  • An integer programming approach for the 2-schemes strip cutting problem with a sequencing constraint

    Optimization and Engineering: Volume 16, Issue 3 (2015), Page 605-632

    We study integer programming formulations for the 2-schemes strip cutting problem with a sequencing constraint (2-SSsc) considered by Rinaldi and Franz. The 2-SSsc arises in the context of corrugated cardboard production, which involves cutting strips of large lengths into rectangles of at most (usually) two different lengths. Because of buffer restrictions, in the 2-SSsc these strips must be sequenced in such a way that, at any moment, at most two types of items are in production and not…

    We study integer programming formulations for the 2-schemes strip cutting problem with a sequencing constraint (2-SSsc) considered by Rinaldi and Franz. The 2-SSsc arises in the context of corrugated cardboard production, which involves cutting strips of large lengths into rectangles of at most (usually) two different lengths. Because of buffer restrictions, in the 2-SSsc these strips must be sequenced in such a way that, at any moment, at most two types of items are in production and not completed yet. This problem is NP-hard. We present four integer programming formulations for this problem, and our computational experiments with real-life instances show that one of them has a very tight integrality gap. We propose a heuristic procedure based on this formulation and present computational experience showing that this procedure finds very good primal solutions in small running times.
