    We consider a dynamic lot sizing model in which end products to satisfy demands are obtained by remanufacturing m types of cores, where m ≥ 1, or manufacturing from raw materials, and in the model, we have separate setup costs for manufacturing and remanufacturing. As is widely known, remanufacturing is an environmental preferable choice compared … Read more

    We consider an uncapacitated multi-item multi-echelon lot-sizing problem within a remanufacturing system involving three production echelons: disassembly, refurbishing and reassembly. We seek to plan the production activities on this system over a multi-period horizon. We consider a stochastic environment, in which the input data of the optimization problem are subject to uncertainty. We propose a … Read more
