【摘要】 通过对产品开发过程的分析 ,指出了并行产品开发过程的必要性。基于面向对象的技术 ,建立了并行设计与过程开发的产品与过程模型。在所建立的对象模型基础上 ,结合工装 CAD的设计过程 ,开发了以 PDM为集成框架的工装 CAD管理系统 ,并给出了系统的实现方法。采用该系统 ,不仅增强了对产品数据信息的管理能力 ,也大大提高了设计效率 ,缩短了产品的开发周期更多还原

【Abstract】 In this paper, the necessity of designing prod uct in concurrent way is proposed by analyzing the product development process. Based on the object-oriented technique, the product and process model is establ ished. According to this model, a frameworks system integrating the technique to ol CAD system with PDM is developed and the implementation method is given. The capability of product data management is enhanced, the design efficiency is impr oved and the design time is shortened to great extent by means of this system.更多还原
