In our model, the complete manufacturing system is viewed as composed of three autonomous components. These are:

Management/Business subsystem. This subsystem is responsible for carrying out entire business operations of the factory and for making out essential high level global decisions to trigger the activity in other subsystems.

Computer-Aided-Design (CAD) subsystem. In this subsystem design activity is performed and the finished design is made accessible to other subsystems by creation a shared CAD database.

Planning and Control subsystem. All shop floor operations lie within the domain of this subsystem. Besides operational control, entire factory level strategic and tactical planning are also the responsibility of these subsystems.

The three subsystems above are linked to an interconnection subsystem; in contrast to some existing proposals for CAD/CAM integration, in our architecture; there is no integrated data or knowledge base in the system. The local data and knowledge bases are organized using object oriented approach.

Most of the previous researches follow either centralized or hierarchical approach for the design of planning and control subsystems. In the hierarchical approach a computer at a higher level of control sends commands to and receives information from computers at lower levels of control. This creates a master/slave relationship among different levels of control. Consequently, it is not possible adequately to deal with the issues of fault tolerance, extensibility and dynamic control.

In the fully distributed architecture suggested by us, there are no multiple levels of control. Logical cell controllers are equal decision makers and perform all planning in a cooperative manner. For each cell there is a closely coupled cell controller. The information of a cell is readily accessible to the cell controller. The cell controllers are interconnected via local area network with broadcast capability.
