A comparison of the AGV control solution approaches using Petri nets
B. Hrúz, Leo Mrafko, V. Bielko · 2003
Different approaches to the solution of the AGV transportation system control are presented in the paper. The first one is based upon the standard Petri nets extended for control. A way of the process control level modeling is shown. It is a basis for the control of the AGV system at the coordination level. An outline of the transportation co-ordination algorithm is described. Another approach is via supervisory control combined with a routing optimization algorithm. Then an approach using colored Petri nets is presented. All approaches are compared.
