摘要

面臨世界金融危機的衝擊，在各行各業不景氣的情況下，勢必要開源節流。「供應商管理存貨」(Vendor-Managed Inventory；VMI)，即是企業為了使生產和銷售目標順利達成而採用之一種有效的快速回應管理利器。
本研究考慮與實際狀況較為契合之供應鏈，即一家核心廠(例如，友達光電)與供應商之多階層(例如，三階層)VMI 系統，首先定義操作性變數之符號與提出基本假設，建構數學規劃模式，發展有效的求解方法，並進行實驗設計及求解效能分析。然而，本研究因為模式為NP-hard，故將針對小型問題使用數學規劃套裝軟體(LINGO)求最佳解，所求得的最佳解用來評估本研究基因演算法(GA)的求解效能。本研究期望以此存貨整合模式來改變過去供應鏈廠商單獨擬定決策
，轉以合作方式降低成本，維持供應鏈長期穩固合作關係，最終使得整體供應鏈更具競爭力。此外，本研究的實證結果與業界的觀點和實際情形非常吻合，印證本研究實證結果的正確性，希望藉由本研究案例提供未來研究導入VMI的廠商之重要參考依據。

In the face of the seriously economical crisis in today’s world, businesses in each industry should save costs and make an effort to find profitable opportunities in the situation where the global economics is in a state of deep depression.
The main purpose of this study is to construct an integrated VMI system. The VMI system (e.g., a three-level supply chain) includes a core TFT-LCD company (i.e., AU Optronics Corporation (AUO)) and its up-stream vendors. This study first defines the notations of operational variables and makes the basic assumptions. Then, an optimization package (e.g., LINGO) is used for the small-scale problems since it has been proven to be NP-hard. For the reason of difficultly obtaining an optimal solution, an effective heuristic method (i.e., genetic algorithm) is applied for saving the large-scale problems. In addition, an experiment and a computational efficiency analysis will be also conducted. It is hoped that our model can be used as an effective approach for VMI supply chain practitioners to cooperatively make their procurement, production, and delivery decisions, to maintain long-term stable partnerships, and to improve global competition. Most importantly, the results of this empirical study are shown to be correct since they are extremely similar to the view points of practitioners and real-world practices. We expect to provide practitioners who plan to install VMI systems in the future with the experience of the three case companies. Finally, the proposed mathematical programming model and the heuristic method are verified by this research for the aptness of practical use.
