Enhanced formulations and branch-and-cut for the two level network design problem with transition facilities

Gollowitzer, Stefan; Gouveia, Luis; Ljubić, Ivana - In: European Journal of Operational Research 225 (2013) 2, pp. 211-222

We consider a new combinatorial optimization problem that combines network design and facility location aspects. Given a graph with two types of customers and two technologies that can be installed on the edges, the objective is to find a minimum cost subtree connecting all customers while the...
