基于复杂网络的产品族结构建模及模块分析方法

MODELING OF PRODUCT FAMILY STRICTURE AND MODULE ANALYSIS METHOD BASED ON COMPLEX NETWORK

将复杂网络理论应用于产品族结构建模中,提出产品族结构的零部件关系网络模型,零部件作为网络的节点,零部件之间的隶属关系作为网络的边,并在此基础上演化出产品族结构的模块关系网络模型。运用简单路径搜索等算法对各个节点的介数、次数和产品数等参数进行计算和统计。通过分析和比较这些参数,提出基于产品族结构网络模型的模块分类方法。在实例研究中,以某企业工业汽轮机产品族为例对上述方法进行验证。在分析网络模型相关参数的基础上,区分基本模块、必选模块和可选模块:寻找产品族中的关键模块并分析模块类型的转变是产品族演化的基础和关键。

Applying complex network to product family structure modeling, network model of parts relationship for product family is presented. Parts and components are the nodes of the network and subjection relations of parts and components are the edges. Network model of module relationship is evolved. Parameters of the networks such as betweenness, usage times and product numbers of each node are calculated via simple path searching algorithm. Through analyzing and comparing these parameters, a method of distinguishes various modules based on network model is presented. As an example, a product family of the industry steam turbine is researched with this algorithm and some useful results of analyzing module characters are obtained. Distinguishing basic modules, must-selected modules and may-selected modules is an important work. The idea can be applied in looking for key modules and analyzing conversion of module types, which is the base and key for researching evolvement of product family.
