Summary
This paper presents a hierarchical decentralized scheduling method for a real-time production line control, which consists of a strategic level scheduler(SLS) and operational level schedulers(OLS). The SLS aims at making a schedule referenced by the OLS. The schedule solved by the SLS satisfies some constraints, and is generated by a schedule editor on the Flexible Planning System(FPS). The OLS aims at the real-time control of the production line and is based on the know-how of the supervisor.
This hierarchical method is evaluated by discrete event simulations. The results show that this method is more useful than the practical operation subject to minimizing lateness and tardiness to a dynamic environment such as failures of machines or AGVs.
