Abstract:

Starting from the core enterprise of closed loop supply chain and based on the life cycle theory of high-salvage perishable product, this paper builds a double channel closed-loop supply chain network model under uncertain environment. The interval chance-constraint method is used to deal with the uncertain parameter, and the target value under the different confidence level is analyzed. It is found that the model has certain robustness. The simulation results can provide a reference for decision makers in facility location, product pricing, recovering time and product sales.

Key words: high-salvage perishable product, life cycle, closed-loop supply chain, interval programming, chance-constrained

摘要：

从闭环供应链的核心企业出发，基于高残值易逝性产品生命周期理论，构建了不确定环境下的双渠道闭环供应链网络模型。采用了区间机会约束方法处理模型中的参数不确定性，分析不同置信水平条件下的目标值，发现该模型具有一定的稳健性。模型仿真结果能为决策者在设施选址、产品定价、回收时间、产品销量等方面提供参考。
