Hierarchical scheduling for large-scale production system based on continuous and timed Petri net model

This paper presents a new hierarchical scheduling method for a large scale manufacturing system based on the hybrid Petri net model, which consists of CPN (continuous Petri net) and TPN (timed Petri net). The automobile production system, which is one of a typical large scale manufacturing system, is focused. Our proposed scheduling method can macroscopically schedule the flow in entire system and can microscopically consider physical constraints, which come from real shop floor.
