一种AHP中群体决策逆判问题的新方法

为了研究AHP中的逆判问题,利用模糊关系对AHP中群体决策的一致性给出了判断方法,即由一致性系数构造模糊关系矩阵,对其一致性进行分类,当分类情况基本一致时,则专家们给出的判断矩阵是公平公正的。通过算例验证了方法的可行性,并对AHP中的逆判问题提出了一种新算法,定义了新的一致性系数,经算例验证与相关文献的结果是一致的。

New Method for the Opposite Judgement Problem of Group Decision in AHP

In view of the problem of the opposite judgement in AHP,a new method of judgement for the consistency of group decision by using fuzzy relation matrix is offered and the consistency of group decision is also classified.When the classification is in consistency,the judgement for the matrix is proved fair.By testifying the feasibility of the method through practical examples,a new algorithm for opposite judgement in AHP defines a new consistency coefficient.The result is proved to be in consistency with the findings in correlate reference through practical examples.
