心理阈值协同视角下的群体评价方法及应用

Group Evaluation Method and Its Application from the Psychological Threshold Cooperation Perspective

针对传统群体评价方法均不考虑评价者存在的心理阈值这一现象,提出一种心理阈值协同的群体评价方法。首先,将心理阈值协同的群体评价方法进行了前提假设与过程描述;其次,构建极大型、极小型、居中型、区间型指标相应的群体赋值心理阈值量化算法,根据量化后的心理阈值对评价值矩阵进行调整;再次,给出了群体指标赋权的心理阈值量化及权重值矩阵调整方法;最后,对调整后的评价值矩阵与权重值矩阵进行集结,得出最终评价结果。具体算例表明,该方法有效且可行。

In the face of complex evaluation problems it requires the joint participation of multiple evaluators,which is termed group evaluation.Normally there are some different evaluation results from different evaluators in the group evaluation process.The differences are composed of evaluators' rational analysis and subjective psychological effect.In which rational analysis as experience or knowledge is objective and difficult to change.Thus,reduce group evaluators' subjective psychological effect results is an important part of rational group evaluation process design.Psychological threshold is an essential component of the subjective psychological effect.It is defined as:psychological qualitative critical point that just can cause feelings or perceived differences in the minimum amount of stimulation.Different evaluators' psychological threshold would lead to some deviations between evaluation result and true value.The psychological threshold differences are produced during the process of evaluators score on evaluated objects' index values or assign weighs according to the degree of importance.Therefore,a new method of group evaluation is proposed based on psychological threshold synergistic.Firstly,the presumption and process description of psychological threshold group evaluation is described.Secondly,the psychological threshold assignment arithmetic of corresponding efficiency indicator,cost indicator,central indicator and interval indicator is structured.Then the evaluation matrix can be adjusted by the psychological threshold assignment.Thirdly,the psychological threshold assignment of group indicators weighting and the adjustment of indicators weighting matrix are put forward.Finally,the adjustment matrixes are aggregation and the result of the group evaluation which is closer to the real value is gotten.Specific example indicates that the method is effective and feasible.Moreover the evaluation results of traditional and new test methods are not equivalent.This method has been expanded to the traditional group evaluation.In response to this shortage of traditional method doesn’t consider the effect on different psychological threshold,preliminary solutions are presented.The method enables subjective evaluation information from group evaluators achieves a better coordination and unity.The rationality and reliability of the evaluation results can be improved.
