Abstract

The network design problem appears in a variety of telecommunication and transportation applications.

We consider a concentrator-based network in a 2-level hierarchical configuration. First level is formed by a set of terminal nodes, and second level is formed by a set of concentrators. Concentrators are assigned to the root node. Each edge between two nodes has two parameters - constant and variable cost, which can be interpreted as length and capacity of the line. Each concentrator has a constant cost of its accommodation at this node. The optimization problem is to select a subset of concentrators and a subset of edges that minimize the sum of the constant and variable costs.
