摘要
研究了属性权重完全未知、属性值为区间数且对方案有偏好的多属性决策问题 ,提出了一种基于相离度的求解属性权重公式 ,并利用区间数比较的可能度 ,对决策方案进行排序 .该决策方法既能充分利用规范化评价的先验模糊信息 ,又能尽可能地满足决策者的主观愿望 ,且概念清楚、含义明确、易于计算机或计算器上实现 .
This paper studies uncertain multi-attribute decision making problems with preference information on alternatives,in which information on attribute weights is unknown completely and attribute values are interval numbers,and presents a formula based on deviation degree for deri- ving attribute weights.A new method based on possibility degree is given to get the priorities of alternatives.The method can sufficiently utilize the normalized fuzzy evaluation information and meet the requirements of decision-maker,and can also be performed on computer easily.Finally,a numerical example is given to show the feasibility and effectiveness of the developed method.
