| 摘 要： | 为提高模块变型设计的效率和准确性,提出了一种基于实例推理技术的模块化变型设计方法。将实例推理技术(case based reasonin, CBR)应用到模块化产品的变型设计中,CBR技术实现相似产品设计方案与相似结构模块的检索和选择,采用基于特征的实例框架表达方法,使用自组织映射神经网络,实现实例的可视化聚类,在此基础上构造分层多级实例库。采用基于差异和规则的实例修改方法,提高了CBR的检索速度和准确度。最后以卧式加工中心的变型设计为例,说明了该方法的可行性和实用性。

| Abstract: | In order to improve the efficiency of modular variant design,a method of case-based reasoning combined with modular variant design(CBRMD)was put forward.Case-based reasoning(CBR)technology was used in modular variant design,similar case of product and structure module was retrieved by CBR,self-organizing maps(SOM) networks were employed to cluster past cases,and then the layered case base was constructed with clustered cases.Finally,through the example of modular design of machine center,the practical value... |
