【摘要】：评价指标赋权采用FAHP-Entropy耦合定权法,文章在模糊物元分析和灰色关联度分析基础上,建立了基于FAHP-Entropy耦合定权法和灰色模糊物元分析的决策模型,将灰色关联度的大小作为决策依据。该模型采用FAHP法解决了直接采用层次分析法而造成的检验判断矩阵一致性困难的问题;同时Entropy法的引入充分挖掘数据所蕴含的信息;再基于相对熵原理将Entropy法所得权重与FAHP法所得权重进行耦合。实例证明,模型既考虑了决策者的主观意向,又兼顾数据本身蕴含的客观信息,可以较好地解决高速公路改扩建方案决策问题。
[Abstract]:The FAHP-Entropy coupling weight method is used to evaluate the weight of the evaluation index. The fuzzy matter-element analysis and the grey correlation degree analysis are used in this paper. A decision model based on FAHP-Entropy coupled weight method and grey fuzzy matter-element analysis is established. The size of grey correlation degree is taken as the basis of decision. FAHP method is adopted in this model to solve the problem of the consistency of the test judgment matrix caused by the use of AHP directly. At the same time, the introduction of Entropy method to fully mining the information contained in the data; Based on the relative entropy principle, the weights obtained by Entropy method and FAHP method are coupled. An example shows that the model not only considers the subjective intention of decision makers. Taking into account the objective information contained in the data itself, the decision problem of highway reconstruction and extension scheme can be well solved.
