虚拟企业中的信息集成技术

研究了利用Ｉｎｔｅｒｎｅｔ和分布对象等相关技术实现在虚拟企业中集成制造信息,这种集成涉及网络通信、产品建模和软件互操作方面的国际标准：Ｉｎｔｅｒｎｅｔ和ＷＷＷ、ＳＴＥＰ、ＣＯＲＢＡ,三种技术的综合应用为面向Ｉｎｔｅｒｎｅｔ的制造信息集成和制造软件互操作提供了基础,成为成立虚拟企业的基本技术条件。

TECHNIQUE OF INFORMATION INTEGRATION IN VIRTUAL ENTERPRISES

For sharing knowledge and resources in global manufacturing enterprise s, the technique of information integration must be extended to face network env ironment. For the requirement of network manufacturing, the author focused on th e implementation and application technology of manufacturing information integra tion with the utilization of Internet and distributed object technology. With the standards of network communication, product data modeling and softwar e interoperation, the integration model was designed. WWW(VRML/XML) is used for the representing and exchange of manufacturing information, STEP is used for pro duct data modeling and CORBA is used for software system interoperation. Using a bove three technologies, the information integration in Virtual Enterprises over the Internet will be achieved in software code and semantic level.
