摘　　要：群决策过程中各成员的评价在决策初始存在分歧,对这些分歧进行一致性分析是群决策过程的一个关键步骤,不剔除与群体意见偏离较远的决策者的评价信息就进行群体意见集结,可能会得出不符合客观实际的结论;讨论了群决策中成员意见的分歧特征,提出了成员评价的集中性和相似性概念;定义了群决策过程中判断个人意见是否与群体意见一致的判断准则,即集中性指标和相似性指标.It is objective reality the membersI viewpoints exist divergences. The consensus analysis to these divergences is a key process in group decision making process. It doesn＇t accord with the reality that we don＇t reject some decision-makers whose viewpoint is far from group＇s. We discuss divergence feature among members; and propose two concepts which are concentration and comparability of group decision making ; and define judgment criterions which are concentration index and comparability index.
