For the purpose of semiconductor manufacturing TAT (Turn Around Time) reduction, throughput variability reduction for each machine has been requested. For this purpose, this research presents a new dispatching method by calculating number of input volume for each product automatically with a normalized index that quantifies production capability for each machine to manufacturing plan. As a result, the proposed method reduced arrival variability of the bottleneck machine by 33 to 51% to reduce TAT by 13 to 37%.
