Abstract: This paper discusses the Petri net approach to real-time production control. Petri nets were developed to model concurrent and asynchronous systems. Having modelled a machining cell or a production system as a Petri net, one can analyse the effects of controller behaviour on the system before implementing the controller. Petri net principles are illustrated for a machining cell. Observations are made concerning the difference between a Petri net controller and a programmable logic controller for the same application.
Keywords: net control (of an) automated manufacturing cell; real-time production control; programmable logic controller.
