| Summary: | 碩士 === 國立臺灣科技大學 === 工業管理系 === 101 === Intense global competition and declining profit have caused most Thin Film Transistor - Liquid Crystal Display (TFT-LCD) manufacturers to increase their competitiveness by improving productivity and reducing cycle times. Color Filter (CF) is one of the key components of TFT-LCD. In this research, an Advanced Planning and Scheduling (APS) system was developed with Microsoft Visual Basic for Application (VBA) to automatically generate production schedules for color filter fabs. This system can assign orders to production lines, plan order release time, and balance the equipment loading by the implementation of five major modules: order priority module (OPM), lot release module (LRM), line selection module (LSM), workload accumulation module (WAM), and workload balance module (WBM).
Experimental results indicated that APS can significantly reduce manual scheduling time while maintaining the quality of scheduling results. Compared to manual operations, it can save more than 85% of scheduling time and the quickness is especially important when rescheduling is needed due to production uncertainties such as equipment breakdown or material shortage. Production controllers can use this APS to generate initial schedule and make adjustment based on experience.
