供应链网络均衡中的利润协调问题

Effective profit allocation in supply chain equilibrium

为了解决在通常的买方和卖方市场中,供应链处于均衡状态时,供应商与零售商的利润固定,其链内的利润分配无法达到双方均满意的问题,建立了有随机需求的供应链网络均衡模型,并且将回收合约引入该模型中.利用回收合约的协调作用,使得供应链在制造商和零售商都满意的利润分配下达到均衡状态.通过算例分析得出了回收契约能够很好地解决在买方或卖方市场条件下供应链处于均衡状态时的利润分配.为供应链均衡提供了一种新的思路.

In the usual market, when the supply chain attains equilibrium, profits for the supplier and the retailer are fixed, and the profit allocation doesnt satisfy one of the parties. A buy back contract was introduced to an equilibrium model of a supply chain network with stochastic demand. Using the coordination of the buy back contract, both the manufacturer and the retailer were satisfied and equilibrium was achieved. A conclusion was drawn from numerical simulations that the buy back contract can solve the profit allocation problem of supply chain equilibrium in a buyer＇s or seller＇s market. This sheds a new light on supply chain problems.
