Abstract: To study supply chain coordination problems under inventory financing, and verify the coordination effect of the buy-back contract, a centralized supply Chain is constructed. Using the optimization theory and methods, a supply chain model without any contracts, a supply chain model with a traditional buy-back contract and a supply chain model with a buy-back contract considering the target quantity are constructed. The coordination results are proved through the comparison among supply chain profits in the three cases. Perfect coordination conditions are given by analyzing the profits under different decision patterns. Finally, study results are illustrated by a numerical example.

Key words: supply chain, inventory financing, loordination, buy-back contract

摘要： 为分析供应链金融中存货质押融资模式下的供应链协调问题,验证回购契约对该供应链的协调效果,文章在分析集中式供应链的基础上,利用优化理论和方法构建了无契约协调时供应链的基准模型、传统回购契约下的供应链模型以及考虑目标订购量的回购契约下的供应链模型,通过三种情况下供应链及供应链成员利润的对比,分析说明回购契约的协调效果。通过不同决策模式下供应链及供应链成员利润分析,给出回购契约完全协调该存货质押融资供应链的条件,最后通过仿真进一步验证了协调效果。
