基于订货量的延期付款条件下三阶段经济订货模型

EOQ Model under Three Levels of Order-size-dependent Delay in Payments

已有考虑延期付款的EOQ订货模型多为两阶段模型,一般只考虑单个供应商、单个零售商的情况。然而,实际上,零售商为刺激需求而给顾客提供延期付款计划却是常见的商业行为,为此,假定供应商给予零售商基于采购数量的延期支付、零售商给予顾客固定期限延期支付,将考虑延期支付的EOQ订货模型拓展为供应商、零售商、顾客三阶段模型。算例结果表明,基于订货量的延期付款对零售商经济订货批量有较大的影响,并呈现出一定的规律性。

Much of existing EOQ models under delay in payments are two-level EOQ model, considering only one supplier and one retail. While in reality, it is quite common that retailer will offer customer a delay period to increase sales income. This paper develops EOQ models under delay in payments to three-level EOQ model, assumed that supplier offers retailer order-size-dependent delay in payments and retailer also gives customer a fixed period of delay in payments.
