具有风险决策者的供应链协调研究

Research on supply chain coordination with risk-averse bias

通过假定制造商为风险中性,零售商为风险厌恶,建立了具有风险厌恶偏好的退货政策模型,并在此模型的基础上,分析了制造商如何通过实施退货政策来实现供应链协作,确保整个供应链最优。证明了零售商的风险厌恶偏好在一定范围内,退货政策可以实现供应链协作,但零售商的风险厌恶偏好高于或低于一临界值时,退货政策将无法实现供应链协作。此时,在退货政策下引入批发价格契约,证明了在退货政策下引入批发价格政策能够协调供应链,并确定了相关参数。

Supposing a supply chain composed of a risk-neutral manufacturer and a risk-averse retailer, the return policy with a risk-averse-lies retailer is modeled. Based on the models and the whole supply chain optimization, the strategy of provid- ing the return policy to coordinate the supply chain is analyzed. It is proved that when the retailer＇s risk aversion is in a certain range, the return policy can achieve supply chain coordination, but when the retailer＇s risk aversion is beyond a critical value, the ruturn policy will not be able to achieve supply chain coordination. At this point, we intmduct the wholesale price contract under the return policy, and it is proofed that the supply chain can be coordinated. Finally, the relevant parameters are deter- mined.
