Festival Cleanup Instances for the Multi-Depot Multi-Trip Vehicle Routing Problem

Benchmark instances for the Multi-Depot Multi-Trip Vehicle Routing Problem (MDMTVRP) in the context of waste collection after large events. The set contains 24 synthetic festival instances in six size classes, ranging from 23 to 1000 collection points, with two depots each. The instances are stored in a text format compatible with the standard MDVRP benchmark format of Cordeau et al. (1997). Each node is described by an ID, x and y coordinates, a service time, and a demand. Depots are listed first, followed by the collection points. The instances were created for a master's thesis at the University of Vienna and are provided for reuse in vehicle routing research.
