商业活动中供应商时常会给采购商短期的价格折扣，目的是使采购商进行临时的大量采购；供应商为了鼓励采购商订货，会针对采购规模给予其不同的延期支付期限；而当价格恢复到定常时，延期支付的期限则为供求双方事先规定的常值，采购商按照允许延期支付的EOQ模型订货。将延期支付基本EOQ模型中存在的门槛式延期支付规则（只有当采购量大于特定值才可以延期支付货款）应用并推广到这种临时采购中：延期支付期限是临时采购量的分段函数。由于采购商可以采取按低价追加订货或者放弃这个机会，基于这2种策略年度成本差异最大化，分析了采购商最优的追加订货批量如何确定的问题，拓宽了允许延期支付的EOQ模型应用范围。

Payment rule that payment is permitted only when order quantity is larger than a specific value was extended from past threshold-value style to the period of delay in payment that is a stepwise function of order quantity. The optimal temporary replenishment policy under this background was argued and analyzed. The result shows that the order size is determined by the on-hand inventory, capital interest, investment return interest, the price discount and the term of delay in payment.
