摘要

近十年來，隨著社會的發展及科技的進步，在德國推出工業4.0的改革策略後，引起各國急起直追。由於在人力成本大幅增加的壓力下，代工廠的毛利率持續下降，使得台灣電子業如何選擇優質的供應鏈，並作好供應鏈管理已成為迫在眉睫的課題。
本研究以Ｌ公司為例（主要生產ATM、Printer、Scanner等成品機），因為其產品類別眾多，專門對客戶量身訂作，使得少量多樣化的產品，逐漸成為公司的生產常態。在此情況下，如何應對客人少量多樣的需求，並在競爭中取得優勝地位，就必須打破傳統的工作流程，從多方位尋求最佳之方法，但如此會大幅增加L公司的生產成本。由於Ｌ公司塑膠成型的產品佔整個材料成本的14%，且塑膠成型類之產品橫跨的領域甚廣，所以塑膠類供應鏈的優選及管理顯得十分重要。
本研究特以塑膠類產業為基礎，探討如何優選塑膠類廠商。本研究以Dickson (1966)提出之供應商評估指標為基礎，再透過專家的意見諮詢及前測問卷，建構出合適之評選架構，從而決定評分準則。且從Q(Quality)、D(Delivery)、C(Cost)、S(Service)、T(Technology) 、F(Finance)等六個方面進行評估，並使用信度及效度分析，以確認此問卷的可靠性。最後又以層次分析法(AHP)找出塑膠成型產業供應商評選之關鍵要素及其權重，並整理出塑膠成型產業供應商的評估表與量化指標。
彙總言之，本研究藉著提供塑膠成型產業供應商的評估與量化指標，來評量塑膠類供應商，希望能對塑膠成型產業的自動化、數位化及精實生產提供更佳的供應商、更低的成本及更穩定的品質，並且降低風險，以提升產業整體績效，達到共贏的目的。

Our the past decade, the information technology (IT) improved rapidly. Along with the Germany launched Industry 4.0, most of the developed and developing countries exerted themselves to catch up, causing the labor cost increased dramatically. Subsequently, the gross profit margin of the original equipment manufacturers declined greatly. Therefore, the supply chain is imminent to be managed properly in order to keep up with the development of the IT industry.
Adopting with the tailored-made strategy, L Company produced various types of products in order to meet different customers’ needs. Therefore, small amount and diversified productions has gradually become the normal production of L company in order to gain the advantages over competitors. Revising the traditional workflows to find solutions in different aspects, the L company’s cost of production increases dramatically. Of which, the cost of plastic material of L Company accounted for 14% of L company’s total material costs. Additionally, plastic products cover different areas, making the plastic supply chain management become very important.
This study employed the principal evaluation criterion method based on Dickson (1966), then this investigation used the expert interviewing method by using questionnaires to establish the proper selection structure. The scoring criteria was evaluated from the following six aspects: Q (Quality), D (Delivery), C (Cost), S (Service), T (Technology) and F (Finance). The reliability and validity analysis were then used to confirm the reliability of the questionnaire. This study then used the AHP method to find out the key criterion and the weighted point for each criteria. Finally, this investigation established an evaluation criterion standard for the plastic supply chain management.
In summary, this study provided the plastic molding industry’s automation, digitalization and production presion with better supplier, better cost, more stable quality and risk prevention in order to achieve the goal of win-win for the plastic molding industry.
