摘要
考虑不同属性及不同时间对于对象的影响,将灰关联决策模型进行拓展.首先,采用熵权法确定不同时刻各属性的权重,将偏差与灰熵结合确定不同时间的权重.其次将其与邓氏关联分析模型结合,综合集成熵权法及灰色关联决策模型的优点,构建三维动态多属性灰关联决策模型的优化算法.最后将方法运用于河南省农业发展状况评价.结果表明:方法计算简便,分辨率高,且能更好的反映实际.
Considering the influence of different attributes and different time on the object,the grey relational decision making model is extended.Firstly,the entropy method’is’used to determine the weight of each attribute at different times,and the deviation and greyentropy axe combined to determine the weights at different times.Secondly,combining it with Deng’s relational analysis model,and integrating the advantages of entropy weighting.method and grey relational decision model,an optimization algorithm of three-dimensional dynamic multi-attribute grey relational decision model is constructed.Finally,the method is applied to the evaluation of agricultural development in Henan Province.The results show that this method is easy to calculate,high resolution and better reflect the reality.
