| Summary: | 碩士 === 元智大學 === 工業工程與管理學系 === 97 === Because of the unique life cycle of TFT-LCD industry and the impact of global financial crisis, the enterprise’s profitability decreases dramatically. Therefore, the competition of continuing building new generation plant is over. Instead, each company examines the advantages and disadvantages of exciting plants to develop its niche products and marketing strategies. Take C Company’s Generation 3 (G3) plant as an example, which hopes that it can decreases the risk of NB, monitor, and TV panels merely by entering the Medium and Small size market. By purchasing new equipments of bottle-neck processes to raise capacity, decreasing product unit cost, and enhancing product competitiveness, the company also thinks about how to make proper facility layout and review the necessity of adjusting the exciting facilities with limited spaces and minimum expenses. Because of the re-layout would result in huge fixed facility expenses (without adjusted), the company would also review the current facility layouts that need to be improved at the same time. In this study, we developed four feasible alternatives by using pairwise interchange method by measuring the total traveling distances. Through the analysis, we could exchange the location of clean process and inspection process and increased its capacity at the same time. It reduced efficiently the unit manufacturing cost of NTD 82.14 per piece, about 10.79%, and it also increased product competitiveness. At the situation of production-then-sale, the facility’s pay-back period could be reduced to 2.4 years. The total moving distance was reduced from 1,865 down to 1,662 meters (i.e., 10.89%).
