摘要
针对多属性决策问题,提出了一种新的不完备信息下的多属性决策方案。该方案假设属性值采用区间灰数形式来表达信息的不确定性和模糊性,针对属性值的经济属性进行数据预处理,然后将属性权重值进行集结得到方案集的决策矩阵,通过对灰色关联度分析方法进行拓展,提出了基于区间灰数的绝对关联分析,计算各方案与最优方案的绝对关联度,并以此对方案进行排序并择优,通过实例说明了所提方案的可行性。
The basic principle of the grey relational analysis is according to the resemblance of the sequence curves of geometry to judge the intensity degree of each sequence with the feature sequence. Many of the reality of the abstract system cannot accurately be obtained; the multiple attributions are expressed by fuzzy number or the gray interval number. To solve this problem, we propose a decision-making method, which is based on the grey value of the absolute relational degree. In this paper, in order to state our theory an example is analyzed, which is the extension to the traditional grey relational degree model and is with more scalable applicability and practicability.
