Benders decomposition has been widely used for solving network design problems. In this
paper, we use a branch-and-cut algorithm to improve the separation procedure of Gabrel et …

In this article, we study capacitated network design problems. We unify and extend
polyhedral results for directed, bidirected, and undirected link capacity models. Valid …

Given a general mixed integer program, we automatically detect block structures in the
constraint matrix together with the coupling by capacity constraints arising from multi …

We study a planning problem arising in SDH/WDM multi-layer telecommunication network
design. The goal is to find a minimum cost installation of link and node hardware of both …

Telecommunication transport networks consist of a stack of technologically different
subnetworks, so-called layers, which are strongly interdependent. For example, one layer …

In this paper, we present a model-based optimization approach for the design of multi-layer
networks. The proposed framework is based on a series of increasingly abstract models …

This article provides an overview about the main results and findings developed in the
dissertation of the author [8]. In this thesis, we develop methods in mathematical optimization …

In this paper we study capacitated network design problems, differentiating directed,
bidirected and undirected link capacity models. We complement existing polyhedral results …

The planning of a whole power plant involves diversivied specializations in engineering and
can take up to several years. Within the planning procedure the routing of the high pressure …

We present two studies to benchmark Routing and Wavelength Assignment (RWA)
strategies which have been developed for dynamically controlled optical networks. In a first …
