基于密度算法和DSM的模块划分方法

A Module Partition Approach Based on Density Algorithm and Design Structure Matrix

针对产品模块化设计中模块划分的问题,考虑到实际过程中设计结构矩阵的多样性,提出一种基于密度算法和设计结构矩阵的模块划分方法,以设计结构矩阵描述零部件间的关联关系,通过n维空间的欧式距离判断各零部件间的联系强弱,利用密度可达原则进行零部件聚类。根据算法参数选用的不同获得不同划分结果,引用模块度准则判别最优的聚类结果作为最终的模块划分方案。最后以汽车起重机上车部分为例说明模块划分过程。

A module partition approach based on density algorithm and design structure matrix is proposed for solving the problem of product modular design, considering the diversity of design structure matrix in actual process. Design structure matrix is utilized to describe the relationship between components, which are clustered according to the density reachable principle, by judging the Euclidean distance of the n-dimensional space. Different partitioning results are obtained while adopting the different algorithm parameters, and the modularity metric is acted as the evaluation index of the clustering results to select the optimal module partition scheme. Finally, the module division process is illustrated by taking the truck crane as an example.
