产出和需求不确定下三级供应链契约协调模型

Three-echelon supply chain contract coordination model with uncertainties of yield and demand

研究基于供应商和制造商随机产出以及零售商随机需求的单一供应商、制造商和零售商组成的三级供应链契约协调问题,构建并分析集中和分散条件下供应链系统的最优决策模型,证明随机产出和需求下运用风险共担契约可以使分散期望利润达到集中决策的水平.在数值算例中,通过模型和契约参数的分析,阐述了风险共担契约协调的有效性.

The contract coordination issue of a three-echelon supply chain is studied, which consists of the single supplier,the manufacturer and the retailer based on both the supplier and manufacturer random yield and the retailer random demand.The optimal decision models of the supply chain system are established and analyzed under the condition of centralization and decentralization. By using the risk-sharing contract, the expected profit of decentralization can be proved to be at the level of that of centralization decision based on random yield and demand. Finally, the analysis of the parameter of model and contract in the numerical example show the effectiveness of the risk-sharing contract coordination.
