| Summary: | 碩士 === 元智大學 === 工業工程與管理學系 === 93 === In wafer fabrication, the queue time consumed most of the cycle time. The APS simulation model was developed to support the wafer fabrication automation production system as an efficiency solution.
In this study, the AutoSched APTM was used as simulation tool. In this new production priority modify model, consider the customer’s require due-date and the forecast wafer out date by simulation model. This model will apply the new setting priority into dispatching system to access the objective of production control.
There are two phases in this study. In phase one, the simulation model was built and validated by real data. In phase two, the new priority setting model was linked with dispatching system as an APS to achieve the high on time delivery rate.
After real data application, this new production priority modify model was proved can reduce the production cycle time by 0.84 day and enhance on time delivery from 93.7% to 97.6%.
This study had successful in whole wafer fabrication production control by APS Simulation Model. It really find out the simply method to direct control the production and on time delivery.
