Abstract

We present a novel algorithm for separating facet-inducing inequalities for the convex-hull of the union of polytopes representing a disjunctive constraint of special structure. It is required that the union of polytopes admit a certain network flow representation. The algorithm is based on a new, graph theoretic characterization of the facets of the convex-hull. Moreover, we characterize the family of polytopes that are representable by the networks under consideration. We demonstrate the effectiveness of our approach by computational results on a set of benchmark problems.

Abstract Image

利用网络流量表示法对不相关约束进行面分离
我们提出了一种新颖的算法,用于分离表示特殊结构的互不相容约束的多边形联合体凸壳的面诱导不等式。该算法要求多边形的联合体具有一定的网络流表示。该算法基于凸壳面的一种新的图论特征。此外,我们还描述了可由所考虑的网络表示的多边形族。我们通过一组基准问题的计算结果证明了我们方法的有效性。

期刊介绍: The Annals of Operations Research publishes peer-reviewed original articles dealing with key aspects of operations research, including theory, practice, and computation. The journal publishes full-length research articles, short notes, expositions and surveys, reports on computational studies, and case studies that present new and innovative practical applications. In addition to regular issues, the journal publishes periodic special volumes that focus on defined fields of operations research, ranging from the highly theoretical to the algorithmic and the applied. These volumes have one or more Guest Editors who are responsible for collecting the papers and overseeing the refereeing process.
