生产规模不经济闭环供应链的应急决策研究

Study on Disruption Decision-Making of Closed-Loop Supply Chain with Diseconomies of Production Scale

摘要: 针对由单一回收废旧品的制造商和单一销售产品的零售商所组成的生产规模不经济闭环供应链，在突发事件干扰其最大市场需求规模发生扰动的情况下，研究了系统的应急均衡决策问题。结果表明：相比较正常运营环境的均衡决策，当扰动程度不大时，产品的订购/销售量及废旧品的回收量均具鲁棒性；当扰动程度较大时，均应按扰动方向调整产品的订购/销售量及废旧品的回收量；当减少程度很大时，闭环供应链系统会被破坏。

Abstract: The problems of disrupting decision and coordination are researched for closed-loop supply chain with one manufacture exhibiting diseconomies of production scale and one retailer collecting used products under demand disruption. The results show that compared with the equilibrium decision of normal operating environment, when the degree of disturbance is not large, the order quantity/sales volume and the amount of waste products recovered are robust. When the degree of disturbance is large, it should be adjusted according to the disturbance direction, the order/sales volume of the product and the amount of recycling of the waste product; when the degree of reduction is larger, the closed-loop supply chain system will be destroyed.
