摘　　要：传统的经济订货批量模型通常假设产品质量完好无损，但由于自然灾害、运输破损等不确定因素，因而实际情况非常少见，另外考虑了两层次延期支付，其中供货商提供给批发商延期支付期策略，同样批发商提供给零售商延期支付策略，建立了在商业信用条件下具有随机缺陷率产品的库存决策模型，然后得出批发商在不同情况下的最优订货周期、订购数量的简单判定方法．最后，通过算例说明了所得结论，并分析了参数变化对模型最优解的影响．The traditional inventory of the economic order quantity model assumes perfect items in an ordered lot. However, such conditions are rare in actual production environments due to many uncertain factors, including natural disasters, damages or breakages in transit. Additionally, two-level permissible delay in payments are considered, suppliers offering the wholesaler agrace period, wholesalers extending of a fixed credit period to downstream customers as well. Then, a inventory model for defective items is developed under two-level permissible delay in payments. Furthermore, a simple method is given for finding the optimal order policy. Finally, a numerical example is shown to illustrate the theoretical results of the proposed model, and influences of parameter changes on optimal ordering solutions are also analyzed.
