品牌专卖供应链的回购协调机制

为获得品牌专卖供应链的最优回购策略，在市场需求随机且与零售价格相关的前提下，建立了单一供应商和单一零售商组成的品牌专卖供应链的回购合同模型，并分析了基于线性价格折扣共担模式的回购合同．分析表明：在不以供应商的零利润为代价的基础上，存在多个批发价格和回购价格策略，使得供应链达到协调．此外，给出了协调时的最优合同参数．最后，通过算例进一步分析了该模型，得到了供应商利润、零售商利润以及供应链利润随合同参数变化的情况．

Research on Buy-Back Contract Mechanism of Brand Specialization Supply Chain

To obtain the optimal policy of a brand specialization supply chain with a supplier and a retailer,a buy-back policy model under a stochastic price-dependent demand was proposed,and a buy-back contract based on a linear price-discount sharing scheme was analyzed.The analysis shows that under a linear price-discount sharing scheme,there is much combination of wholesale price and buy-back price to coordinate the supply chain with the supplier's profit not being zero.In addition,the optimal contract parameters were given.Finally,a numerical example was given to deeply analyze the proposed model,and the profits of the supplier,the retailer and the supply chain as a function of the contract parameters were obtained.
