Production scheduling tasks are in general carried out hierarchically and concurrently, such as scheduling for manufacturing systems, for factories and for shops, by different persons and/or organizations. Therefore, a systematic procedure is eagerly required to change the schedules and to keep the consistency among the hierarchical scheduling tasks, when some unforeseen disruptions occur in the manufacturing systems. The objectives of the research are to establish a systematic method for supporting the rescheduling tasks and for keeping the consistency among the various layers of schedules of the hierarchical and decentralized manufacturing systems. Models for hierarchical production schedules are proposed, and rescheduling procedures are also developed based on the models. A rescheduling method is proposed to change the schedules and to keep the consistency among the schedules. A prototype of hierarchical and concurrent rescheduling system is developed and applied to the consistency management problems in the rescheduling tasks.
