跨國供應鏈決策輔助資訊系統─以TFT-LCD業為例

Abstract

供應鏈管理已成爲發展最快的商業智慧應用領域之一，而薄膜電晶體液晶顯示器(Thin Film Transistor-Liquid Crystal Display, TFT-LCD)是我國全力發展的高科技產業之一，是台灣繼半導體產業後，另一項產業新焦點。將跨國供應鏈管理結合到TFT-LCD產業，整合上中下游之供應鏈，將可提昇企業之核心競爭力。 本文提出一個跨國供應鏈之水平分工模式，以利用LINGO最佳化的模式語言求解出整個模式的最佳解，以達到利潤最大化為目標。系統模擬了不同環境變數及移轉計價下之產能分配和生產策略，並整合此模式與網際地理資料庫，設計出一供應鏈產銷管理系統，讓決策者及相關人員可以藉由易用的圖形界面清楚的查詢整個上中下游的情況，並用以做為決策之輔助。 本系統之貢獻在於結合考量階層式工單、移轉售價、稅額、需求變動等因素下，可用於支援變動環境下的跨國企業最佳化產能分配及生產、配銷決策，求取跨國企業的最大利潤。本系統之人機介面為以網際網路地理資訊系統(GIS)為架構，連結模式、資料與地圖，以期讓使用者進行供應鏈內各環節的資料查詢、更新及最佳化運籌，並可依決策者喜好自行訂定格式，匯出報表到Excel內，以利使用者可以依據需要，設定所需欄位，產出相關報表。 關鍵字：供應鏈、TFT-LCD、最佳化、地理資訊系統(GIS)

The supply chain management has become one of the fastest business intelligence application developments. TFT-LCD (the Thin Film Transistor-Liquid Crystal Display), on the other hand, is one of our core high-tech industries after the rising of the semi-conductors. By combining the international supply chain management with the TFT-LCD industry to integrate upper and downstream supply chains, the core competition of the enterprises can be elevated. This paper puts forward the mode of horizontal division of labor of the international supply chain and uses LINGO to find the best solution in order to achieve the maximum profit. By using various environmental variables and pricing transfer, the system simulates different output allocation and strategy. Furthermore, the model was integrated with the internet geographic database to design a production & sales management supply chain so that decision makers and related personnel can easily grasp the status of the upper and downstream by the user-friendly graphic interface in decision making process. Since the system incorporates factors such as hierarchical sheet of work, pricing transfer, taxes, requirement variance…etc., it can support the volatile international enterprises in finding the optimal output allocation, production and distribution solutions to maximize their profits. The system interface is structured around Internet geographic information system. It connects models, data and maps so that users can search, update and manipulate information in all sectors within the supply chain. Decision makers can also write up queries and export tables to Excel to edit columns according to their needs. Key words: supply chain, TFT-LCD, optimization, geographic information system
