基于CVaR和期末二次订购的供应链协调模型

Research on Coordination Models Based on the CVaR and the Supply Chain of the Second Season-end Ordering

运用条件风险值CVa R度量准则,考察了两生产模式下风险规避且有促销努力的零售商和风险中性制造商的回购契约协调问题。讨论了供应链各成员的策略分析和如何利用回购契约协调供应链,然后分析了延期供给率、零售商风险规避系数和回购价格、两生产模式下的不同批发价格等参数对供应链各成员决策的影响。研究发现引入成本分担机制的回购契约能否协调供应链与零售商的风险规避程度有关。最后通过数值仿真验证了文中的主要结论,并得出一些管理启示。

Using conditional value-at-risk measure criterion, this paper discusses an issue of whether a repur- chase contract can Coordinate supply chains between a risk-averse retailer and a risk-neutral manufacturer under two production modes, Firstly it discusses how to make a strategy analysis and coordinate the supply chain by u- sing repurchase contract among supply chain members. Then it analyzes some influences on decision-making for a supply chain member, such as delayed supply rate, risk aversion coefficient of retailer, repurchase price, the wholesale price of the two production modes and so on. In conclusion, it shows that whether a repurchase con- tract with cost-sharing mechanism can coordinate supply chains is related to the degree of the risk aversion for a retailer. Finally, the numerical simulation validates the main conclusion and obtains some managerial implications.
