针对n个制造商和2个零售商组成的供应链网络,假定不同制造商生产的品牌产品无差异、产品需求依赖于产品初始库存水平,并受到竞争产品库存和竞争零售商产品库存的影响,分别研究了各成员以自身利润最大化为目标进行分散式决策的带均衡约束的均衡模型、制造商主导的以品牌利润最大化为目标进行集中式决策的纳什均衡模型、以及零售商主导的以渠道利润最大化为目标进行集中式决策的纳什均衡模型,并给出了三种模式下的竞争均衡状态。结果表明,三种模式中分散式决策模式下的订购量最低,导致相应的品牌利润低于品牌利润最大化决策模式、相应的渠道利润低于渠道利润最大化模式。提出了可协调分散式供应链中零售商分别选择品牌利润最大化模式下的订购量和渠道利润最大化模式下的订购量的两种回购合同形式。数值算例表明了模型的合理性和协调合同的有效性。
For a supply chain network consisting of n manufacturers and two retailers, assuming that there is no difference between the brands produced by different manufacturers, the product demand depends on the initial inventory level of the product and is affected by the inventory of competing products and the inventory of competing retailers, The equilibrium models with equilibrium constraints and the manufacturer-led Nash equilibrium model with the goal of maximizing the brand profit are studied respectively, which are based on the individual profit maximization. The Nash equilibrium model led by the retailer Maximize the channel profit as the Nash equilibrium model of the goal of centralized decision-making, and give the competitive equilibrium under the three modes. The results show that the three models have the lowest subscriptions under the decentralized decision-making mode, resulting in that the corresponding brand profit is lower than the brand profit maximization decision-making model, and the corresponding channel profit is lower than the channel profit maximization model. Proposed two forms of repurchase contracts that can coordinate retailers in the decentralized supply chain to choose the order quantity under the mode of maximizing the brand profit and the order quantity under the channel profit maximization mode respectively. The numerical example shows the rationality of the model and the validity of the coordination contract.
