中文摘要：

针对大规模定制产品族开发迫切需要计算机管理的问题，提出了一种基于图文法的产品族表达方法。阐述了大规模定制产品族开发的原理，并在功能域和物理域中建立了产品的图模型，在此基础上分别在功能域和物理域中建立了产品族的图文法模型，分析了新产品从功能域到物理域的生成过程。最后以某摩托车产品族为例，说明了模型的应用过程。

英文摘要：

In view of the importance of computer-alded management for development of mass customized product families, an approach to description of product family with graph grammar is presented. The principle of development of mass customized product families is expounded. The graph models of a product are established in functional domain and physical domain. Based on the graph models, the graph grammar models of a product family are established in functional domain and physical domain, and the process of creating a new product from functional domain to physical domain is analyzed. As a case, the description of a motorcycle product family is given to illustrate the application process of the models.
