随机需求下双渠道供应链的改进回购契约协调

A New Buy-Back Contract Coordinating Dual-Channel Supply Chain under Stochastic Demand

考虑市场需求是非线性随机的且受零售商努力影响的一般情形,建立由一个制造商与一个零售商组成的双渠道供应链Stackelberg博弈模型,研究设计协调双渠道供应链的引入努力成本分担系数的改进回购契约,结果表明,只要引入努力成本分担系数的改进回购契约参数取值恰当,双渠道供应链就能够实现协调.研究结论具有一定的理论与现实指导意义.

The conflict between the manufacturer and the retailer except the double marginalization is an important issue in order to coordinate the dual-channel supply chain.By developing a dual-channel supply chain model with a manufacturer and a retailer under the Stackelberg game theory,this paper designed a new buy-back contract,which incorporates the parameter describing the share of effort cost.And the result shows that,as long as the value of the contract parameters meet certain con-ditions,the dual-channel supply chain can achieve coordination.The research conclusion has a certain theoretical and practical value.
