摘　　要：针对供应链中断问题,提出2个供应链恢复策略—供应商预设紧急库存策略和制造商进行产品变更策略,同时还考虑了紧急库存的存储成本和变更后产品的退货率。为了最大化制造商的利润和顾客满意度,分别建立了单目标和双目标模型。将2个模型中的优化问题转换为混合整数规划问题并基于ILOG CPLEX给出了相应的求解算法。仿真结果表明:所提的中断恢复策略不仅可以有效地帮助供应商止损,并且可以很好地满足市场需求。Aiming at supply chain disruptions, two effective supply chain recovery strategies are proposed,namely, a supplier’s preset emergency inventory strategy and a manufacturer’s product change strategy,meanwhile, emergency inventory storage cost and products return rate after change are also taken into consideration. In order to maximize the manufacturer’s profit and customer satisfaction, a single-objective model and a bi-objective model are established, respectively. The optimization problems in the two models are transformed into mixed integer programming problems, moreover, corresponding solution algorithms are presented based on ILOG CPLEX. The simulation results show that the disruption recovery strategies proposed can not only help suppliers to reduce losses effectively, but also meet the market demands well.
