Modeling and simulation of loading and unloading scheduling system based on agent and petri net

An integrated method based on multi-agent system and Petri net is introduced to discuss the modeling of loading and unloading scheduling system of automatic storage/retrieval. At first, the model established by the integrated method and its run rules are defined; then, the scheduling elements of the system are classified, and the object class relation are obtained; finally, the APN (agent-Petri net) model of the scheduling system is set up based on the corresponding relations between each object sub-net module and each function agent, which consists of five different function agents. The system model is realized under JADE platform.
