区间型多属性群体专家权重的确定方法

针对方案偏好和属性值均为区间数的多属性群决策问题，研究了群体专家权重的确定，并提出了一种新的群决策方法．通过定义区间数向量的内积，计算专家评判的相似度和差异度，进而客观地确定了专家的权重．求解最小化主、客观偏差的目标规划模型，得到了属性的权重，利用方案的群体综合属性值给出排序结果．供应商选择的应用实例验证了方法的可行性和合理性．

Method of Determining Experts' Weights for Interval Multi-attribute Group Decision-making

For the problem of interval multi-attribute group decision-making,in which the attribute values and the preference information are in the form of interval numbers,this paper studies the determination of experts' weights and proposes a new group decision-making method.After defined the inner product for interval vectors, computed the degrees of similarity and discrepancy for experts' judgment,the experts' weights are determined objectively.By solving the objective programming of minimizing the deviation betw...
