Vehicle routing problems have been the focus of extensive research over the past sixty years, driven by their economic importance and their theoretical interest.
Abstract: We consider a common variant of the vehicle routing problem in which a vehicle fleet delivers products stored at a central depot to satisfy customer orders. Each vehicle has a fixed capacity, and each order uses a fixed portion of vehicle capacity. The routing decision involves determining which of the demands will be satisfied by each vehicle and what route each vehicle will follow.

The Vehicle Routing Problem (VRP) was introduced 50 years ago by Dantzig and Ramser under the title “The Truck Dispatching Problem.” The study of the VRP has given rise to major developments in the fields of exact algorithms and heuristics. In particular, highly sophisticated exact mathematical programming decomposition algorithms and powerful metaheuristics for the VRP have been put.

Its framework is a smart combination of three simple procedures: the classical k-opt exchanges improve the solution, an ad hoc procedure reduces the number of vehicles and a second objective function.

Abstract This paper presents two new heuristics for the vehicle routing problem on tree-like road networks. These networks occur, for example, in rural road systems where the supply (or delivery) nodes are located on rural roads leading off from a few highways which form the ‘trunks’ of a tree-like by: Journal on Vehicle Routing Algorithms() A comparison of acceptance criteria for the adaptive large neighbourhood search metaheuristic.
Journal of Heuristicsprovides an ov erview of heuristics for the VRP, with an emphasis on recent results. The history of VRP heuristics is as old as the problem itself. In their seminal paper, Dantzig and Ramser. He is author of about papers and book chapters, editor of several journal special issues, and coeditor with Paolo Toth of The Vehicle Routing Problem (SIAM, ).
He was awarded the first prize of FARO competition organized by the Italian Railways in (with Alberto Caprara, Matteo Fischetti, and Paolo Toth) and was a finalist for the.
Several of the Heuristics for vehicle routing over tree-like networks book important classical and modern heuristics for the vehicle routing problem are summarized and compared using four criteria: accuracy. speed, simplicity and flexibility. The vehicle routing problem use heuristics method as their base on solving the distribution model.
Step that are required on building the model are; 1.) simulate the distribution channel by using. The heuristic has also shown promising results for a large class of vehicle routing problems with backhauls as demonstrated in Ropke and Pisinger [A unified heuristic for a large class of vehicle routing problems with backhauls.

Keywords: vehicle routing problem; heuristics Introduction The Vehicle Routing Problem (VRP), introduced by Dantzig and Ramserl inholds a central place in distribution management and has become one of the most widely studied problems in combinatorial optimization.
The Classical VRP can be formally defined as follows. Let G (V,A) be a. The heuristics have the conventional objective of minimising the total distance travelled by the vehicles. The development of the heuristics takes advantage of the tree-like structure of the. Several of the most important classical and modern heuristics for the vehicle routing problem are summarized and compared using four criteria: accuracy, speed, simplicity and flexibility.

Metaheuristics 4. Other Variants of VRP. The vehicle routing problem (VRP) has been very ex- tensively studied in the optimization literature.
It started with the seminal papers of [1,2]. Now, VRP offers a wealth of heuristic and metaheuristic approaches, which are surveyed in the papers of .
The VRP is so widely studied because of its wide applicability and its impor.

The use of networks to describe these problems has the advantage of allowing the decision maker to visualize the prob-lem under consideration. As an example, refer to Figure T Vehicle Routing Problem (VRP) is an area which has been widely dealt with for the last four decades.
Methodologies have been developed for many variants of the VRP. This work considers concurrent and sequential delivery and pick-up in VRPs, encountered in practice but rarely considered in theory.

The paper describes a model for the optimal management of periodic deliveries of a given commodity. The goal is to schedule the deliveries according to feasible combinations of delivery days and to determine the scheduling and routing policies of the vehicles in order to minimize over the planning horizon the maximum number of vehicles simultaneously employed, i.e., the fleet size.
