基于收益共享契约的网购供应链库存运输联合优化模型研究

Study on Joint Inventory and Transportation Optimization Model of Online Shopping Supply Chains Based on Revenue Sharing Contract

依次构建了网店和物流服务商单独决策时的利润分配模型、库存运输联合优化时的利润分配模型以及基于收益共享契约的库存运输联合优化模型,研究发现,在库存运输联合优化模型中,供应链整体利润和物流服务商的利润较单独决策模型时都得到了增加,而网店利润减少了;在基于收益共享契约的库存运输联合优化模型中,当收益共享契约参数取值在一定范围内时,供应链整体、网店和物流服务商的利润都得到了增加;契约参数在允许的范围内变动时,网店和物流服务商的利润分配也随之变动。最后通过算例验证了模型的可行性。

In this paper, we successively established the profit distribution model for the online shops and logistics service providers who made separate decisions, the profit distribution model for the online shops and logistics service providers who participated in joint inventory and transportation optimization as well as the joint inventory and transportation optimization model based on the revenue sharing contract, found that in the joint optimization model, the overall profit of the supply chain and the profit of the logistics service provider were both higher than that of the separate decision-making model, but the profit of the online shops was fewer; in the revenue sharing contract based optimization model, when the value of the parameters of the contract were within a certain range, the profit of the supply chain in general, the online shops and the logistics service providers were all increased. At the end, through a numerical example, we analyzed the feasibility of the models established.
