Control of Router Nodes in Production Manufacturing Processes*

A generic monitoring and supervisory control scheme is proposed for a router node in manufacturing processes using Discrete Event Systems (DES). The generic model of the router node consists of m production machines with discrete products that place their products at a queue with r slots. The final products of the node will be produced by a (m+1)-th production machine that will be placed at the output of the queue. The final products will be categorized and be sent to m buffers through a distributor. For the control of the system two supervisors and one monitoring supervisor are designed and realized.
