基于收益共享与努力成本共担的供应链期权销量担保契约

Supply Chain Option Sale-surety Contract Based on Revenue Sharing and Effort Cost partaking

对销售商和供应商组成的两级供应链,在需求为随机且与努力水平相关的市场环境下,建立了供应链期权销量担保契约模型,提供了一种基于期望损失的期权定价方法,分析了努力因素对供应链协调的影响。研究得出在考虑努力因素时单纯的期权销量契约无法实现供应链协调,为此,引入收益共享和努力成本共担策略,对原契约加以修正,当收益共享和努力成本共担比例满足一定条件时,则可以实现供应链协调,并进一步讨论了使修正契约具有帕累托优势的条件。最后,提供了一种模型优化分析方法,并通过算例分析验证了研究结论的有效性。

In a single-period two-stage supply chain facing stochastic effort dependent demand, we construct a model of sale-surety contract with effort dependent demand, and give a method of surety-optlon＇s pricing based on expected loss, then analyze the influence of effort on supply chain collaboration. We obtain the single contract does not coordinate the supply chain. To deal with it, we modify the single contract with revenue-sharing and effort cost-partaking, and it can make a supply chain coordinate and reach Pareto optimality. Finally, a optimal method of model and case-analysis are given.
