摘要


本研究利用數學模式推導出製造商於不良品不完美重工生產系統下,且整合購買者存貨持有成本的兩個存貨模式之「最佳生產批量」與「最佳配送次數」。本研究假設製造商於正常生產過程會產生不良品,且不良品皆可重工,而不良品在重工修復期間亦有報廢品產生,至於配送方面,由於基本經濟生產批量模式是假設需求為連續配送的,但實務上並不符合實際情況,因為當製造商將產品配送至購買者時,經常使用定量批次的送貨方式。針對這些假設建立兩個存貨模式分別為:模式(一)為製造商於正常生產期間內生產足夠購買者在t1與t2時間內之需求量並先配送一次給購買者,接著在重工完成後再進行n次配送至購買者的存貨模式,稱為(n+1)次配送策略存貨模式;模式(二)為單一製造商於生產及重工後配送至多個購買者的多次配送策略存貨模式。接著分別建構模式(一)、(二)之數學模式且皆整合製造商與購買者存貨持有成本,使總成本最小化,並探討「最佳生產批量」與「最佳配送次數」之最佳化決策。最後提出數值例子作驗證,並對相關參數做敏感度分析與模式之比較,期望本研究之模式能夠因應實務上情況,提供業界作為實務應用與決策上之參考。

並列摘要


This study uses mathematical modelling to determine two model’s the optimal lot size for the finite production model with an imperfect rework process of defective items and frequency of delivery, and both of total costs contain buyer’s inventory holding cost. Due to traditional EPQ model assume that the demand for the shipment is continuous, but it is not realistic. Because when the manufacturer delivery products to the buyer, they often adopt a fixed quantity shipments. Hence this study assumes that each batch is dispatched to the buyer with a number of shipments, and considers defective items have failure ratio in rework, lead to production of scrap items during rework period. Two different inventory models are established by these assumptions respectively. They are: (1) EPQ model with (n+1) deliveries strategy. (2) EPQ model with multi-buyers. Both of long-run total costs include manufacturer and buyer of inventory costs, and our objective is to minimize two model’s long-run total costs. Finally, Numerical examples are provided to demonstrate its practical usage.
