Considering that the present study on multi-stage dynamic interactive group evaluation is few and most of the evaluation information is accurate numbers or interval numbers ,in addition ,the majority of interactive group evaluation lack judgment of evaluation information quality ,this paper proposes a method of multi-stage dynamic interactive group evaluation based on multi-granularity uncertain linguistic information .Firstly ,the paper gives a new multi-granularity linguistic transformation function ,which can convert multi-granularity uncertain linguistic information to single-granularity uncertain linguistic information ;Then ,a new linguistic type stability index is designed ,which is used to explore the condition of interactive termination ;Finally ,the paper defines two uncertain pure linguistic operators to aggregate the vertical and horizontal information .A practical example illustrates the validity and rationality of the proposed methods .%针对目前多阶段交互式群体评价研究较少且评价信息多为精确数或区间数的问题,以及大多数交互式群体评价缺乏对评价信息质量判断的不足,提出了一种新的多粒度不确定语言信息下的多阶段交互式群体评价方法.首先,定义了一个多粒度语言转换函数,将多粒度不确定语言信息一致转换为同一粒度下的不确定语言信息;其次,给出了一个语言型稳定性指标,以探讨交互终止的条件;最后,基于2个诱导不确定纯语言算子,分别对评价信息进行"横向"和"纵向"集结.实例分析验证了该方法的有效性与合理性.
