中文摘要：

为有效应对现有群决策偏好一致性检验方法的系列弊端,针对目前群决策情景所展现的决策导向多元、方案属性构成迥异和偏好结构复杂等特征,在解析群决策偏好一致性判定复杂性、刻画群决策偏好信息表征假设情景的基础上,对常规多属性群决策问题进行公理化描述。依据从方案层面到属性层面的整体决策信息判定策略,给出决策导向层面的整体判断偏好一致性检验方法、决策群体偏好类型识别方法、同种偏好内部及偏好间累积判断偏差求解方法、偏好整体相对一致性检验方法和多轮次非一致性决策信息调整策略。案例应用结果表明,上述所构建的方法和策略有效、可行,能够为决策导向多元、备选方案差异显著情景下的混合结构偏好一致性检验、调整与集结提供借鉴。

英文摘要：

In order to efficiently cope with a series of defects of the consistency check method of group decision,the complexity of consistency judgement of group decision preference is analyzed and hypothetic scenarios of the group decision preferential information representation are described according to the characteristics of diversified decision-making orientation,different plan attributes and complex preferential structures exhibited by group decision-making scenarios.Based on that,an axiomatic description is conducted of conventional multi-attribute group decision issues.In view of the overall decision-making information judgment strategies from the perspective of plans and attributes,the overall judgment and consistency test methods of preference,recognition methods of group decision preference types,solutions to judge the deviation within and between preferences,overall relative consistence test methods of preference and multiround inconsistence decision information adjustment strategies are provided.Results of the case study suggest that all the above methods and strategies are valid and feasible,and can provide references for the consistence test,adjustment and integration of the composite structure preference under the scenarios of diversified decision orientation and significant alternative differences.
