Sandor P. Fekete, Joerg Schepers

摘要:

高维正交布局问题有着广泛的实际应用,包括布局、切割和调度。在解决这些包装问题的最优分支定界框架的背景下,它是至关重要的,有一个良好的和容易的最优解的界限。以前的努力已经产生了一些特殊的类这样的界限。不幸的是,其中一些界限有些复杂,难以概括。我们提出了一种新的方法来获得类的下界高维包装问题,我们的边界改进和简化了以前的文献中的几个著名的界限。此外,我们的方法提供了一个简单的框架,证明新的界限的正确性。

英文摘要:

Higher-dimensional orthogonal packing problems have a wide range of practical applications, including packing, cutting, and scheduling. In the context of a branch-and-bound framework for solving these packing problems to optimality, it is of crucial importance to have good and easy bounds for an optimal solution. Previous efforts have produced a number of special classes of such bounds. Unfortunately, some of these bounds are somewhat complicated and hard to generalize. We present a new approach for obtaining classes of lower bounds for higher-dimensional packing problems; our bounds improve and simplify several well-known bounds from previous literature. In addition, our approach provides an easy framework for proving correctness of new bounds.
