| Recently, research in various areas of operations management and scheduling has begun to focus on online optimization and rescheduling in cases where disturbances or changes of the data occur. Especially disruptions may have a considerable impact on the performance of production systems. In this paper a simulation model is proposed and applied to a hybrid flow shop system for the purpose of evaluating different strategies for managing disruptions. The investigated strategies aim both at the shop floor itself and the planning and control of the shop floor. For assessing different strategies for managing disruptions, job oriented and capacity oriented performance measures as well as so-called instability measures are applied. These instability measures enable estimating unfavorable consequences from changing existing schedules based on disruptions. |
