需求不确定且依赖于价格下,建立了全球供应链数量折扣与退货组合契约模型,得到了使全球供应链协调的组合契约参数。组合契约使供应链系统总利润接近于集中决策下供应链系统最大利润,而且供应商和销售商的利润均得到改善。在同样的组合契约下,销售商通过购买汇率期权,可以规避汇率变化的风险,提高自己的利润。
Under the uncertain demand and depending on the price, the global contract of supply chain quantity discount and return combination model was established, and the contractual parameters of the global supply chain coordination were obtained. The combined contract makes the total profit of the supply chain system close to the maximum profit of the supply chain system under the centralized decision, and the profits of the suppliers and distributors are improved. Under the same combination contract, sellers can avoid the risk of exchange rate changes and increase their profits through the purchase of exchange rate options.
