The vehicle routing problem with time windows and multiple deliverymen (VRPTWMD) is a variant of the vehicle routing problem with time windows in which service times at customers depend on the number of deliverymen assigned to the route that serves them. In particular, a larger number of deliverymen in a route leads to shorter service times. @article{osti_, title = {New heuristics for traveling salesman and vehicle routing problems with time windows}, author = {Gendreau, M and Hertz, A and Laporte, G and Mihnea, S}, abstractNote = {We consider variants of the Traveling Salesman (TSP) and Vehicle Routing (VRP) Problems in which each customer can only be visited within a pre-specified (hard) time .

Introduction. The main concern of distribution management is to design the optimal vehicle routes for customer service. The classic vehicle routing problem (VRP) is to determine a set of routes that minimizes total travel time or distance, originating and terminating at a central depot, for a fleet of vehicles which services a set of customers with known demands or by: This article is a survey of heuristics for the Vehicle Routing Problem.

The Vehicle Routing Problem with Time Windows is a particular case of the classical Vehicle Routing Problem in which the demands of each customer should be met within an established time window.

Due to the combinatorial complexity of the problem its resolution by pure exact methods is, in many cases, computationally impractical. This fact. The aim of this paper is to propose a new heuristic for the Periodic Vehicle Routing Problem (PVRP) without time windows.

The PVRP extends the classical Vehicle Routing Problem to a planning horizon of several days. Each customer requires a certain number of visits within this time horizon while there is some °exibility on the exact days of.

The most famous local search moves are 2-Opt and 3-Opt related to edge-exchange neighborhoods for a single route. The 2-Opt method was proposed by Flood in and Croes in and is based on deleting two edges from the same route followed by reconnecting the subtours in the other way.
