We call the problem of locating <em>p</em> centers over <em>k</em> underlying networks corresponding to <em>k</em> periods the <em>k-Network p-Center</em> problem. The problem is considered when, in each period, the network satisfies the triangle inequality. In this paper, we provide a polynomial time 3-approximation algorithm for <em>Δ</em> <em>k-Network p-Center</em> for the case <em>k</em>=2. We discuss generalizations inspired by this problem to other optimization problems with multiple underlying networks and the objective of finding a single solution that varies as little as possible from the optimum for each network. The additional combinatorial problems discussed include: sorting; perfect matching; shortest path; minimum spanning tree; and minimum cut.

Given a set of candidate locations and the concentrator capacities, the problem is to answer the following related questions. How many concentrators should be used? Where should they be located? Which users are to be assigned to each concentrator? A Lagrangian relaxation is used to obtain lower bounds for this problem. The Lagrangian relaxation is complemented by a tabu search (TS) metaheuristic.
