基于主客观组合群决策的权重区间确定方法

摘要

This paper puts forward a method to determine weight interval. The steps are as follows： forming weight interval through combining subjective weights given by several experts with objective weights by several quantitative methods;analyzing the superposition relation of subjec- tive weight intervals and objective weight intervals;circularly optimizing weight intervals according to the calculation results of the confidence and accuracy of weight intervals. Finally,it demonstrates the science and maneuverability of this method by using an example.%提出了一种确定权重区间的方法,即将由多位专家确定的主观权重和用多种方法计算的客观权重相结合,形成权重区间,通过分析主客观权重区间的重合关系,计算权重区间的置信度和精确度,据此对权重区间进行循环优化。最后用算例表明了该方法的科学性和可操作性。
