中文摘要 本研究針對易腐性產品建立不完美品質之經濟訂購量模式,本研究以經濟訂購量模式為基礎,加入易腐性產品之存貨模式,將瑕疵物品以分批的方式進行處理,降低存貨成本,並求解出最佳經濟訂購量與最佳分批處理次數。本研究建構的模式共有三種,分別是易腐性產品之經濟訂購量、瑕疵品分批處理之模式以及易腐性產品採瑕疵品分批處理之模式,此三種模式的適用性不僅侷限於易腐性或不完美產品,只需要將參數設定調整至適合產品的範圍即可套用本模式以進行求解。
從數值範例可以知道各個模式之間的關聯性,以及應用的方式,再由敏感度分析可以了解到各個參數與決策變數的相關性及其強弱程度,比較特別的是存貨成本與瑕疵品分批處理數沒有相關性,這與一般的想法有所不同,通常認為存貨成本越大勢必要將瑕疵品分批處理數提高才能降低存貨成本,然而存貨成本又會影響到經濟訂購量,存貨成本大會使得經濟訂購量下降,而訂購量下降便會使得瑕疵品分批處理數降低,也就是在一連串的關係下,存貨成本與瑕疵品分批處理數是沒有關聯性。
雖然存貨成本與瑕疵品分批處理數沒有相關性,但是在探討利潤的差異時,存貨成本的大小會決定瑕疵品分批處理的重要性,亦即當存貨成本越大,進行瑕疵品分批處理越重要。
英文摘要 This paper considers EOQ (Economic Order Quantity, EOQ) models for perishable product with imperfect quality where cumulative holding cost is a nonlinear function of time. Since handling the imperfect products in batches could reduce the holding cost and have better profits, this paper develops three models, including EOQ of perishable products, handling imperfect products in batches and handling the perishable products with imperfect quality in batches, and finds the optimal ordering quantity and the number of batches to handle the imperfect products. This paper illustrates the application of developed models by numerical examples and sensitivity analysis.
As the result, we find that holding cost do not have the correlation with the numbers of batches to handle the imperfect products. In general, we thought that holding cost can be reduced by larger number of batches. But on another way, we have to notice that larger holding cost can decrease the order quantity. When the ordering quantity decreased, the number of batches would be lower. So, we can explain that the holding cost do not have the correlation with the numbers of batches in this paper.
Comparing whether to handle the imperfect products in batches or not, higher holding cost would affect more on the difference of profit. It means that the higher holding cost is, the more important to handle the imperfect products in batches.
