针对单个制造商和单个销售商组成的多周期单产品两级供应链协调问题,建立了期权与数量柔性契约相结合的决策模型;需求的不确定性通过有限的情境描述,采用逐步对冲算法对基于情境的随机规划模型进行求解,给出了销售商最优的期权购买量和初始订货量以及制造商最优的原材料采购量和产品生产量;最后通过数值仿真实验验证了所提出模型的有效性. Aiming at the problem of two-level supply chain coordination of single-cycle and single-cycle products, a decision-making model combining option and quantity flexible contract is established. The demand uncertainty is described by a limited context and a gradual hedging algorithm Based on the scenario-based stochastic programming model, the optimal sellers purchase quantity and initial order quantity, and the manufacturer’s optimal purchasing volume of raw materials and products are given. Finally, the numerical simulation results show that the proposed model is effective Sex.
