摘　　要：为了分析延迟返回可回收容器(RTIs)如何影响供应链的预期总成本,引用了利用RTIs完成从供应商到买方间成品装运的两阶段供应链模型。考虑了RTIs的返回时间是随机的,假定成品延迟配送会变质,讨论了模型的属性;通过分析返还提前期的三种情况,计算了供应链的预期成本,对模型求解并进行了案例研究。仿真结果表明:改变RTIs的返回批量,可以影响供应商RTIs缺货和成品变质的风险;大量减少延期交货订单是增加RTIs返还批量的有效措施。数值分析证明了该模型可为实际应用提供指导。In this paper, in order to analyze how the RTIs influenced the expected total cost of a supply chain, we referenced a two-stage supply chain model that used the RTIs in the finished product transportation between the supplier and the buyer, next considering that the return time of the RTIs was stochastic and assuming that the postponement in the distribution of the finished products would lead to quality deterioration, discussed the attributes of the model, and at the end, through analyzing three different lead time situations in a ease study, calculated the expected cost of the supply chain.
