不導電鍍膜生產系統多品質特性檢驗站設置問題之研究

不導電鍍膜(Non-conductive Vacuum Metallization, NCVM)製程可應用於各種塑料材料，如PC、PC+ABS、ABS、PMMA、NYLON、工程塑料等，它更符合製作工藝的綠色環保要求，是無鉻（Non-Chrome）電鍍製品的替代技術，適用於所有需要表面處理的塑料類產品，特别適用於有訊號收發的3C 產品，尤其是在天線蓋附近區域，如行動電話、PDA、智慧型手機、GPS 衛星導航、藍芽耳機等。NCVM 外觀有金屬質感且不影響到無線通訊傳输之效果，因此許多手機品牌大廠將NCVM 技術運用在自家產出的智慧型手機外殼及按鍵中都有運用NCVM 技術以增加手機整體的美觀性，以增加手機的賣相，進而促使銷售量增加。本研究藉由所建構出之NCVM序列式生產系統的數學模式，求取利潤最大之最佳檢驗站設置方案，其中成本項目包含加工成本、檢驗成本、報廢成本、外部損失成本等，研究結果顯示最佳檢驗站設置方案並非全檢方案。本研究相信能提供給NCVM生產系統決策者更有效的檢驗資源規劃與檢驗站設置時之參考。

Non-conductive vacuum metallization (NCVM) process can be applied to various plastic materials, such as PC, PC+ABS, ABS, PMMA, NYLON, engineering plastics, etc. It is not only compliant with the environmental protection requirements but also an alternative technology of plating products, which can be applied to all plastic products that surface treatment is needed, especially to the signal sending/receiving products, particularly in the vicinity of the antenna covering areas such as mobile phone, PDA, smart phone, GPS satellite navigation, Bluetooth headsets, etc. NCVM has a metallic appearance and does not affect the wireless transmission so many mobile phone manufacturers use the NCVM technology in the shells and keypads of their own brand smart-phone to improve the overall appearance of the phone, in order to attract the consumer to promote the sales. This study is based on the mathematical model of the NCVM serial production system to find the best inspection allocation at the highest profit. The cost considered in the mathematical model includes process cost, inspection cost, scrape cost and external failure cost. The study has shown that the best inspection allocation is not necessary in total inspections. We believe that this study can serve as a reference for the decision makers of NCVM serial production systems effectively in the planning inspection resources and assessing the performance of inspection allocation.
