摘要: 针对现有基于粗糙集理论属性客观权重确定方法的不足,将基于代数观和信息观的权重进行有机集成,建立了两者结合的属性权重最优化数学模型,从而得到综合权重的最优解。最后通过实例说明了该方法的有效性。

Abstract: In view of the deficiency in existing methods for Objective Attribute Weight Determining(OAWD) based on rough set theory,by integrating information view and the algebra view of rough set,optimization method of OAWD is given,then the optimal solution of integrated weight is got.Finally,an example is given to explain the availability of this method.

Key words: rough set, significance of the attribute, weight, algebra view, information view
