Economic Order Quantity and Quantity Discounts Under Date-terms Supplier Credit: A discounted Cash Flow Approach
研究了在供应商提供日期条款信用（即采购、订货和持有成本支付日期不同）时，如何用折现现金流方法确定全单位折扣和增量折扣下的最优订货量，替代了传统忽略现金流时间差异的周期成本最小化方法。
This paper examines economic order quantity and optimal order quantity under both all-units and incremental-quantity discounts when purchase cost, order cost, and carrying cost are all incurred on date-terms supplier credit. Payment dates for the three cost components need not be the same. The traditionally-used periodic-cost minimization methodology which is insensitive to differences in the timing of various within-period cash flows is replaced with a discounted cash flow methodology. Differences in the characteristics of day-terms and date-terms solutions to the quantity discount case are high-lighted.
