近幾年來，雲端應用已是非常普遍現象，雲端計算是推動巨量資料( Big Data)分析與與開放資料界面等關鍵服務之營運模式，同時在近來熱門話題如物聯網、智慧城市、工業4.0等扮演著重要角色。 本文研究目的係探討台灣傳統機械業製造廠使用雲端服務的狀況及如何運用雲端服務創造效益；本研究是以F公司為研究個案，研究個案如何透過雲端應用增加企業效益、顧客滿意度,在當前環境下如何以擬訂之策略增加競爭對手門檻及產品區隔市場，並符合現在趨勢，以迎接工業4.0雛型做準備。 本研究透過個案資料收集、相關文獻探討及個案執行人員訪談，探討雲端服務在傳統製造業為公司經營所創造之效益。本研究從「傳統機械業遇到的挑戰與策略」、「個案F公司背景及營運現況(公司、產品、顧客)」、「雲端計算的應用」、「傳統機械業加上雲端應用後的效益」四個面向切入探討。 研究發現，傳統機械業在雲端應用的利益，不僅可以成為公司銷售策略、提升現有服務的品質更能以創新服務協助企業做節能診斷與建議，這樣不僅替客戶節省成本，並且增進顧客滿意度及黏著度。而另一個發現是透過雲端應用，可進一步作供應鏈管理，減少企業備料時間及降低庫存，使企業在激烈的競爭環境中，降低成本、增加毛利並創造企業長期的競爭優勢，同時為未來工業4.0之引進做準備。 關鍵字:雲端應用、傳統機械業、增加企業效益、 創新服務、增進顧客滿意度、 工業4.0. / Cloud applications have become prevalent in recent years. In particular, cloud computing is the operational model in key services for promoting big data analysis and open data interface. It also plays the vital roles in recent popular subjects, such as the internet of things, smart city, and industry 4.0. The objective of this study is to explore the current conditions of how cloud services are utilized in the traditional machine factories in Taiwan and to create benefits. With Company F as the case, this study examines how cloud applications are used to improve corporate benefits and customer satisfaction, as well as how strategies should be formulated for market differentiation to increase competitiveness, connect with current trends, and prepare for the prototype of industry 4.0. Through data collection, literary review, and interview with project implementation staff of the case, the study explores the benefits that cloud applications generate for the traditional manufacturing businesses. There are four focuses of investigation in this study—challenges encountered and strategies formulated by the traditional mechanical industry; case study of company F, including company background and the existing operation concerning the company, product and customers; applications of cloud computing; benefits of cloud applications on traditional mechanical industry. It is indicated in research findings that in the traditional mechanical industry, the benefits of cloud computing will not only become corporate sales strategy and improve existing service quality, but also provide diagnosis and recommendations on energy saving for corporations with innovative services. This will help clients cut costs, and improve customer satisfaction and adhesion. An additional finding is that cloud applications can further manage the supply chain, minimize lead time, and reduce inventory, which enable corporations to reduce costs, increase gross profits, and create long term corporate advantages in a competitive environment to prepare for the upcoming industry 4.0. Keywords: Cloud applications, traditional mechanical industry, improve corporate benefit, innovative service, increase customer satisfaction, industry 4.0.
