Abstract
We consider a Network Design problem where edges have to be activated at minimum cost while ensuring that the resulting graph contains at least k disjoint paths linking a given set of origin-destination pairs. In addition, those paths are constrained in terms of maximum number of intermediate nodes. We consider alternative Integer Programming formulations for the problem and computationally evaluate them on a large benchmark of instances having different features. Finally, we extend our analysis to the case in which the paths must be vertex disjoint. (c) 2024 Elsevier B.V.
