【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.更多还原

【Abstract】 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.更多还原
