为了体现风险中性市场中自由竞争在易逝品供应链模型中的协调作用,建立了与不同零售商的零售价格相关的随机需求下具有退货机制的单一制造商和两零售商的二级供应链模型。分析表明:在传统二级供应链中,无竞争模型的利润明显小于零售商自由竞争的供应链模型,并且通过特殊的线性模型给出了易逝品供应链协调下的最优零售价和最优订货量,分析了各种参数变动对最优零售价、最优订货量以及供应链各成员利润的影响。
In order to reflect the coordinating role of free competition in the perishable supply chain model in risk-neutral markets, a secondary supplier of single manufacturer and two retailers with a return mechanism with random demand related to the retail prices of different retailers is established Chain model. The analysis shows that in the traditional two-level supply chain, the profit of the uncontested model is obviously smaller than the supply chain model of retailers’ free competition, and the optimal retail price under the coordination of perishable product supply chain is given through a special linear model The order quantity is analyzed, and the influence of various parameter changes on the optimal retail price, the optimal order quantity and the profit of each member in the supply chain is analyzed.
