| 摘 要： | 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.

| Abstract: | Aiming at the uncertain and multi-period attribute value in alternative evaluation, an uncertain dynamic weighted geometric averaging operator(UDWGA) is presented. The UDWGA operator can aggregate interval number information provided by decision maker at different periods.A new ranking alternatives method on the basis of DWGA operator is given.Finally,an example is given to demonstrate the effectiveness and efficiency of the method. |
