摘要

由於資訊科技的進步及競爭市場全球化的趨勢，供應鏈存貨管理逐漸發展成一重要的領域。供應鏈存貨管理的基本精神是有效整合同一條鏈上所有的合作夥伴，使得整體供應鏈利潤最大化或是成本最小化。因此，如何決定供應鏈上合作夥伴之間的庫存策略，達到整體供應鏈最大績效，是值得探討並研究的課題。

本論文討論單一製造商與單一零售商的二階整合存貨系統，在可控制前置時間及零售商允許缺貨情況下，建立連續性檢查存貨模型，探討降低訂購成本與考慮產品品質對最適生產/訂購策略的影響。文中建構八個不同的存貨模型，共同的決策變數有訂購數量、請購點、前置時間和運送次數。首先，第一章說明研究動機與目的及相關文獻探討。第二章在生產/訂購批量中沒有不良品，零售商允許缺貨的情況下，建構可控制前置時間的整合存貨模型。第三章在前置時間的縮減與訂購數量有關，零售商允許缺貨的情況下，加入投資資金以降低訂購成本的考量，建立整合存貨模型。第四章在零售商訂購數量中含有不良品，並且允許缺貨的情況下，建立採用全部檢查策略的整合存貨模型。第五章在製造商投資資金改進不完善的生產製程，且零售商允許缺貨的情況下，建立整合存貨模型。本論文對所建構的數學模型，均建立演算法，並以數值範例說明求解程序，找出最適的訂購、生產及運送策略。同時，本論文亦分析各模型中參數值的變動對最適解所造成的影響，提供給管理者做決策之重要參考依據。最後，在第六章裡將上述各章所得的結論做一總結，並說明未來的研究方向。

Due to the improvement of information technology and the tendency of global market competition, inventory management in supply chain has become an important research issue. The basic tenet of supply chain management is to integrate business partners in a chain efficiently so as to maximize total profits or minimize total costs. Therefore, it is important to determine an efficient inventory strategy within supply chain partners to achieve the best performance of the chain.

This thesis proposes some single-vendor single-buyer integrated inventory models with continuous review. It is assumed that shortages are allowed and lead time is controllable. Eight two-echelon inventory models are established in this thesis, and the common decision variables here are ordering quantity, reorder point, lead time and the number of lots delivered from vendor to buyer. Chapter 1 covers the motivation and objectives of this thesis. In this chapter, literature review about related research papers is also included. Chapter 2 introduces integrated inventory models with shortages in controllable lead time. Chapter 3 assumes that lead time reduction cost depends on the lead time length to be reduced and the ordering lot size. This chapter introduces integrated inventory models with controllable lead time and ordering cost reduction. Chapter 4 provides integrated inventory models for defective items in buyer’s arrival order lot with shortages and full-lot inspection policy. Chapter 5 deals with the impact of investing in quality improvement and lead time reduction on the integrated inventory models with shortages. For each integrated inventory model, this thesis established algorithm to determine the optimal strategy and numerical examples are provided to show the solution procedure. Also, sensitivity analysis is conducted for the parameters of the models. Finally, chapter 6 provides the conclusions of this thesis and some future research topics.
