台灣的汽車產業，由於市場經濟規模小，但又必須滿足市場對於不同車型的需求，在此種少量多樣化的市場結構下，汽車零組件的種類變得更多，相對地庫房備料作業與生產線裝配取拿作業以及物流供應，也變得更加複雜。因此，汽車生產線的供料模式關係到生產流程是否順暢，亦關係到整體生產營運成本與效率，是汽車生產製造的關鍵要項之一。故針對汽車生產線供料模式更進一步的研究與改善，將有助於台灣汽車產業在嚴峻的市場競爭環境下生存發展。 隨著科技的進步與精實生產思想的應用，汽車製造廠的生產線物料供應模式亦持續演變改善。就軟體方面而言，從早期以人工作業方式進行訂單生產排程，逐漸由電腦整合系統來取代；就硬體方面而言，從早期以叉車或拖車頭方式進行物料運送，逐漸採行無人搬運供料系統自動運補來取代。 本研究乃藉由對個案公司多年來在汽車生產線供料模式不斷改善的過程，以探討物料供應及時化與自動化，並達到品質防錯的改善。以期將研究結果推展應用於汽車產業成車廠生產線及汽車產業成車廠零組件庫房，所得結論如下： (1) 全面導入AGV搭配成台份物料台車供料(Set Parts Supply)模式持續改善 (2) 教育訓練強化持續實施。;With the market scale of economy is small, as well as the necessity of fulfilling the market demand on various types of vehicle, the market structure of Taiwan automobile industry has been limited diversification. Under such situation, the automobile manufacturing needs a greater variety of parts, meanwhile the parts preparation in warehouse is getting more complicated, so is picking parts in assembly line or material handling. Thereupon material supply model of assembly line has become a critical issue of automobile production, since it relates not only to smoothness of production process but to the total cost and efficiency of production. To implement further study and improvement on the issue will help enterprises survive from fierce market competition. As the science and technology proceeded, the automobile manufacturer continually improved the way of distributing materials to production line based on lean production method. On software side, they applied computer integration to replace manual basis for production programming. On hardware side, the AGVS (Automatic Guided Vehicle System) could be used for parts delivery in stead of fork lifts and electric carts. The dissertation investigates case company on the gradual improvement process of material supply model of automobile assembly line for the past many years, to study how to supply materials just in time and automatically, and apply it to the similar production process. The conclusion is to adopt set parts supply with AGV for materials feeding to assembly line, and keeping on improving process.
