TFT-LCD屬於資本密集與技術密集產業,不但製程複雜且物料搬運活動非常頻繁。2006年底台灣TFT-LCD總產值正式突破新台幣1兆元將邁向第2兆元。TFT-LCD四大主要製程為:陣列製程、彩色濾光片製程、組立製程與模組製程。 設施規劃是一種長期性策略,設施規劃之優劣對彩色濾光片廠績效具相當程度之影響。本研究探討彩色濾光片廠四種設施規劃方案之可行性與績效表現,依據彩色濾光片廠實際資料透過模擬軟體AutoMod建立模擬模式,並利用實驗設計探討佈置型態(流線型佈置或零工式佈置)、白光製程是否共用自動倉儲系統(有無共用區)、投料間隔時間與產品比例等因子對三種績效指標:月產出量、生產週期時間以及搬運距離之影響,以作為方案評估之依據。模擬結果顯示流線型佈置且無共用區之規劃方式為最佳方案,可提供管理者作為決策參考之依據。
TFT-LCD industry is both capital-intensive and technique-intensive. This industry has an output value of more than NTD 1 trillion in Taiwan in 2006. The manufacturing of TFT-LCD consists of four major processes: array, color filter, cell, and model. Facility planning is a strategic long-term decision that is crucial to the performance of color filter fabs. This research studies the feasibility and performance of four types of facility layout of color filter fabs. AutoMod simulation models using data from real fabs were developed and design of experiment was used to evaluate the effect of layout type (i.e., flow line vs. job shop), white-light common area, tact time, and product mix on performance measures of cycle time, transportation distance, and monthly production volume. Simulation results show that flow line without white-light common area leads to the best performance.
