一种具有不同形式偏好信息的群决策方法

给出了一种具有不同形式偏好信息的群决策方法·描述了在群决策中决策者可能给出的效用值、序关系值、互反判断矩阵、区间数评价值、模糊语言评价值和模糊互补判断矩阵等 6种不同形式的偏好信息 ,并给出了将不同形式的偏好信息均转化为模糊互补判断矩阵形式的计算公式·基于近年来最新发展的OWA算子给出了集结各决策者的偏好信息和方案优选的方法 ;最后给出了一个算例·

A Method for Group Decision Making Problems with Different Forms of Preference Information

A method for group decision making with different forms of preference information was proposed. Six forms of preference information provided by decision maker in group decision making, such as utility value, preference ordering, multiplicative judgement matrix, interval numbers, linguistic assessment value and fuzzy reciprocal judgement matrix, were described. The computational formulas were given to uniform six different forms of preference information into the form of fuzzy reciprocal judgement matrix. Based on OWA (Ordered Weighted Averaing) aggregation operators, an approach was presented to aggregate the preference information provided by every decision maker and select the most desirable alternative(s). A numerical example was used to illustrate the use of the proposed method.
