In this paper, we show how to extend solution methods for vehicle-routing problems with
intermediate stops (using the example of an Adaptive Variable Neighborhood Search …

There are numerous practical vehicle routing applications in which vehicles have to stop at
certain facilities along their routes to be able to continue their service. At these stops, the …

In the present research, a new variant of the Vehicle Routing Problem (VRP), the

This paper models and solves a new transportation problem of practical importance; the
Consistent Vehicle Routing Problem with Profits. There are two sets of customers, the …

We consider several vehicle routing problems (VRP) with profits, which seek to select a
subset of customers, each one being associated with a profit, and to design service …

We consider a vehicle routing problem which seeks to minimize cost subject to service level
constraints on several groups of deliveries. This problem captures some essential …
