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 Vehicle Routing Problem (VRP) is a well-known research line in the optimization
research community. Its different basic variants have been widely explored in the literature …

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 …

Abstract In the Dial-a-Ride-Problem (DARP) a fleet of vehicles provides shared-ride services
to users specifying their origin, destination, and preferred arrival time. Typically, the problem …

The solution of a vehicle routing problem calls for the determination of a set of routes, each
performed by a single vehicle which starts and ends at its own depot, such that all the …

Dial-a-ride problems deal with the transportation of people between pickup and delivery
locations. Given the fact that people are subject to transportation, constraints related to …

Due to an increased interest in small to medium scale liquefied natural gas (LNG) use, a
mathematical model has been developed to aid the decision making on tactical aspects in …

We consider a family of rich vehicle routing problems (RVRP) which have the particularity to
combine a heterogeneous fleet with other attributes, such as backhauls, multiple depots …

Time dependencies of travel speeds in time-dependent vehicle routing problems (TDVRPs)
are usually accounted for by discretizing the planning horizon into several time periods …
