文章在模糊的环境下对单周期二层的闭环供应链的定价决策问题进行了研究。在研究中将不确定变量刻画为模糊变量,并在模型中考虑了回收再利用率对闭环供应链的影响。在集中决策与分散决策的情形下对模型进行了分析,得到了最优的定价决策。 In the fuzzy environment, the paper studies the pricing decision-making problem of closed-loop supply chain with single-cycle and second-level. In the study, the uncertain variables are described as fuzzy variables, and the impact of recycling rate on the closed-loop supply chain is taken into account in the model. In the centralized decision-making and decentralized decision-making under the circumstances of the model was analyzed, the optimal pricing decision was obtained.
