抄録

Master production scheduling is the key information to synchronize all business units including production department and sales and marketing department. To make more effective and proactive, materials resource planning(MRP) and capacity resource planning (CRP) must be collaboratively performed in accordance with advanced planning and scheduling (APS) algorithms. In addition, it is necessary to have time buffer to protect from unexpected urgent orders, which disturb the resource usage and cause late deliveries. This paper proposes a calculation method for time buffer that is added to the normal production lead time. The proposed algorithm allows schedulers to make robust schedule for the manufacturing uncertainty.
