考虑闭环供应链的差别定价问题,制造商回收废旧产品,并生产新产品和再制造产品,再制造率随机.采用Stackelberg博弈方法,研究集中决策和分散决策下相应产品的最优定价,给出供应链各成员的最优利润.结果表明:若制造商对产品延迟定价,则集中决策下回收价格高于分散决策,而销售价格均低于分散决策;当零售商的保守利润不低于一定值时,集中决策下总利润不低于分散决策,制造商可以采用改进的两部定价契约协调供应链.
Considering the problem of differential pricing of closed-loop supply chain, the manufacturer recycles discarded products, and produces new products and remanufactured products with random re-manufacturing rate. Using Stackelberg game method, the optimal pricing of corresponding products under centralized decision-making and decentralized decision-making is given. The optimal profit of each member in the supply chain is analyzed.The results show that if the manufacturer delays the pricing of the product, the recovery price under the centralized decision is higher than the decentralized decision, while the sales price is lower than the decentralized decision. When the retailer’s conservative profit is not lower than certain In the case of value, the total profit under centralized decision-making is not less than the decentralized decision-making, and the manufacturer can coordinate the supply chain with a modified two-part pricing contract.
