摘　　要：定义了梯Vague数和基于决策者风险态度的Vague信心度,提出了一种基于决策者Vague信心度的信息不完全的模糊多准则决策方法.该方法利用线性规划模型求出准则权重,并对方案在各个准则值下的决策者的Vague信心度进行集成,求出决策者对各个方案的综合信心度,进而利用可能度法对方案进行排序.最后实例验证了所提出方法的合理性与有效性.Trapezoidal Vague numbers and the decision maker＇s Vague confidence degree based on the risk attitude of decision maker are defined.A fuzzy multi-criteria decision making method based on decision maker＇s Vague confidence degree under incomplete information is proposed.In this method,criteria weights are derived through a linear programming model,and the decision maker＇s confidence degrees for alternatives are obtained through integrating all the decision maker＇s confidence degrees of criteria values in every alternative. Alternatives are ranked with the possibility degree method.An example shows that the proposed method is reasonable and effective.
