摘要
针对方案的属性值为区间数并且属性权重完全未知的多属性决策问题,提出了一种新的多属性决策方法.基于联系数理论,首先构建了联系数之间的距离公式;其次引入方案间相对相离度和相对相离度矩阵等概念及其计算公式;然后将区间数属性值转化为联系数表示,利用所提出的概念和公式进行多属性决策,从而得到方案间的优序排列.决策方法直观简单,避免了属性权重的计算.最后给出实例说明了提出的方法具有合理性和有效性.
For a multi-attribute decision making problem,in which all attribute values are interval numbers and attribute weights unknown,a multi-attribute decision making method is presented.Based on connection theory,distance formula between connection numbers firstly is constructed.Secondly,the concepts and formulas for relative incidence degree and incidence comparative matrix are introduces.Then,through transforming the interval number into connection number,ranking alternatives is determinated by the concepts and formulas presented in this paper.This method is direct and simple,and avoids calculation of attribute weights.Finally,an example is given to demonstrate the rationality and validity of this decision making method.
