摘    要:合理确定专家权重是群组赋权的关键。本文在分析同类研究的基础上,提出了基于理想排序的群组G2方法来确定专家权重。论文的主要特色是根据循环修正的思路利用平均值法、Board法和Copealand法对通过一致性检验的专家排序进行重排序,从而确定评价指标的理想排序,然后通过比较各通过一致性检验的专家排序和理想排序的相关性的大小来确定专家权重,保证了专家权重合理的反映了专家差异,保证了指标最终权重反映出群体决策思想。

关 键 词:群组G2法  理想排序  专家权重

Abstract:The key point of group empowering is to reasonably decide the expert weight.Based on analyzing the similar research works,this paper proposes the G2 method based on optimal-order to decide the expert weight.The contribution and special lies in determining the optimal-order by the thought of Circulating Revision and rearranging expert order by ways of mean,Board and Copealand. And then decides the expert weight by the relativity between expert order and optimal-order,which reflects expert discrepancy,guaranteeing final indexes weight could reflect group decision.
Keywords:group-G2  optimal-order  expert weight
