基于组合权重与vague集的多目标决策方法及应用

A Method for Multiple Objective Decision Making Based on Combinational Weight and Vague Sets

提出了基于组合权重与vague集的多目标决策方法，并将其应用于无人机控制站人机界面评价。该决策方法首先将方案指标值构成的决策矩阵转化为标准化矩阵，然后通过组合权重法计算各指标的权重，并使用专家诊断法确定每个指标的满意度下界和不满意度上界。在此基础上，计算出各方案的vague值并按照评分函数对方案进行最优排序。最后，以实例说明了该方法在无人机控制站人机界面评价中的应用。计算结果表明，该方法较好地解决了指标权重分配，最大限度地避免了决策者在确定满意度的下界和不满意度的上界时的主观任意性，使决策结果合理，是一种有效的人机界面评价方法。

In order to study the man-machine evaluation of the ground control station for unmanned aerial vehicle, a new approach to multiple objectives decision making based on combinational weight and vague sets is proposed in this paper. First, the decision matrix of the evaluation projects is transformed into an objective matrix. Then, the weight of every objective is computed by means of combinational weight meth- od and the acceptable lower boundary of degree of satisfaction and acceptable upper one of degree of dis- satisfaction of every objective are decided by experts＇ diagnosis method. Based on the methods, the vague evaluation of each project is obtained. Finally, the method is used for man-machine interface evaluation in unmanned aerial vehicle. The result shows that the method resolves the weight＇ s allocation and avoids the decision-maker＇ s subjective tendency about deciding the degrees. It is a good multiple objectives decision making method for man-machine interface evaluation.
