具有损失厌恶偏好零售商的供应链弹性数量契约

研究由风险中性供应商和具有损失厌恶偏好零售商组成的供应链在弹性数量契约条件下的协调问题.揭示了契约参数和零售商损失厌恶特性对零售商最优订货量的影响,发现调整弹性度这一契约参数可使供应链得到协调;同时,当弹性度满足一定条件时,调整批发价格也可实现供应链协调.最后通过数值分析,验证了弹性数量契约在协调供应链中的有效性,并探讨了其中原因.

Research on supply chain quantity flexibility contract with a loss-averse preference retailer

Under quantity flexibility contract,the coordination of supply chain with a risk-neutral supplier and a loss-averse retailer is discussed.The impact of contract parameter and retailer’s loss-averse characteristic on the optimal quantity is revealed.It is found that the supply chain can achieve coordination with regulating the degree of flexibility.When the degree of flexibility satisfies certain condition,changing wholesale price can also coordinate the supply chain.Finally,numerical analysis verifies the effectiveness of quantity flexibility contract in supply chain coordination,and the reason is discussed.
