物流服务数量折扣与回购分包合同模型

Logistics Service Quantity Discount—Return Subcontract model

回购合同是第三方物流提供者与分包商合作机制的组成部分。与Berglund M关于从第三方物流提供者的角度出发提出的回购合同的思路相比,本文从激发分包商合作意愿的角度,提出了一个三阶段物流服务数量折扣与回购分包合同模型:回购模型、子博弈精炼纳什均衡模型及数量折扣与回购模型,并逐步与初始阶段模型相比较,结合具体数据验证了该模型是可以达到帕累托最优的。

This paper corlsiders the problem of coordination mechanism between third - party logistics supplier and subcontractor. Compared with the return contract opinion which focuses on optimization from the third - party logistics supplier＇ s, s perspective proposed by Berglund M, a three - stage logistics service quantity discount-return subcontract model is proposed from the subcontractor＇s perspective which is composed by return contract models, subgame Nash- perfect equilibrium model and quantity discount-return model. Compared with the initial model gradually, it is demonstrated that Pareto efficiency can be attained in the model and the scenarios are illustrated through a numerical examole.
