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 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...

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...
