联合促销和风险规避下应对突发事件的供应链协调策略

针对联合促销和风险规避下考虑突发事件的供应链协调问题,应用条件风险值度量制造商和零售商的风险价值,引入回购契约协调供应链,分别构建应对常规和非常规突发事件的供应链协调模型.研究表明,常规突发事件下,订货量、促销和契约参数具有一定的稳定性,当需求扰动较大时,供应链协调被打破,而非常规突发事件下,需求扰动打破供应链协调,通过调整契约参数能够使供应链重新达到协调状态.

Disruption coordination under risk-averse supply chain and joint promotion strategy

For the coordination of the supply chain under demand disturbances with a risk-averse manufacturer and a risk-averse retailer, conditional value-at-risk is used to evaluate the manufacturers and the retailers'' degree of risk aversion and buy-back contract is introduced to establish supply chain coordination model under conventional and unconventional disruption.It is found that order quantity, promotion and contract decision have a certain degree of robustness under conventional disruption.If the demand disruption quantity is relatively large, conventional disruption leads to incoordination. While unconventional disruption surely leads to incoordination, by the adjustment of contract parameters, the supply chain can reach the coordination state again.
