Die Beiträge zum vorliegenden Band befassen sich mit der Entwicklung des Nachdenkens über den Raum als Dimension wirtschaftlichen Handelns. Ihr Zeithorizont reicht von der Stadtentwicklungstheorie Giovanni Boteros im 16. Jahrhundert bis zur »Neuen Ökonomischen Geographie« alias...

Let a connected undirected graph G  =  (V, E) be given. In the classical p-median problem we want to find a set X containing p points in G such that the sum of weighted distances from X to all vertices in V is minimized. We consider the semi-obnoxious case where every vertex has either a...

The inverse p-median problem with variable edge lengths on graphs is to modify the edge lengths at minimum total cost with respect to given modification bounds such that a prespecified set of p vertices becomes a p-median with respect to the new edge lengths. The problem is shown to be strongly <InlineEquation ID="IEq1">...</inlineequation>
