| dc.description.abstract | 近年來，整個代工產業面臨許多的挑戰及不確定性因素。客戶為避免出現斷炊煙之虞，紛紛要求代工廠須建構專屬料號，以確保其物料供給無虞。因此，導致代工廠庫存過高。隨著中美貿易戰及COVID-19疫情大流行而重擊全球經濟體系。這使代工廠面臨的問題更加複雜及艱鉅。除了庫存高居不下外，還須面對物料短缺以及營運利潤與業績下滑之問題。
本研究對象A公司是國內EMS代工製造商，針對該公司目前所面臨的問題，經初步調查分析後，發現物料頻繁短缺及一物多號是造成庫存過高的主要原因。而受限系統分權資料庫管理問題，造成廠對廠的庫存無法有效管理及調度。因此，本研究將針對此問題提出一個有效的改造計劃來解決物料調度以降低庫存及成本。
本個案研究主要針對A公司全球物料管理進行改造計劃評估。首先，針對物料編號結構進行改造，利用主次料號二層結構及建構物料關鏈性來滿足客戶的要求。其次，是在新料號申請時，系統將進行卡關機制並配合一料一號之原則。最後將針對廠對廠的物料調度機制，透由系統設定進行庫存移轉以落實精實物料運用。
經由改造計劃評估分析後發現，此提案除了可有效的降低庫存外，同時，亦減少物料短缺問題。而物料精實運用使庫存的降低成本也同時帶來更高的利潤。 | zh_TW |
| dc.description.abstract | In recent years, the EMS industry at large has been facing many uncertainties and challenges. In order to avoid the risk supply chain disruption, business buyers have requested electronic manufacturing services (EMS) to adopt material numbers for their exclusive use, resulting in high inventory levels for the EMS. The U.S.-China trade war and the COVID-19 pandemic have severely impacted the global economic system. This further complicates the problems faced by the EMS, denting operating performance and profits.
This study attempts to investigate the problem facing Company A, a domestic EMS manufacturer. Initial investigation determines that multiple numbers for a single material item happened to be the root cause of high inventory, and frequent shortage. This is coupled with information silos and lack of effective inter-factory transfer of materials. A plan is proposed to tackle the problem.
The proposal includes the following actions. First, a two-tier part number structure is proposed to create unique, exclusive number for the customers, and an associated cross referencing mechanism is also designed to meet the requirements. Second, the process of registering new part numbers, and controlling the storage are designed to enforce the rule of “each part must receive only one part-number.” Third, a cross factory transfer mechanism for material is also proposed.
Analysis found that the proposal could result in lower inventory levels, and reduced material shortages at the same time. This translates into lower inventory cost and higher profit margin. | en_US |
