Combination Weighting Rating Method for Civil Aircraft Structural Environmental Deterioration

  • 摘要: 针对民机结构环境损伤评定问题进行研究,基于国内研究的现有赋权方法或者偏重主观经验或者过分依赖客观数据的现状,提出基于组合赋权的评定模型方法。该模型采用层次分析法确定主观权重,采用粗糙集理论中决策表的信息熵知识确定客观权重,然后利用向量夹角公式,找到二者之间合理的权重分配系数,实现组合赋权,进而确定总等级,并根据等级间隔对应关系确定检查间隔。最后以某型飞机的重要结构项目为例进行验证分析,效果良好。
