摘要
提出了一种基于粗糙集分类来判断群决策专家个体可信度权重的新方法。先根据专家给出的判断矩阵分别按照条件属性值和决策属性值将方案进行分类,再用概率分布函数来考察每个条件属性类在决策属性类中的分布情况,算出与均匀分布时的概率分布函数的距离和,将各个专家判断矩阵的距离和进行归一化处理,以此作为群决策专家个体可信度的权值;最后用算例给出了该方法的可行性和有效性。
A new method based on rough set calssification for determing the personal reliability weight of decision makers is proposed. First classify the projects by conditions and decision attributions, next think of the distribution of conditions in decision by probability distribution function, and sum up the distance between the distribution and the averagely distribfition, and then canlulate the weight. This method is illustrated by an example.
