On the Linear Relaxation of the p-Median Problem II: Directed Graphs

We study a well-known linear programming relaxation of the p-median problem. We give a characterization of the directed graphs for which this system of inequalities defines an integral polytope. Our proof uses a similar result on oriented graphs that we gave in [2].
