研究了在需求不确定及供应可能发生中断的情况下,同时考虑订货过剩风险与短缺风险,构建了双重采购条件下期权合同与回购合同协调合作的三级供应链模型,通过设定相应参数达到供应链协调。供应链协调时的最优订货量及整体利润大于分散式模型;供应中断风险不影响价低不稳定制造商的订货量,而价高稳定制造商的订货量随风险增加而增加。
In the case of uncertainty of demand and interruption of supply, considering the risk of excess ordering and the risk of shortage, the author constructs a three-level supply chain model of coordination and cooperation between option contract and repurchase contract under dual procurement conditions. By setting the corresponding parameters Achieve supply chain coordination. The optimal order quantity and overall profit in supply chain coordination are larger than the decentralized model. The risk of supply interruption does not affect the order quantity of unstable manufacturers with low prices, while the order quantity of stable high price manufacturers increases with the increase of risks.
