产量和需求随机下基于收益共享契约的供应链决策

针对产量和需求都随机的供应链, 在条件风险值(CVaR) 的度量准则下, 建立具有风险规避型零售商的供应链最优决策模型, 探讨收益共享契约下供应链协调的条件, 并进行了数值分析. 研究结果表明, 零售商的风险规避以及产量的不确定性将降低最优订购量及供应链效益; 收益共享契约可以优化产量和需求随机条件下的供应链运作效率, 并在一定条件下使供应链达到协调.

Decision of supply chain based on revenue-sharing contract with random yield and random demand

Under the conditional value-at-risk(CVaR) criterion, an optimal decision-making model of the supply chain with the risk-averse retailer is built under random yield and random demand. The coordination conditions of the supply chain with revenue sharing contract are analyzed, and a numerical example is analyzed to verify the theory. The results show that the risk-aversion of the retailer and the uncertainty of yield can reduce the optimal order and the benefit of the supply chain. The revenue sharing contract can improve the benefit of the supply chain with random yield and random demand, and coordinate the supply chain under some conditions.
