基于超图理论的产品族规划方法

将超图理论与质量功能配置相结合,用关联超图描述了产品族规划的复杂信息映射过程,将关联超图中的主输入路径,即同一域中差异化信息向质量屋的左端或下端扩展,将关联超图中的从输入路径,即不同域之间的信息映射通过增加质量屋的行或列来扩展,对产品规划工具———质量屋进行了改进,提供了能够同时进行一族产品规划的扩展质量屋。借助扩展质量屋,描述并实现了客户差异化需求向产品族工程技术特征的信息映射。

An Approach to Product Family Planning Based on Hypergraph Theory

This paper proposed a new approach to extend the house of quality (HoQ) in order to fulfill the product family planning for mass customization. Firstly, hypergraph (HG) theory and QFD were brought together and the information mapping processes between the adjacent stages of a product family development cycle were described through a relational hypergraph (RH). Secondly, primary-input driven paths in a relational hypergraph, which represent different information at the same domain in a HoQ,were placed on the left or at the bottom of a HoQ, and secondary-input paths in a relational hypergraph, which represent the different information at the adjacent domain in a HoQ,were placed at the middle array of a HoQ, an extended HoQ (EHoQ) was obtained according to the method described as above, which provides the tool of planning a batch of products at the same time. Finally, the process of translating a group of different customers' needs into engineering characteristics is illustrated by means of an EHoQ.
