Many production facilities generate and update production schedules. Rescheduling is necessary because the manufacturing system is dynamic and unexpected events occur. This paper discusses rescheduling policies and how they affect the performance of manufacturing systems. The benefits of proper rescheduling include improved manufacturing system performance with reduced cost due to computational effort (human or computer) and disruptions to existing plans (nervousness). The paper summarizes previous work in this area and also discusses how rescheduling requires methods to solve production scheduling problems. The goal is to help production planners, engineers, and researchers understand the importance of rescheduling and the proper role of production scheduling in dynamic manufacturing systems.
