Economic Inventory/Transport Lot, Sizing with Quantity and Freight Rate Discounts
研究了在确定性经济订货批量系统中，如何将供应商的数量折扣和承运商的运费折扣纳入订货批量决策，并针对四种折扣组合推导出最优批量算法。
ABSTRACT Discounts are a primary marketing mechanism for inducing customers to increase the size of their purchases. Quantity discounts from suppliers and freight discounts from shippers are commonly encountered by organizations. This paper structures quantity and freight discounts into the order size decision in a deterministic economic order quantity system. Optimum lot‐sizing algorithms are derived for the dual discount situations of all‐units or incremental quantity discounts and all‐weight or incremental freight discounts.
