Polyhedral Analysis for the Uncapacitated Hub Location Problem with Modular Arc Capacities

Hande Yaman (hyaman***at***bilkent.edu.tr)

Abstract: We consider the problem of installing a two-level telecommunication network. Terminal nodes communicate with each other through hubs. Hubs can be installed on terminal nodes and they are interconnected by a complete network. Each terminal is connected to a hub node by direct links. The aim is to minimize the cost of installing hubs and links. We present valid and facet defining inequalities for this problem.

Keywords: hub location, polyhedral analysis, lifting
