On the application of Petri net supervisory controllers in dynamic reconfiguration of medical emergency resources

In this paper, we show how Petri net (PN) based supervisory controllers can aid and assist in hospital planning and emergency response system resource management. We model the problem of medical resource assignment in normal and emergency hospital operations Petri net controllers. We then present a method to show the controller reconfiguration needed when the available resources become unavailable or the medical system priorities change. The contribution of this paper is that it relaxes the assumption of fixed medical resources and specifications in the control of medical resources as assumed by previous literatures.
