Effects of setup cost and random yield on the structure of optimal ordering policy

Abstract

In this article, we consider an economic order quantity (EOQ) model with multiple suppliers and random yield. We show that the structure of the optimal ordering policy is not only dependent on the structure of setup cost but also on the distributions of random yield. For some particular cases of random yield, the optimal order quantity from each supplier can be formulated as an explicit form.

在這篇文章中 ， 我們研究了一個具有多個供應商以及供貨不確定的EOQ模型。 我們證明了最優訂貨策略的結構不僅依賴於固定訂貨費用的結構 ， 還與隨機產出的分佈有關。 對於一些特定結構的隨機產出 ， 最優訂購量可以表示成明晰的運算式。
