| 摘 要： | 参考类似机型的经验是我国目前民用飞机研制的主要途径之一。为了更好地借鉴国内外类似机型的经验,本文提出了一种基于信息熵的类似机型确定方法,该方法应用信息熵理论,直接通过类似机型数据所蕴含的客观信息计算各属性的权重,消除了依靠人为指定权重的主观因素影响。在此基础上,给出了包含有不精确信息属性的相似度的计算方法,最后应用支线飞机实例进行了验证,表明该方法具有较高的客观有效性。

| Abstract: | CBR(Case-Based Reasoning)has been used widely in many fields,and case retrieval is the focus of CBR system.The quality of case retrieval is influenced by the uncertainty attributes and the weighted decision method of attributes.This paper proposed a method of attribute weighted decision based on entropy of information,which can obtain attribute weights from data of the existing cases in order to reduce the influence of the human subjectivity.Further,a method of case similarity is provided for the cases that include uncertainty attributes.Finally,as an example,the method was verified using regional jets,and the result shows that it is objective and effective. |
