考虑一个供应链，其中零售商面临随机需求和供应商的订单，而供应商生产新产品并重新制造早期退货以满足订单。研究了三种分散情形下的订货量和制造量决策问题：（1）Stackelberg情形，即供应商在从零售商处获得订货量后再确定制造量;（2）Nash情形，即制造量和订货量同时确定;（3）退货信息不可获取的情况，即零售商不知道上游退货的分布信息。我们发现，在Stakelberg的情况下，订单和制造数量大于在不可访问的返回信息的情况下，供应商和零售商的利润也更高。相比之下，在纳什的情况下，产量和利润是最低的三种情况下，回报率是负相关的需求。集中系统也探讨了解决两步动态规划。计算结果显示系统参数的影响。
Consider a supply chain where the retailer faces a stochastic demand and orders from the supplier, while the supplier manufactures new products and also remanufactures early returns to meet the order. The order and manufacturing quantity decisions are studied under three decentralised cases: (1) the Stackelberg case, where the manufacturing quantity is determined by the supplier after realising the order quantity from the retailer; (2) the Nash case, where the manufacturing and order quantities are determined simultaneously; (3) the inaccessible return information case, where the retailer does not have the distribution information of upstream returns. We find that in the Stakelberg case the order and manufacturing quantities are larger than in the inaccessible return information case, and the profits for the supplier and retailer are also higher. In contrast, the quantities and profits in the Nash case are the lowest of the three cases when the returns are negatively correlated to the demand. The centralised system is also explored by solving a two-step dynamic program. Computational results are reported to show the effects of system parameters.
