碩士 === 中原大學 === 工業與系統工程研究所 === 99 === A failure planning strategy may result in broken credit of a company. To improve this issue, An AutoMod simulation model is constructed for real-world 4.5th-generation (4.5G) Thin Film Transistor - Liquid Crystal Display (TFT-LCD) Color Filter (CF) fabrication plants in this study. The characteristics and data of customer orders, production facility, material handling tools, and warehouse (also called stocker) are collected from real plants. Using fishbone analysis, sensitivity analysis and experimental design, a series of simulation experiments are conducted and the resulting simulation model is representative to the CF plants. Advanced strategies of planning and scheduling are developed and tried to implement in color filter fabs to effenciently enhance the capacity. Furthermore, a look-ahead release planning strategy is implemented in the model to evaluate the key performance index of productivity, equipment capacity and lead time. Better alternatives leading to higher system throughput can be identified in system simulation before its real implementation in the fab. As the simulation model is complex and had different parameters representing the operation details in the plants, it is of interest to justify the effects of these parameters to the key performance indicators such as system throughput. Decision makers can conduct what-if analysis by simulating and evaluating different improvement alternatives before any policy is applied to the shop floor and ensure the success of the policy before it is really implemented.
