基于复杂网络的产品族模块化过程

用复杂网络描述产品族的结构,运用简单路径搜索算法求出产品层次序列,计算点介数及各级零部件的使用情况;以简单路径作为边中介性的度量,得到边介数;去除中介性最大的连接;计算最佳分类数Q;重新计算边介数.如此反复,可以得到Q函数的分布曲线和聚类图,进而得到模块划分结果.根据零部件使用情况和被标记的结构实体,调整和优化模块划分结果.以工业汽轮机产品族为例,对其结构进行了模块化分析,结果符合实际需要.

Generation Process of Product Family Modularization Based on Complex Network

Main structure of product family can be depicted as a directed complex network.Parameters such as node betweenness,edge betweenness and Q function values were calculated through simple-path detecting algorithm for obtaining distributing curve of Q and clustering dendrogram.Division results can be gained from clustering dendrogram.The results were adjusted and optimized according to parts usage times and entities with sign.As an example,a product family of the industry steam turbine was analyzed with this al...
