The shortage of natural resources, the need to take into account societal considerations, the emergence of new government regulations and the necessity to maintain and/or improve the economic benefit of the supply chain, have created a growing awareness on academia as well as industries towards the development of closed-loop supply chains (CLSCs), where explicitly products' life-cycles are accounted for. Concentrating on the problems of the product and network design for a multi-product, multi-echelon and multi-period CLSC, in this work a two-stage stochastic mixed integer linear model incorporating uncertainty on the quality and quantity of the return flows is proposed. In addition, risk management related to critical uncertain parameters is performed, where a conditional value at risk (CVaR) concept is applied to supply chain profits. The formulation considers decisions associated with the network design and, simultaneously, with the products to manufacture (new and remanufactured) and their associated raw materials (new and recovered). A network superstructure is considered accounting for two types of customers (first and second markets), raw material suppliers, factories, distribution centers, customer demands, recovery centers, recycle centers, final disposal locations and re-distribution centers. Optimal solutions with high economic and environmental benefits are obtained where the advantages of using the proposed approach are shown. A case study from a European consumer goods company is explored.

不确定收益流下产品与闭环供应链设计的集成决策

自然资源的短缺,需要考虑到社会因素,新的政府法规的出现以及维持和/或改善供应链的经济利益的必要性,使人们对学术界和工业界的意识日益增强。闭环供应链(CLSC)的发展,其中明确考虑了产品的生命周期。针对多产品,多级,多周期CLSC的产品和网络设计问题,在这项工作中,提出了一个两阶段随机混合整数线性模型,该模型包含了回流质量和数量的不确定性。此外,还执行与关键不确定参数有关的风险管理,其中将条件风险值(CVaR)概念应用于供应链利润。该表述考虑与网络设计相关的决策,并同时考虑与要制造的产品(新的和再制造的)及其关联的原材料(新的和回收的)相关的决策。网络上层建筑考虑了两种类型的客户(第一和第二市场),原材料供应商,工厂,分销中心,客户需求,回收中心,回收中心,最终处置地点和再分配中心。获得了具有高经济和环境效益的最佳解决方案,其中显示了使用所建议方法的优势。探索了一家欧洲消费品公司的案例研究。以及要制造的产品(新的和再制造的)及其相关的原材料(新的和回收的)。网络上层建筑考虑了两种类型的客户(第一和第二市场),原材料供应商,工厂,分销中心,客户需求,回收中心,回收中心,最终处置地点和再分配中心。获得了具有高经济和环境效益的最佳解决方案,其中显示了使用所建议方法的优势。探索了一家欧洲消费品公司的案例研究。以及要制造的产品(新的和再制造的)及其相关的原材料(新的和回收的)。网络上层建筑考虑了两种类型的客户(第一和第二市场),原材料供应商,工厂,分销中心,客户需求,回收中心,回收中心,最终处置地点和再分配中心。获得了具有高经济和环境效益的最佳解决方案,其中显示了使用所建议方法的优势。探索了一家欧洲消费品公司的案例研究。最终处置地点和再分配中心。获得了具有高经济和环境效益的最佳解决方案,其中显示了使用所建议方法的优势。探索了一家欧洲消费品公司的案例研究。最终处置地点和再分配中心。获得了具有高经济和环境效益的最佳解决方案,其中显示了使用所建议方法的优势。探索了一家欧洲消费品公司的案例研究。
