Instances for depot location in realistic and asymmetric vehicle routing problems (ACVRP)

Instances used in Rodríguez A., Ruiz R., “A study of the effect of the depot location in realistic and asymmetric vehicle routing problems”, can be downloaded here:   case ACVRP – depot (30 MB) 540 location files, for different number of nodes on several territories and depot locations. 540 distance matrix files (real asymmetric). 360 demand and max.capacity files.   » explanation of the ACVRP – depot  files format here.     Note: The files were tested 100% ok in their extraction with several software. You can to extract the files with: 7-Zip (Windows), IZArc (Windows), Unarchiver (Mac OS X) or other software compatible with 7z compress format. For more information, please contact. […]
