摘要

對於設備製造商、供應商及使用商等，整個供應鏈 (Supply Chain)架構來說，對於同供應鏈體系內備用零件的分享是必要的。若備用零件安全存貨設定過多，存貨持有成本金額將非常高，造成資金周轉率下降，容易引起財務問題；再者，若安全存貨過低則容易造成缺貨，造成生產線停頓，引起公司的損失。所以如何決定符合經濟考量的安全存貨是目前各類廠商所面臨之重要課題。對於一些產業設備都是昂貴之器材，零件失效大部份採取維修而非報廢，因此可修復性零件的多階層存貨系統的發展是必須的。
本研究延伸Sherbrooke所發展兩階層可維修存貨系統的備用件之存貨模式 (VARI-METRIC)，與VARI-METRIC模式不同點，在於本研究探討多面供給 (Multi Supply)之模式，其中包括平行供給(Parallel Supply)、回饋供給 (Feedback Supply)及交叉供給 (Cross Supply)，結果均較原始模式為佳。

For the equipment manufacturer, supplier and user in a supply chain system, it is beneficial for each partner for sharing spare part. If the stock level of a spare part is set too high, the holding cost will be huge, which will freeze the capital and thus might cause a financial problem. On the other hand, if the safety stock level is set too low, it may lead to a backorder and then cause a line-stop. Both will result in a business loss. Therefore, it is essential for determining an appropriate safety stock level for the manufacturer, supplier and user. It is very expensive for the equipment of some industries; when the equipment breaks down, it needs to repair rather than discard, hence developing an inventory model for the repairable spare parts is critical.
This research mainly extends Sherbrooke’s VARI-METRIC model, which deals with the allocation problem of multi-indenture repairable spare parts. The extension is to explore the multi-supply models, which include parallel supply, feedback supply, and cross supply. Their results are proved to be better than the original model.
