损失厌恶型零售商参与的供应链商业信用与收益共享协同研究

Coordinated Study on Trade Credit and Revenue Sharing in the Supply Chain Involved by Loss Averse Retailers

在考虑零售商风险偏好的情况下,运用前景理论分别构建传统供应链模型、商业信用模型和商业信用-收益共享协同模型,研究每种模型的一体化决策和分散决策下零售商最优决策及供应链协调问题,探讨商业信用和损失厌恶等参数对零售商最优订货决策的影响。研究表明,零售商订货量与商业信用期限和收益共享系数成正比,而与损失厌恶系数和批发价格成反比。在商业信用模型基础上,引入收益共享机制,建立商业信用-收益共享协同模型,最终供应链成员均实现帕累托最优。最后通过数值仿真,验证了商业信用-收益共享协同模型在面向损失厌恶型零售商时的有效性。

Considering retailers＇ risk preference, this study employs prospect theory to construct the traditional supply chain model, the trade credit model and the coordination model of trade credit and revenue sharing, and explores the retailers~ optimal decision and coordinated issues of supply chain under the integral decision making and decentralized decision making of each model. Further- more, the effects of parameters such as trade credit and loss aversion on retailers optimal order deci- sion are investigated. The findings show that retailer＇s order quantity is directly proportional to trade credit term and revenue sharing coefficient while order quantity is inversely proportional to loss aver- sion coefficient and wholesale price. The trade credit model is an improvement of the traditional sup- ply chain model and it increases retailers~ order quantity. However, it can＇t realize supply chain coor- dination. On this basis, we introduce revenue sharing mechanism, and thus, the coordination model of trade credit and revenue sharing is established. Finally, supply chain members can achieve Pareto optimality. The objective functions of supply chain members in the three types of models are analyzed and compared through numerical emulation. And this study has discussed parameters setting in the model and examined the effectiveness of the coordination model of trade credit and revenue sharing when it targets at loss aversion retailers.
