| Tiivistelmä: | Uncapacitated network design problems are addressed that are relevant to production and telecommunications planning. A dual-based approach is introduced. It is shown how the ascent procedure can be viewed as a generalization of the shortest path algorithm and of the dual-ascent procedure of the network problem, which generalizes the ascent algorithm for uncapacitated plant location, as well as the directed spanning tree algorithm. The dual-ascent heuristic solution procedure computes a lower bound for the design problem, and also provides information for determining a feasible design. A drop-add procedure improves the quality of the solution. |
