带序约束的高维Packing

Higher-Dimensional Packing with Order Constraints

Sandor P. Fekete, Ekkehard Koehler, Juergen Teich

摘要:

我们提出了第一个精确的研究与顺序约束的高维包装问题。这类问题自然出现在物流或计算机体系结构等应用中,可以解释为调度问题的高维概括。使用图论结构来描述可行解,我们开发了一种新的精确分支定界算法。这扩展了Fekete和Schepers以前的工作;一个关键的工具是一个新的序理论表征的可行扩展的偏序到一个给定的互补图,是量身定制的用于在分支定界环境。计算结果验证了该方法的有效性。

英文摘要:

We present a first exact study on higher-dimensional packing problems with order constraints. Problems of this type occur naturally in applications such as logistics or computer architecture and can be interpreted as higher-dimensional generalizations of scheduling problems. Using graph-theoretic structures to describe feasible solutions, we develop a novel exact branch-and-bound algorithm. This extends previous work by Fekete and Schepers; a key tool is a new order-theoretic characterization of feasible extensions of a partial order to a given complementarity graph that is tailor-made for use in a branch-and-bound environment. The usefulness of our approach is validated by computational results.
