摘要
目前模糊理论以及层次分析法已经广泛运用于风险分析中,这两种方法都涉及因素的权重分配问题。在应用层次分析法的基础上,引入欧氏距离来描述各位专家所得权重的相似程度的大小。经过实证研究,利用欧氏距离在淘汰某些专家所得权重后,一定程度上减少了权重确定的主观性,使得权重的分配更加合理。
At present, fuzzy theory and AHP have been used widely in risk analysis. And the proportion problem of the factors is inevitably involved in these two methods. On the basis of the application of AHP, this paper introduced the euclidean distance to describe the similar extent of the proportion made by experts. A case study indicates that, at a certain extent, subjectivity of proportion problem is reduced, and the factors＇ proportion is optimized after eliminating some experts＇ results by using the euclidean distance.
