近來國際品牌筆記型電腦的電池發生了過熱現象而招回更換的事件發生後,國際廠商對於台灣代工廠商下訂單時對於產品的原料來源及生產的相關製程的數據要提供外,進一步希望能即時的看到原料供應商的生產數量及品質檢驗結果,可以對於品質超出規範的原料做控管外,進一部也會求代工廠商對相同時間生產的原料做嚴格的進料檢驗或拒收等動作。 本研究以代工廠商的角色設計一套SPC系統串連眾多原料供應商與客戶間的橋樑,以數據驅動管制圖的呈現,並加上廠商要求的管制規則去計算各生產數據是否超出管制的界限以及時的通知廠商及客戶,符合客戶所需外,也讓三者之間的資訊及溝通更流暢,減少因為原料的不良導致後續品牌形象的損害及回收處理費用的產生。本研究透過SPC軟體的實作來實現虛擬工廠的概念,讓客戶能掌握到原料、組裝廠商的生產資料,可以減少現場抽驗的稽核動作及明瞭訂單生產狀況。
In order to control supplier's production quality, this research designs a SPC system to establish a bridge between suppliers, customers, and manufacturers. By collecting production data from suppliers, the system could present a real time statistics data and data charting of investigating process capability. According to the capability statistics, customers could communicate with manufactures and suppliers in real time. Suppliers and manufactures can monitor the production quality so as to reduce the fail rate of production as well as understand the status of production line.
