It has been around 30 years since the heterogeneous vehicle routing problem was
introduced, and significant progress has since been made on this problem and its variants …

The purpose of this paper is to describe industrial aspects of combined fleet composition
and routing in maritime and road-based transportation, and to present the current status of …

Vehicle routing problems (VRPs) form a class of combinatorial problems with wide practical
applications. While previous heuristic or learning-based works achieve decent solutions on …

This paper deals with the Heterogeneous Fleet Vehicle Routing Problem (HFVRP). The
HFVRP is NP-hard since it is a generalization of the classical Vehicle Routing Problem …

In the well-known Vehicle Routing Problem (VRP) a set of identical vehicles, based at a
central depot, is to be optimally routed to supply customers with known demands subject to …

Electric Vehicle (EV)-based parcel delivery is getting much more popular these days due to
EVs being eco-friendly and sustainable. One well-known problem in the literature to study …

We consider a vehicle routing problem with a heterogeneous fleet of vehicles having various
capacities, fixed costs and variable costs. An approach based on column generation (CG) is …

This paper deals with the Heterogeneous Fleet Vehicle Routing Problem (HFVRP). The
HFVRP generalizes the classical Capacitated Vehicle Routing Problem by considering the …

The vehicle routing problem (VRP) plays an important role in the distribution step of supply
chains. From a depot with identical vehicles of limited capacity, it consists in determining a …

We study a time-constrained heterogeneous vehicle routing problem on a multigraph where
parallel arcs between pairs of vertices represent different travel options based on criteria …
