| 摘 要： | 对多属性决策问题和信息集结问题进行了研究,分析了已有Vague集方法,并通过例子说明其不足之处.提出了一种多属性决策的Vague集方法.定义了方案对目标的支持(反对、中立)度等概念,利用目标优属度矩阵对属性值及属性权重进行集结,从而得到方案的Vague估计值.定义正(负)理想Vague值,并用TOPSIS法对方案进行排序和选优.算例验证了该方法的有效性和可行性.

| Abstract: | The multi-attribute decision making and information aggregation problems are studied. The present vague set method is anal-yzed and their shortcoming is showed by example. A new vague set method for multi-attribute decision making is presented. The concepts of the favor (against,neutral) grade of each alternative to the attributes are defined. Using the objective-grade-membership matrix,the attribute values are aggregated,and the vague evaluation of each alternative is obtained. The idea (anti-idea) vague values are defined,then all alternatives are ranked and the best one is selected using the TOPSIS method. An example shows that the proposed method is effective and feasible. |
