Abstract
This paper investigates the optimal replenishment policy under conditions of permissible delay in payments within an economic production quantity (EPQ) framework. In 1985, Goyal assumed that:
1. | The unit selling price and the unit purchasing price are equal. | ||||
2. | The replenishment rate is infinite. | ||||
3. | At the end of the credit period, the account is settled. The retailer starts paying for higher interest charges on the items in stock and returns money of the remaining balance immediately when the items are sold. |
