The realization of scheduling strategies in the material flow system of FMS

At the beginning of this paper, various part scheduling strategies used in the material flow system of FMS are discussed. Then, we model the part flow system with object-oriented high-level Petri net (OPnet) approach. The model is understandable and has the advantage of modularity and reusability. Various strategies can be used easily and flexibly based on the model. In the last section, the approach of realizing the various strategies is discussed.
