摘要
本文用区间数表示群体判断，建立了上三角形式的区间数群体判断矩阵，从而利用文［１］的结果计算相应的区间数权重，并对文［１］中群体判断的置信度λ＿（ｉｊ）的确定方法进行了改进，使权重的计算更科学，决策结果更符合客观实际。
h In this paper the upper triangular group judgement matrix is established by interval numbers and the corresponding weights are calculated according to the result of[1],and as well the determination of the confidence degree λ_(ij) for the group judgement introduced in [1] is improved, which makes that the calculation for weights is more reasonable and the decision must be moresuitable for the objective reality.
