At present, how to evaluate the impact of product design changes in product development process has been a problem to be solved. The research on product design changes has gradually shifted from the component level to the product feature level. Therefore, the components are divided into feature level, and a product feature network is built to analyse the propagation of changes. Because it is not unique to divide features of the component, three-dimensional (3D) entities are used to transit components into 2D features. The strong and weak ties are defined according to the relationship between the divided features, the product feature network is constructed by the divided features and defined ties. Three discrete states of feature nodes are defined based on the change propagation model and the meaning of change propagation index (CPI) in the feature network is proposed. By analysing two types of product feature change propagation and calculating its change probability, the impact of change propagation in the network can be evaluated. Finally, the feasibility of the proposed model is verified by constructing a featured network of a pumping unit and analysing its change propagation.

一种基于产品特征网络的变化传播分析方法

目前,如何评价产品设计变更对产品开发过程的影响一直是一个亟待解决的问题。对产品设计变化的研究逐渐从组件层面转向产品特征层面。因此,将组件划分为特征级别,构建产品特征网络来分析变化的传播。因为划分组件的特征不是唯一的,所以使用三维 (3D) 实体将组件转换为 2D 特征。根据划分的特征之间的关系定义强弱关系,通过划分的特征和定义的关系构建产品特征网络。基于变化传播模型定义了特征节点的三个离散状态,提出了特征网络中变化传播指数(CPI)的含义。通过分析两类产品特征变化传播并计算其变化概率,可以评估变化传播在网络中的影响。最后,通过构建抽油机特征网络并分析其变化传播,验证了所提模型的可行性。
