研究具有不同形式偏好信息的群决策问题。在描述效用值、序关系值、模糊判断矩阵和 AHP判断矩阵等 4种形式偏好信息的基础上 ,首先给出将不同形式的偏好信息转化为模糊判断矩阵形式的计算公式 ,然后基于 OWA算子给出集结各决策者偏好信息和方案优选的方法 ,最后用一个算例证明了所提出方法的有效性 Study on Group Decision Problems with Different Forms of Preference Information. Based on the description of four kinds of preference information, such as utility value, ordinal value, fuzzy judgment matrix and AHP judgment matrix, the formulas for transforming different forms of preference information into fuzzy judgment matrix are given first. Then, based on OWA operator Given the method of compiling the preference information and scheme preference of decision-makers, and finally using an example to prove the validity of the proposed method
