基于产品数据管理的产品和开发过程集成方法

为支持集成的产品和过程开发 (IPPD) ,建立了表达产品开发过程的功能、行为、组织和信息要素的过程模型。用产品模型数据交换标准 (STEP)建立了产品与开发过程间的关系 ,用面向对象方法建立了产品和开发过程的集成机制。开发了支持 IPPD的工程框架系统 ,它由产品数据管理(PDM)层、开发工具层和过程管理层组成。 PDM层提供了有效的集成信息环境 ;开发工具层由许多单独的产品开发软件组成 ,这些软件封装在 PDM系统中 ;根据建立的过程模型 ,过程管理层仿真和控制产品开发过程 ,并在工程框架系统中有效地实现了产品和开发过程集成

Integration methodology for product and development process based on product data management

Process models for integrated product and process development (IPPD) were constructed to represent the functional, behavioral, organizational and informational perspectives of the product development processes. The standard for the exchange of product model data (STEP) was used to develop the relationships between products and the development process. A mechanism to integrate the product with the development process was presented using the object oriented approach. An engineering framework system to support IPPD was then developed which includes a product data management (PDM) level, a development tool level and a process management level. The PDM level supplies an integrated information environment. The development tool level includes many stand alone software tools for product development encapsulated in the PDM system. The process management level simulates and controls the product development process according to the process models. The product and the development process are successfully integrated in the engineering framework system.
