The P-Center Problem under Uncertainty
Facility location decisions play a prominent role in strategic planning of many firms, companies and governmental organizations. Since in many real-world facility location problems, the data are subject to uncertainty, in this paper, we consider the P-center problem under uncertainty of demands. Using Bertsimas and Sim approach, we develop a robust model of the problem as an integer programming...

متن کاملUnweighted p-center problem on extended stars
An extended star is a tree which has only one vertex with degree larger than two. The -center problem in a graph asks to find a subset of the vertices of of cardinality such that the maximum weighted distances from to all vertices is minimized. In this paper we consider the -center problem on the unweighted extended stars, and present some properties to find solution.
متن کاملThe p-hub center allocation problem
The p-hub center problem is to locate p hubs and to allocate non-hub nodes to hub nodes such that the maximum travel time (or distance) between any origin–destination pair is minimized. We address the p-hub center allocation problem, a subproblem of the location problem, where hub locations are given. We present complexity results and IP formulations for several versions of the problem. We esta...
متن کاملThe p-Center Problem with Connectivity Constraint
Let G(V, E, W) be a graph with n-vertex-set V and m-edge-set E in which each edge e is associated with a positive distance W(e). The p-Center problem is to locate some kind of facilities at p vertices of G to minimize the maximum distance between any vertex and the nearest facility corresponding to that vertex. This paper proposes an additional practical constraint. We restrict that the p verti...
