【摘要】：针对专家偏好信息为区间数群决策矩阵的多属性群决策问题,提出了一种专家权重确定方法并利用自适应迭代算法实现。首先,给出了区间数和专家群决策矩阵的定义。然后,使用加权几何系数法计算专家综合权重,并通过比较专家个体与专家群体决策矩阵的偏差距离计算出专家的客观权重,经过多次迭代后得到稳定的专家客观权重与专家综合权重。最后,实例验证了该算法的可行性与有效性。
[Abstract]:In order to solve the problem of multi-attribute group decision making in which expert preference information is interval number group decision matrix, an expert weight determination method is proposed and realized by adaptive iterative algorithm. Firstly, the definitions of interval number and expert group decision matrix are given. The weighted geometric coefficient method is used to calculate the comprehensive weight of the expert, and the objective weight of the expert is calculated by comparing the deviation distance between the expert individual and the expert group decision matrix. After several iterations, the stable objective weight of experts and the comprehensive weight of experts are obtained. Finally, the feasibility and effectiveness of the algorithm are verified by an example.
