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。

关键词: 基于实例推理, 模块化变型设计, 自组织映射网络, 加工中心

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 of the proposed method was revealed.

Key words: modular variant design, case-based reasoning (CBR), self-organizing maps (SOM), machine center
