基于价格折扣的物流服务供应链协调模型研究

Study of Coordination Model of Logistics Service Supply Chain under Demand Uncertainty

在一个物流服务集成商与一个物流服务提供商及一个客户构成的物流服务供应链中,文章建立了各个利益主体的利润模型及物流服务供应链的整体利润模型,并分别求解了其最优解,通过对模型的分析和求解,得出各个利益主体与整体供应链的最优解存在矛盾。为了协调这个利益矛盾,提出了利用价格折扣契约来对物流服务供应链进行协调,并计算得出价格折扣系数的取值范围,最后给出了算例以证明这种契约对物流服务供应链的协调具有有效性。

Based on a logistics service supply chain combined by one integrator, one supplier and one customer, profit models of the integrator, supplier and overall logistics service supply chain were established, and the optimal solutions were calculated individually. And according to analyzing these models, a solid conclusion can be deduced that the profits of integrator and supplier are both inconsistent with that of the overall supply chain. In order to coordinate the contradiction existing in logistics service supply chain, a contracting ap- proach was proposed. Also the price discount coefficient＇s val- ue range was given out. Finally, a numerical analysis about logistics service supply chain combined with one integrator and one supplier was given to prove the effective of the solution.
