摘　　要：针对熵权法下属性客观权重的分散度不高的问题,提出了基于调节系数的改进的判断矩阵标准化处理方法.以不同决策者对相同方案同一属性的评价值为基础,根据数据稳定性与属性权重之间的正相关关系,提出以属性评价值的熵作为数据稳定性的度量,并由该熵值确定属性客观权重的方法.同时,依据群决策者对于属性的主观偏好值的稳定性及其平均值之间的关系给出了属性的主观权重.最后通过算例表明了所提出方法的可行性与实效性.To increase the dispersion of the objective weights derived from entropy weighting method, an improved approach is presented for normalizing the decision matrix based on adjustment coefficient. The entropy of attribute evaluated values is used as a measurement of data stability, and the objective weights of attributes are determined through their entropies according to the positive relationship between data stability and attribute weights based on the same alternative and attribute but different decision-makers. Subjective weights of attributes are obtained on the basis of the stability of subjective preference values given by group decision-makers and average of them. Finally, an example is given to verify the feasibility and rationality of the proposed method.
