针对零配件供应商产量不确定对制造商后期装配生产的影响,本文在一个“两供应商-单制造商”构成的二阶装配式供应链系统中,构建了分散决策下的供应链成员利润模型和集中决策下的供应链总利润模型.并研究了不同类型缺货惩罚的设定对供应商产量决策的影响,从提高供应商协同积极性的角度提出了一种惩罚契约模式,使供应商主动选择集中决策下的供应链最佳产量.数值分析表明该模式可以调节供应链总利润在供应商与制造商之间的分配,这有利于促进供应链成员之间关系的和谐.
In view of the influence of uncertain output of spare parts suppliers on the manufacturer’s final assembly production, this paper constructs the second-order assembly-type supply chain system consisting of "two suppliers - single manufacturer Member profit model and total supply chain profit model under centralized decision, and studies the influence of different types of out-of-stock penalty setting on supplier output decision-making, proposes a punitive contract mode from the viewpoint of improving the cooperation enthusiasm of suppliers, The supplier proactively chooses the optimal output of the supply chain under the centralized decision.The numerical analysis shows that this model can adjust the distribution of the total profit of the supply chain between the supplier and the manufacturer and this can promote the harmony of the relationship among the members of the supply chain.
