摘　　要：介绍了多种确定权重的方法,给出了各种分类方法的优缺点,利用粗糙集的不可分辨关系、上下近似、属性约简、属性依赖性等性质,探讨了一种新的赋权法——粗糙集赋权法,该模型剔除了冗余的指标,更加客观地评价了指标的重要程度,为系统综合评价中确定指标权重提供了一条新途径。This article introduces several weight determination methods and gives their advantages and disadvantages;one kind of new weight determination method,rough set weight method,is discussed by analyzing the characteristics of rough set,such as undistinguished relationship,the upper and lower approximation,attribute reduction,dependent nature of rough set and principles of least-squares and this model removes redundant indicators and more objectively evaluates the importance of the indicators,which provides a new way to determnine the weight in the system comprehensive assessment.

关 键 词：系统综合评价 权重 粗糙集 属性约简
