Product module partition method based on edge betweenness agglomeration characteristic of complex network

Module partition is the key part of product modular design. The existing methods have the shortcoming of relying on functional structure and complex algorithm. In this paper, the product module partition method is put forward based on the edge betweenness agglomeration characteristic of complex network. The network reflecting the product assembly structure is constructed by taking the parts as nodes and the connection between any two parts as edge. The definition and agglomeration characteristic of complex network edge betweenness is introduced. The edge betweenness search algorithm of undirected acyclic network is given. The proposed method is illustrated and validated by taking the automobile engine as an example.
