应用NGGPS的CAx集成系统的数学逻辑建模与实现

CAx信息表达方式不统一导致 “信息孤岛” 的出现,NGGPS为CAx系统间实现数据和功能的集成统一提供良好的基础平台。采用UML对NGGPS与CAx集成系统进行建模分析,获得集成系统的用例图、顺序图和类图等UML图,结果指出NGGPS对象是NGGPS与CAx集成系统的关键。提出利用逻辑建模依据NGGPS理论构建应用NGGPS的数学逻辑模型,研究使用面向对象技术实现NGGPS对象模型的方法及应用实施。结果表明,该NGGPS与CAx集成系统建模方法具有结构清楚、条理清晰、信息及功能完备、实现容易等特点,且具有良好的扩展性、移植性,方便实现网络化的数据共享与协同操作。

Modeling and realization a mathematical object of CAx integration system based on NGGPS

Non-uniform expression of CAx information arising "information islands", NGGPS provide a good foundation unified platform for CAx data between systems and functional integration. UML is used to NGGPS and CAx integrated system for modeling analysis, use case diagram, sequence diagrams and class diagrams of UML diagrams is designed, results show NGGPS object is the key of the integrated system. Based on the theory of NGGPS using propose method to derived the mathematical formula object of apply NGGPS, research using object-oriented technology to build a mathematical NGGPS object model. It has a layered structure, clarity, information and full-featured and easy to implement, etc., and has good scalability and portability, enabling network-based data sharing and collaboration operations
