针对目前多阶段交互式评价研究数量相对较少并且均是基于点值评价信息的缺陷,以及大多数群体评价研究中忽视了评分区间与可变评价信息的内在联系等不足,综合讨论了一种基于区间数的多阶段交互式群体评价方法。本文首先分析了交互式评价中区间型评价信息的特性,进而提出了评分区间重置算法的设计思想。该算法能够实现评分区间与每轮调整后评价信息的协同调整,并推动交互的进行,使评价信息趋于稳定。然后从稳定性角度出发,设计群体评价信息的稳定性指标,以此讨论交互终止条件。最后给出一个应用算例,算例表明了该方法的可行性和有效性。
In view of the shortcomings of the present multi-stage interactive evaluation research, which are relatively few and all based on the point value evaluation information, as well as the neglect of the internal connection between the evaluation interval and the variable evaluation information in most community evaluation studies, Multi - stage interactive group evaluation method based on interval numbers. This paper first analyzes the characteristics of the interval evaluation information in the interactive evaluation, and then puts forward the design idea of the interval reset algorithm. The algorithm can achieve the coordination adjustment between the evaluation interval and each round of adjusted evaluation information and promote the interaction so that the evaluation information tends to be stable. Then from the stability point of view, we design a group to evaluate the stability of the information index, in order to discuss the interactive termination conditions. Finally, an application case is given. The example shows the feasibility and effectiveness of the method.
