考虑价格竞争及风险规避的闭环供应链协调机制研究

On Coordination Mechanisms Governing the Closed-Loop Supply Chain in View of Price Competition and Risk Aversion Factors

以1个供应商和2个价格竞争零售商组成的闭环供应链为研究对象,并考虑供应商和零售商双向风险规避特性,研究了闭环供应链的协调机制问题。通过对分散决策模型和集中决策模型的分析,构建了收益共享契约协调模型。最后,通过算例仿真分析了批发价格、销售价格、回收价格与风险规避系数的关系,并验证了模型的科学性和合理性。

A study has been carried out on the coordination mechanisms governing the closed-loop supply chain,with one supplier and two competitive retailers subjects under investigation, and a bidirectional risk aversion involved in the process taken into account. A coordination model of revenue sharing contract has been established on the basis of the analysis of characteristics of decentralized decision-making model and centralized decision-making model. Thus, the feasibility and rationality of the model have been verified by analyzing with numerical simulations the inter-relationship between the wholesale price, sales price, recycling price and the coefficient of risk aversion.
