title = "Multi-product Lot-Sizing Problem with Remanufacturing, Lost Sales and Sequence-Dependent Changeover Cost",
abstract = "This work studies a lot-sizing problem motivated by a textile remanufacturing company in Chile. In particular, we investigate a multi-product lot-sizing with remanufacturing, lost sales, and sequence-dependent changeover costs. The problem is first formulated as a mixed-integer linear program. Then, we adapted a known family of valid inequalities and proposed a new exponential family of valid inequalities taking advantage of the problem structure. We use them in a branch-and-cut algorithm to solve the problem. The preliminary numerical results show the proposed inequalities{\textquoteright} usefulness in strengthening the proposed formulation{\textquoteright}s linear relaxation and show that the method outperforms the generic branch-and-cut algorithm embedded in a stand-alone mathematical solver.",
