数量折扣契约对三阶层供应链的协调

Coordination in the Three-level Supply Chain by Revenue Sharing Contracts

研究了数量折扣契约对三阶层供应链的协调问题。首先针对供应链系统的全局协调,得出了契约参数以及最优订购量;引入利润分配系数,得出实现供应链完美协调的条件。通过数值实验得出如下结论:三阶层供应链的数量折扣契约下,制造商和零售商的批发价格不仅与各自的利润分配系数相关,而且随着订购量的变化而变化;实现全局协调的基础上,系统的完美协调取决于利润分配系数的取值。

It deals with the coordination with a three-level SC by the quantity discount contract. Firstly, the contract parameters and the optimal order quantity are determined with the channel coordination in the supply chain; then, the parameters of allocating profit are proposed for the perfect coordination; lastly, from the numerical experimentation, it concludes that ： the trade prices of the manufacturer and the retailer are related to the parameters of allocating profit, and they are related to the order quantity; on the basis of the channel coordination, the perfect coordination of the system is decided by the parameters of profit allocating.
