【摘要】：研究需求随机且依赖于库存量情况下,n个零售商销售2个制造商生产的无差异品牌产品的库存竞争问题。利用均衡分析方法分别建立了2-n型供应链中最大化各成员利润的EPEC模型、最大化各品牌利润的Nash均衡模型,以及最大化各渠道利润的Nash均衡模型,并进行了模型求解。结果表明,成员利润最大化下的订货量最低,导致相应的品牌利润和渠道利润分别低于品牌利润最大化情况和渠道利润最大化情况。提出了两种回购合同形式,使得零售商在两种合同下最大化自身利润的订货量决策分别与品牌利润最大化和渠道利润最大化的订购量一致。最后,对模型的合理性和协调合同的有效性进行了数值仿真分析。
[Abstract]:In this paper, the problem of inventory competition in which n retailers sell undifferentiated brand products produced by 2 manufacturers is studied under the condition of random demand and dependent on inventory stock. The EPEC model of maximizing the profit of each member, the Nash equilibrium model of maximizing the profit of each brand and the Nash equilibrium model of maximizing the profit of each channel in 2-n supply chain are established by using the equilibrium analysis method, and the model is solved. The results show that the order volume is the lowest when the member profit is maximized, which leads to the corresponding brand profit and channel profit being lower than the brand profit maximization and the channel profit maximization respectively. Two types of repurchase contracts are proposed, which make the decision of order quantity of the retailer to maximize their profit under the two contracts consistent with the order quantity of the maximization of brand profit and channel profit, respectively. Finally, the rationality of the model and the effectiveness of the coordination contract are analyzed numerically.
