理,评判结果更加科学、客观,最后通过实例验证了该方法的实用性和可行性.
According to the concept of importance of attribute, this paper puts forward the method of ascertaining attribute weight based on rough sets teory. Combining the subjective weight and objective weight, the teathing quality comprehensive evaluation model based on rough sets theory is established. It can make weight more reasonable and the evaluation results are more scientific and objective,finally the usability and feasibility for this method is verified through living examples.
