This paper discusses the Petri Net approach to real time production control. Petri nets were developed to model concurrent and asynchronous systems. Having modeled a machining cell or a production system as a Petri net, one can analyze the effects of controller behavior on the system before implementing the controller. Petri net principles are illustrated for a machining cell being implemented in the Manufacturing Automation Laboratory at Rutgers University. Observations are made concerning the difference between a Petri Net Controller and a Programmable Logic Controller for the same application.
