回购契约下具有损失厌恶型零售商的供应链协调问题

研究在不确定需求下由单个风险中性的供应商与单个损失厌恶的零售商组成的两级供应链问题。不同于传统的线性损失厌恶效用函数，应用展望理论在回购契约中研究效用函数为分段非线性函数时的零售商的决策行为，以及整个供应链的协调问题。研究表明，损失厌恶的零售商的最优订购量随其损失厌恶程度的增大而减少，随回购价格的增大而增加，且对整个供应链来说存在唯一的一个回购价格，能够使整个供应链达到协调。

Coordination of a Supply Chain with Loss-averse Retailer under Buyback Contract

A one-manufacture and retailer supply chain facing uncertain demand was studied. Different from the traditional piecewise linear loss-averse utility function, this paper takes the viewpoint of the prospect theory and assumes that the retailer＇s utility function is piecewise-nonlinear. The decision-making behaviour of retailer and the coordination of whole supply chain in buy-back contract were studied. It is found that the loss-aversion retailer＇s optimal order quantity decreases as the degree of loss-aversion increases and the greater the buyback credit the more the optimal order quantity of retailer. Furthermore, There exists a unique buyback credit can coordinate the whole supply chain.
