Description: The Vehicle Routing Problem with Time Windows (VRPTW) deals with the distribution of goods between depots and customers using vehicles. The vehicles have a limited capacity. Each customer has to be supplied within the time window associated with the customer.

The model formulation follows Desrochers et al. (1988), pp. 67-68.

By default this project uses the data instance ‘R106.25’ from the Solomon set at:

More instances are available as cases.
