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
