In Piñeyro and Viera (2010) (Int. J. Prod. Econ. 124 (2), 2010, 482–488) we investigate a lot-sizing problem with different demand streams for new and remanufactured items, in which remanufactured products can be substituted by new products, but not vice versa. In this note we correct some...

We investigate a lot-sizing problem with different demand streams for new and remanufactured items, in which the demand for remanufactured items can be also satisfied by new products, but not vice versa. We provide a mathematical model for the problem and demonstrate it is NP-hard, even under...

Background: The remanufacturing plan of perfect cost makes reference to the remanufacturing plan of an optimal solution of the economic lot-sizing problem with remanufacturing (ELSR). In this paper, we address the problem of determining the quantities of the remanufacturing plan of perfect cost...

We address the economic lot sizing problem with product returns and remanufacturing. For this problem we provide a new theoretical result about the form of the optimal solutions that can be considered a generalization of the well-known zero-inventory property. Based on this result we suggest an...

We address a production-remanufacturing planning problem of a single item with recovery targets stated as a lower bound on the numbers of returns that must be remanufactured. This problem can arise in practice if there are legal or market pressures. We show that this problem extension can be...
