This paper studies the network design for a multi-product, multi-echelon and multi-period CLSC accounting for decisions on the manufacture of new products and remanufactured versions of the new products. It is important to note that the design for remanufacture is taken into account in order to facilitate the product remanufacture and, thus, assures products and/or components value over time. This work proposes a mathematical formulation to identify the optimal network and product design accounting for products life cycle while maximizing the total network profit. The developed approach determines a) the network design from a general network superstructure that includes raw material suppliers, factories, distribution centers, customer, collection centers, dismantlers, repairing centers, final disposal locations and dismantling centers, b) the design for new products and the design for remanufactured products, c) the selling prices for remanufactured products and d) the number of units of used products to be taken back. In addition, environmental aspects are addressed by modeling the CO2 emissions. The effectiveness of the proposed formulation is shown using a case study from a European consumer goods company
