提出风险偏爱值和条件风险偏爱值的概念;然后将其引入对具有风险偏爱特性的供应链优化与协调问题的研究,建立了随机需求下由具有不同风险偏爱程度的单个供应商与单个零售商组成的两级供应链的条件风险偏爱值模型和基于条件风险偏爱值的最优订购量模型及协调供应链的最优回购契约模型,并对模型进行了分析,揭示了供应商和零售商的风险偏爱程度对供应链协调、最优订购量、回购价格及供应链合作稳定性的影响;最后通过一个算例进一步验证了本文的研究结论。
This paper introduces the concept of risk preference value and conditional risk preference value, then introduces it into the optimization and coordination problem of supply chain with risk preference characteristics, and establishes the research results of supply chain optimization and coordination problem with risk preference characteristics under the condition of random demand by a single supplier with a different degree of risk preference and a single retailer Composed of the two-level supply chain risk preference value model and conditional risk preference value of the optimal order quantity model and the coordination of supply chain optimal repurchase contract model, and the model was analyzed to reveal the suppliers and retailers The degree of risk preference on supply chain coordination, optimal order quantity, repo price and the stability of supply chain cooperation. Finally, an example is used to further verify the conclusion of this paper.
