This study investigates a new phenomenon of degeneracy in the multi-source Weber problem. This phenomenon relates to the existence of solutions in which one or more facilities are out of use; that is, no demands (or customers) are allocated to these facilities. We show that a significant portion of solutions is degenerate when large numbers of new facilities are being considered. Computational res...
