针对决策过程中,方案属性信息的不确定性且信息是分多个阶段给出的,给出了一个不确定多阶段信息集结算子,不确定动态几何加权平均(UDWGA)算子.该算子可以将决策者在多个阶段给出的区间型信息进行集结.给出了基于此算子的不确定多属性决策方法,最后的实例说明方法的有效性和合理性.
In view of the uncertainty of the attribute information in the decision process and the information given in multiple stages, an uncertain multi-stage information aggregation operator and UDWGA operator are given. Subsets can aggregate the interval-type information given by decision-makers in multiple stages. An uncertain multi-attribute decision-making method based on this operator is given. The final example shows the effectiveness and rationality of the method.
