摘　　要：针对多目标决策问题中指标权重难以准确度量、传统的赋权方法始终无法达到主客观的有机统一的现状,引入证据理论中的合成规则,通过构建一种耦合模型将传统的主客观组合赋权模型进行有效合成,所得结果不仅满足指标的客观性,同时也体现了决策者的主观偏好,合成结果与传统的线性组合相比,所求指标权重更加突出定量指标的客观性和定性指标的主观性。最后通过实例论证,证明了该耦合模型可以良好地运用在多目标决策问题中。In response to a situation that it is not easy to accurately compute the indicator weight in multiple objec- tive decisions, and it is unable to achieve effective harmonization of subjective and objective when the traditional methods were used to calculate the weights, the combination rule of evidence theory was introduced in this article, which was used to combine the weights in traditional method by using the combination weighting model effectively by setting a coupled model, and the results were not only objective but also fit the subjective preferences of decision makers. The weights computed by the combination rule were more advanced, because the objectivity of the quanti- tative indicators and the subjectivity of qualitative indicators were highlighted when compared with those results of linear combination. At last, the coupled model proveds that it can be effectively used in multiple objective decision issues by an example argument.
