基于灰色层次属性模型的评估指标综合方法

Synthetic Evaluation Method Based on Grey Evaluation Method and Analytic Hierarchy Model Theory

层次分析法在无结构决策的应用中存在一致性判断复杂问题以及专家评价不客观的问题。针对以上问题,提出基于灰色分析方法与层次属性模型结合的新方法,将来自于相关研究领域内专家的给出的指标相对属性权重评价信息以层次属性模型方法进行群组分析处理,获取指标相对权重,应用灰色评价方法整合专家给出的指标评价信息,将获取的相对属性权向量与灰色权矩阵综合后投射到评分区间得到最终评价结果。所提出方法可以快速计算得到评价结果,相比传统方法更为客观且易于实现。

To solve the problems that judging matrix is complex and evaluation information from experts is not always objective in Analytic Hierarchy Process （AHP） method during the unstructured decision making application, a new synthetic evaluationmethod based on grey evaluation method and analytic hierarchy model theory （AHM） isproposed. GroupAHM method is used to judge the relative weight between any two of indexes based on relative weight evaluation information from experts in the relevant research field and grey evaluation method is used to synthesize the index evaluation information from experts. Evaluation result is obtained by mapping synthesizing result of relative property weight vectors and grey weight matrixes to scoring range. The new method is more objective and realistic than original ones, Finally, the method was proven feasible with the help of examples about guidance and control system evaluation of vehicle.
