摘    要:引入一种反映决策者心态的指标-区间数,用区间数表示因素的权重及其评估矩阵,并给出了因素的阈值区间数.定义了一滤波器,并结合阈值区间数有效地剔除了偏差较大的评估区间数.最后给出了区间数的二次综合评估模型,并定义了新的区间数排序方法.实例分析证明该模型能有效地克服由于决策者的模糊性而带来数值不确定性.

关 键 词:模糊决策  二次综合评估  主观信任  区间数  阈值  滤波器

Abstract:Interval number, an index to reflect decision maker' s attitude, was introduced in this paper. The weights and evaluation matrix of factors were presented by interval numbers, and the threshold value of interval numbers was given. Defining a filter and combing threshold value of interval numbers, the model can effectively e liminate those assessment interval numbers,which have larger deviation than others. Finally, a twice comprehen sive evaluation model based on interval numbers was proposed, and a new interval number sequence method was provided. The example analysis shows that the model can to the fuzziness of decision maker. overcome the uncertainty of the numerical value owing
Keywords:fuzzy decision  twice comprehensive evaluation  subjective trust  interval numbers  threshold value  filter
