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.
In view of the fact that the objective weight of attribute under the entropy method is not high, we propose an improved standardization method of judgment matrix based on the adjustment coefficient. Based on the evaluation value of the same attribute of the same scheme by different decision makers, Attribute weight, we propose a method that uses the entropy of the attribute evaluation value as a measure of data stability and determines the objective weight of the attribute from the entropy value.At the same time, according to the stability of the group decision-maker’s subjective preference value And its average value gives the subjective weight of the property.At last, an example is given to show the feasibility and effectiveness of the proposed method.
