Résumé:
Given a graph G, the Shortest Capacitated Paths Problem (SCPP) consists of determining a set of paths of
least total length, linking given pairs of vertices in G, and satisfying capacity constraints on the arcs of G.
We formulate the SCPP as a 0-1 linear program and study two Lagrangian relaxations for getting lower
bounds on the optimal value. We then propose two heuristic methods. The first one is based on a greedy
approach, while the second one is an adaptation of the tabu search meta-heuristic.Keywords
