考虑努力因素的供应链收益共享演化契约

Supply Chain Revenue-Sharing Evolvement-Contract with Sales Effort Effects

在需求随机、努力水平影响需求的供应链环境里,在传统供应链收益共享契约基础上构建了一种演化契约。并在委托代理框架下,对该演化契约进行了研究。首先分析了销售商的努力因素对收益共享契约的影响,得出了销售商努力水平反应函数及最优投入值;其次,研究得出了供应商在收益共享契约中,向销售商所提供的最优收益共享比例,以及最优的分担销售商的努力成本比例;再次,论证了本文所研究的收益共享演化契约可以实现供应链协调;最后,通过算例分析验证本文研究结论的有效性。

In a single-period two-stage supply chain facing stochastic effort dependent demand,we construct a evolvement-contract,and research on it by principal-agent theory.Firstly,the paper analyzes retailer＇s effort level＇s impact on supply chain revenue-sharing evolvementcontract,and gain retailer＇s effort level＇s reaction function and its optimal value;secondly,the paper gets the optimal revenue-sharing coefficient and cost-sharing one,which the supplier give to the retailer;Then,study in the paper indicates that the supply chain revenue-sharing evolvement-contract can realize supply chain collaboration;Finally,we validate and illuminate the research conclusion by numerical analyzing.
