摘要
针对模糊群体多属性决策问题,提出一种新的灰色多属性决策方法.该方法依据一般的灰色关联分析方法的基本思路,将灰色关联度和欧氏距离有机结合,构造出一种平均相似度对方案进行评价.平均相似度同时反映了方案与正负理想方案之间的位置和数据曲线的相似性差异,其物理意义更加明确.最后通过算例表明了所提出方法的可行性和有效性.
The decision-making method for the grey multiple attribute decision-making problems is presented.Firstly,a new kind of similar degree between two interval grey numbers is established by combining the Euclidean distance with grey correlation degree to appraise the scheme.Then,the average similar degree is constructed,which reflects the distance and the difference of data curves among a selected scheme,the ideal solution and negative ideal solution.Thus,this method has clear physical implication.Finally,an example is given to show the feasibility and effectiveness of the proposed method.
