The distances considered are the great-circle distances between the British urban areas, which are the nodes, and are expressed in miles. The demands are the number of citizens, in thousands. The compressed file includes the following files: - UKMainIsland.coords.txt, geographical coordinates of the nodes, used to calculate the distances; - UKMainIsland.PMSol.txt, optimal solutions to the capacitated p-median problem, expressed as:

; - UKMainIsland.txt, specifies the number of nodes, the number of arcs, distance d_ij for every arc (i,j) expressed as (note that only the triangular matrix is provided), demand of each node; - UKMainIsland.GIF, a graphical representation of the dataset. This dataset has been originally developed for the article \"Optimizing protection strategies for supply chains: comparing classic decision making criteria in an uncertain environment\" by Liberatore and Scaparra, currently under review for Annals of AAG, to provide realistic data to test fortification/interdiction models in location analysis. delivered on: 01.04.2010 Fileupload successfully confirmed!
