• Resumen

  • This paper presents a dynamic releasing scheme (D-Roll), which determines when and which wafer lot should be released into the shop floor using the concept of rolling correction. With real-time information from manufacturing execution system (MES), the priority and the time point of releasing can be adjusted dynamically. The performance measures used in this paper are throughput, cycle time, WIP (Work-In-Process), turn-rate, delivery, and bottleneck utilization. The results show that the proposed dynamic releasing scheme is better than other conventional strategies (WIP to bottleneck control, starvation avoidance, fixed-WIP, and uniform loading).
