以制造商是风险中性、分销商和销售商具有下行风险特性的三层供应链系统为背景,研究了风险规避特性对供应链协调性的影响,证明了Downside-Risk测度下三层供应链不协调。依据供应链协调的基本思想和方法,将补偿政策与收益共享、产品回购等契约相结合,建立了Downside-Risk测度下三层供应链协调模型,设计了风险共享契约,既能满足下行风险约束,又保证供应链参与方利润均有增量,实现了Downside-Risk测度下供应链的协调和风险控制,最后通过算例验证了契约的可行性和有效性。
Based on the three-tier supply chain system where the manufacturer is risk-neutral and the distributors and vendors have the downside risk characteristics, the effect of the risk-aversion characteristic on the supply chain coordination is studied. It is proved that the three-level supply chain under the Downside-Risk measure Uncoordinated. According to the basic idea and method of supply chain coordination, combining the compensation policy with the contract of revenue sharing and product repurchase, the coordination model of the three-tier supply chain under Downside-Risk measure is established and the risk-sharing contract is designed, which can not only meet the downside risk Constraints, and ensure that the profits of suppliers in the supply chain are increased. The supply chain coordination and risk control under the Downside-Risk measure are realized. Finally, an example is given to verify the feasibility and effectiveness of the contract.
