在群体决策过程中,即使达到共识水平,个体偏好或群体偏好也可能存在矛盾的成对比较。为了避免这种矛盾现象,本文提出了一种基于近似传递性的互惠偏好关系一致性阈值,以保证群体决策中具有互惠偏好关系的方案排序的可靠性.分析了互惠偏好关系的自然不一致性或不传递性,并通过数值实验进行了验证。然后,利用数值实验的结果,近似的基于传递性的一致性阈值的基础上,最小化的第一类错误,第二类错误和总错误的统计目标。此外,一个关于个人互惠偏好关系和群体互惠参考关系的传递性检查过程被纳入群体决策过程。为便于应用,给出了一个集成传递性检验的群决策模型。以高速铁路线路车站选择为例,说明了基于近似传递性的一致性阈值在检验群决策互惠偏好关系传递性方面的必要性。
In a group decision-making process, contradictory pairwise comparisons may exist in individual preferences or the group preferences even though the consensus level is reached. To avoid such a contradictory phenomenon, this study presents an approximate transitivitybased consistency threshold for reciprocal preference relations to ensure the reliability of the ranking of alternatives with reciprocal preference relations in group decision making..The natural inconsistency or intransitivity of reciprocal preference relations is analyzed and verified by numerical experiments. Then, using the results of numerical experiments, approximate transitivity-based consistency thresholds are introduced based on the objectives of minimising the Type I error, Type II error and total error in statistics. Moreover, a transitivity checking process regarding individual reciprocal preference relations and group reciprocal reference relations is incorporated in the group decision-making process. A transitivitychecking integrated group decision-making model is given for application. An example about the station selection for high-speed railway line is provided to show the necessity of the approximate transitivity-based consistency threshold in checking the transitivity of reciprocal preference relations for group decision making.
