The Vehicle Routeing Problem [PDF]

open access: possibleLogistics Information Management, 1994
Reports on a study of a vehicle routeing problem as a pilot project. Outlines the motivation to embark on such an experimental study, the data collection process, the software, and the problems detected. Summarizes the gains derived from the research and explains resistance.

The Vehicle Routing Problem with Conflicts

IFAC Proceedings Volumes, 2011
The Vehicle Routing Problem (VRP) is a classical problem for which several exact and approximation methods were proposed. In real life applications, such as in Hazardous Material transportation, transported items may be incompatible. This paper summarizes the first methods developed for this extension called the Vehicle Routing Problem with Conflicts ...

The multi-trip vehicle routing problem [PDF]

open access: possibleJournal of the Operational Research Society, 1998
The basic vehicle routing problem is concerned with the design of a set of routes to serve a given number of customers, minimising the total distance travelled. In that problem, each vehicle is assumed to be used only once during a planning period, which is typically a day, and therefore is unrepresentative of many practical situations, where a vehicle

The Consistent Vehicle Routing Problem

Manufacturing & Service Operations Management, 2009
In the small package shipping industry (as in other industries), companies try to differentiate themselves by providing high levels of customer service. This can be accomplished in several ways, including online tracking of packages, ensuring on-time delivery, and offering residential pickups. Some companies want their drivers to develop relationships

Vehicle Routing Problems

2018
Vehicle routing problems (VRP) [72, 50, 186] represent one of the most investigated combinatorial optimization problems [134], due to the problem complexity and their potential impact on real-world applications especially in logistics and supply chains.

The Vehicle Routing Problem

2002
The Vehicle Routing Problem covers both exact and heuristic methods developed for the VRP and some of its main variants, emphasizing the practical issues common to VRP. The book is composed of three parts containing contributions from well-known experts. The first part covers basic VRP, known more commonly as capacitated VRP.

On the Vehicle Routing Problem

2005
In the Vehicle Routing Problem (VRP), as in the Traveling Salesman Problem (TSP), we have a metric space of customer points, and we have to visits all customers. Additionally, every customer has a demand, a quantity of a commodity that has to be delivered in our vehicle from a single point called the depot.

Metaheuristics for Vehicle Routing Problems

2016
The basic problem of vehicle routing is a classical operations research problem, known to be NP-hard Leung et al., Eur J Op Res 225(2): 199–210, 2013, [64] and called the vehicle routing problem (VRP) or capacitated VRP (CVRP).It consists in determining a least-cost set of routes from a depot for a fleet of capacitated vehicles in order to meet the ...

The Skill Vehicle Routing Problem

2011
Given a (complete) directed network, where a skill level s j is associated with each node j other than the depot, stating requirements for the associated service call, and given a set of available technicians, each one operating at a certain skill level, we address the problem of defining the tour of each technician, each one starting and ending at the
