摘要

本研究基於可靠度理論中衰變觀點提出以貨架壽命之失效率，取代傳統損耗性商品之損耗率，換言之當損耗性商品之品質特性或功能隨時間退化時，當退化量超出某特定水準時即定義商品失效。例如生鮮肉品的損耗乃是因為微生物隨時間增生所致，而各項肉品微生物的標準衛生福利部皆有制定標準界限。另一方面，部分客戶因忠誠度於缺貨時願意等待，也有部分客戶當缺貨待補的時間過長，因而轉向其他公司購買，此時則會發生喪失銷售機會損失。因此，本研究針對損耗性商品，在允許缺貨的情形下，嘗試建構一個基於貨架壽命之經濟生產批量模式。

According to the degradation point of view in reliability theory, this study replaces the deteriorating rate with the failure rate of shelf life for deteriorating item. In other words, the quality characteristics or functions will deteriorate over time. When the amount of degradation exceeds a certain level, the failure of commodities is defined. For example, the loss of fresh meat is caused by the proliferation of microorganisms over time, and the Standard Health and Welfare Department of each meat microorganism has set standard boundaries. On the other hand, some customers are willing to wait when they are out of stock due to loyalty, and some customers turn to other companies to buy when they are out of stock for too long, at which time there will be a loss of sales opportunities. Therefore, this study aims at depleting commodities, and attempts to construct an economic production batch model based on shelf life under the condition of allowing stock-outs.
