在傳統探討的最佳訂購量或生產量,大多數都是針對製造商或是針對零售商去考慮,而在現今社會,提升競爭力,要提升競爭力除了降低成本外,還可以透過合作夥伴的關係,互相協商。而在現實中,生產不良品是非常常見,不良品可特過加工使其變成良品。 另外,產品的生命週期也慢慢必須納入考量,科技進步,產品可能上市不到三個月或一年,就有其他新產品取而代之,傳統的預測方法沒有考慮到這類商品的特點,可能與現實不符。 因此,本研究結合上述的問題,加入考量不良率、報廢率、重工及金錢時間價值,重新提出一個整合兩階供應鏈的存貨模式,已決定最佳生產量、生產週期及訂購數量、訂購次數,使得聯合總成本最小 關鍵詞 : 時間價值、重工、存貨模式。
Traditional Economic Order Quantity and Economic Production Quantity models is only consider a retailer or only consider a manufacturer. In a competitive society, increasing the competitiveness of a business is not only reducing cost, but also enhancing partnership with others. In reality, the imperfect product are produced very common, rework process is necessary to convert those defectives into finished goods. In addition, must to be consider product’s life cycle, when the new product has enter to market three months or one year, that other new product can to replace it, Traditional forecast do not consider product’s life cycle. Therefore, this study integrates the above questions including defect rate, scrap rate, rework and time-value. An integrated two-echelon inventory model to decide the best production quantity, product frequency, order quantity and order frequency. As a result, the total cost can be minimized.
