支持产品数据动态管理的数据-过程互动模型

根据产品设计过程的实际特点，提出一个数据－过程互动模型（DPIM，dsata and pocess interplayed model），该模型能有效地描述产品数据和设计过程间的动态交互行为，基于该动态模型，设计过程的描述和执行能适应设计数据的动态变化，设计数据和设计过程的管理紧密地集成一起，由于设计数据的变化和过程的定义执行是互动的方式交织进行的，所以该模型能较好地描述产品设计过程的动态性。

A Research on Data-Process Interplayed Model for Product Data Dynamic Management

Based on the analysis of the nature of design process, DPIM (data and process interplayed model), which can effectively describe dynamic relations between the design data and the design process, is established. By using this model, the definition and the execution of design process can adapt to the changing data requirements. and the design data can be produced and perfected within the design process. As a result, the design data and the design process can be managed in an integrated way. Since the data and the process change in an interplayed manner, this model can better reflect the dynamic nature of the product design process.
