1.  TYPES OF NETWORKING
Computer-integrated manufacturing(CIM) is a philosophy of integrating hardware and software in such a way as to achieve total automation. Although each company has its own idea of what CIM really means, most follow a pattern similar to that in Fig.1. In this diagram, dedicated processing tasks are shown distributed around a factory. As computers are further removed from the actual manufacturing area, their function shifts from real-time control toward supervision.

1 网络种类
 计算机集成制造的原理就是结合软件和硬件实现制造过程完全自动化。尽管根据不同CIM的需要，每种计算机都有自己的设计形式，但时大多数形式类似于图－1。图－1显示，集中处理任务被分配给整个工厂。随着计算机进一步远离生产现场，它们的功能已经由实时控制转向管理或监督。
