摘　　要：针对制造商存在生产规模不经济的情况,分别构建制造商回收和零售商回收的分散式决策系统和集中式决策系统,研究了生产成本扰动下闭环供应链的应急管理问题。结果表明:当产品的生产成本发生扰动较小时,分散式决策系统和集中式决策系统在稳定运营环境下制定的各类均衡决策均具鲁棒性,且随着规模不经济弹性系数的增大,各企业保持稳定运营环境下最优均衡决策具鲁棒性的扰动区间也在不断增大;而当产品的生产成本发生扰动较大时,应根据其扰动方向调整零售价格,按反方向调整产品需求量并保持废旧品回收价格不变;在应急回收模式选择中,制造商直接进行废旧品回收较优;设计的应急收益费用共享契约能够实现稳定运营环境下和发生扰动后闭环供应链的协调。Aiming at the production diseconomies scale of manufacturer,the decentralized decision-making system and centralized decision-making system of manufacturer recycling and retailer recycling are constructed respectively.The emergency management problem of closed-loop supply chain under production cost disturbance is studied.The results show that:when the production cost of products is small,all kinds of equilibrium decisions made by decentralized decision-making system and centralized decision-making system under stable operation environment are robustness,and with the increase of the scale diseconomies elasticity coefficient,the disturbance interval with robustness of the optimal equilibrium decision-making in the stable operation environment is also increasing.When the production cost of the product is disturbed greatly,the retail price should be adjusted according to the disturbance direction,the product demand should be adjusted in the opposite direction,and the recycling price of waste products should be remain unchanged.In the selection of emergency recovery mode,it is better for manufacturers to directly recycle waste products.The designed contract can realize the coordination of the closed loop supply chain under normal operating environment and after disturbance.
