摘要

近年來，國際資訊大廠皆要求台灣代工廠以低廉的價格、完整的服務體系、快速的生產與全球配送來符合其出貨上的需求，並以這幾點作為未來訂單釋出的審核標準。在這樣的市場趨勢下，使得資訊代工廠整體營運成本上升而利潤不斷的被壓縮減少；此時除了從經營行銷管理的層面上做變化外，應從整合內部資源來提升生產作業效能並藉此增加獲利。
在相關的研究中，除了實質生產機具或機械的調校與更新外，許多相關的研究皆以績效評估或生產線之人力平衡作為生產作業綜效提升的主要方法；其中在資料傳遞與整體系統結合上，部份過去研究除了應用了條碼讀取與變換載具外，並沒有提出較為整體化的方法，而在如何處理生產多樣化產品在組裝測試流程所發生的人為風險與相關問題，也沒有與資訊系統整合的相關研究。因此，本研究以資料傳遞與整體系統結合做為流程改造的主要目標，期望以精簡的設計與開發成本，對個案公司提出一個新的生產系統架構或方法，並藉此改變現有生產流程作業模式與效能，以帶動整體獲利並提供後續相關的應用。
研究中利用了網路開機功能與相關技術來簡化生產單元測試載具，而在資料傳遞上則利用監控程式經由TFTP通訊協定來傳送生產資訊至即時資訊系統，避免人為疏失；在測試單元的資料判斷利用了BIOS所提供的資料，使得多樣化產品的測試流程自動更換相對應之程式，並將所有系統都連接到生產專屬網路，經由網路資料庫提供生產所需之程式與資料的比對。
根據研究數據，可知作業流程網路化帶來快速的效率與彈性，並簡化人員操作，明顯的改善了測試程式的維護、實際生產作業行為以及即時資料的取得；從工作站良率的提高、錯誤率的降低，生產時間的縮短以及產能的增加中可以得知整體作業的效能提升。本研究藉由程式將網路技術連結於生產作業中，其中的方法與結果可提供相關產業做為開發系統的參考與比較。

All multinational information corporations have requested in recent years that Taiwan OEM manufacturers provide the lower prices products, intact service systems, rapid production and global dispatching. These features have been adopted as the standard for assessing the OEM order of future release. In the face of such market trends, factory operating costs face pressure to rise, threatening profits. Currently, besides change management method and marketing strategy should be to integrate internal resources to improve production efficiency and capability to make profitability.
Previous research, besides adjusting and updating the machine tool or mechanicals instrument, numerous investigations used the manpower balance or performance evaluation as the main method for promoting production line capability. In addition to applying the bar code or program carrier change in the research part, previous research did not submit the integrated method in the deliver data and whole system. Additionally, research was lacking on integrating information systems for transacting the artificial risk and related problems in the testing of the diversification product. Therefore, the process reformation in this investigation largely focuses on combining the whole system and data transfer methods. Expected to be accompanied by a low cost and simple design, provided a production system or method with a new structure. By changing the current production process operating mode and capabilities, the whole profit can be increased and the following application can be provided.
This investigation adopts the network boot function and related technologies to simplify the production unit test carrier. The supervision control program then is used to deliver the production data to SFIS via the TFTP protocol, thus preventing human error. The BIOS is used to provide information for data assessment and unit identification. The test process of diversification product is allowed to automatically change test program, and all systems are put on the exclusive production network, with the network database being used to provide the program and compare information.
After collecting and analyzing the related data, we find the network process provides the high efficiency and flexibilities, and also facilitates the operation. Test program maintenance, operational behavior, or the obtaining of real time production data all display an obvious improvement. The entire operating capability is promoted, as demonstrated by the increased pass rate, reduced fail reason, increased productivity and reduced production time. This research applied the programs to combine network technologies and production operations, and the results of applying these programs provide a reference or contrast for the related company in system development.
