带有订单量和运输量折扣的供应链三方企业协调

Coordination of Three Parties in a Supply Chain with Order Quantity and Transportation Volume Discounts

考虑由供应商、运输服务提供商和购买商三者构成的供应链,市场需求是依赖于产品销售价格的随机变量,建立带有订单量和运输量双重折扣下供应链中三方企业的优化决策和协调模型。通过理论分析得到:提供订单量和运输量双重折扣可以促进供应链协调,同时提高供应商、运输服务提供商和购买商三方企业的利润。最后用算例验证了相关结论。

Considering a supply chain constituted by three enterprises---the supplier, transportation service pro- viders and the buyer under the condition that the market de- mand is a price-dependent random variable, this paper estab- lishes a tripartite optimization and coordination decision mod- el under the dual discount by order quantity and transporta- tion volume discount. Theoretically we prove that order quantity and traffic volume discount not only promote supply chain coordination, hut also improve the profits of the sup- plier, transportation service provider and the buyer. Finally, the related conclusions are proved by a numerical example.
