摘　　要：通过对决策个体提供的信息进行一致性检测,确定群体属性权重区间,从而克服了各决策者给出的属性权重信息不一致给决策带来的困难,使属性权重信息的集结过程充分体现群体的意志和意愿.构造各方案下的各个属性的群效用区间,借助弱优概念,探讨了建立在两两比较基础上的几种弱优关系的内在联系,从而为弱优关系建立的合理性奠定理论基础,最终构造了一种新的交互式的群体多属性决策偏爱强度方法.A new sequencing model for group multi-objective decision-making problem with incomplete information was discussed. The method concentrated on consistency-checking for attribute-weight information provided by decision-makers, which could solve problem that decision-makers always provided different or contradictive weight information. With group＇s total range and group＇s agreed range, group utility range for each alternative under each attribute was constructed. With the help of weak-optimal concept, an interactive preference-strength method was presented.
