Benchmark instances for the Cumulative Capacitated Vehicle Routing Problem with Priority Indexes

Two instance groups for the Cumulative Capacitated Vehicle Routing Problem with Priority Indexes. The first group considered the MT-DMP instances proposed by Angel-Bello et al. (2013) and used by Nucamendi-Guillén et al. (2018) for the classical CCVRP, ranging from 10 to 30 nodes and 2 to 3 vehicles. For them, the original capacities were adjusted to model a heterogeneous fleet. The second group of instances comprises an adaptation of the ones proposed by Taillard (1999) for the Capacitated Vehicle Routing Problem considering a heterogeneous fleet ranging from 20 to 100 nodes and 3 to 18 vehicles. They were adapted to consider a priority index for each of the nodes based on a "triage" model, ranging from 1 to 5, using a similar distribution for each priority level. The referred instances provide the capacities for each vehicle.
