Distributed Decision Making in Combined Vehicle Routing and Break Scheduling [PDF]

open access: yes, 2009
The problem of combined vehicle routing and break scheduling comprises three subproblems: clustering of customer requests, routing of vehicles, and break scheduling.

Optimal Routing of Energy-aware Vehicles in Networks with Inhomogeneous Charging Nodes

open access: yes, 2014
We study the routing problem for vehicles with limited energy through a network of inhomogeneous charging nodes. This is substantially more complicated than the homogeneous node case studied in [1]. We seek to minimize the total elapsed time for vehicles

Different versions of the savings method for the time limited vehicle routing problem

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2012
The time limited vehicle routing problem (TLVRP) stems from the vehicle routing problem. The main difference is that the routes are paths (not cycles), i.e. vehicles do not return to the central city (or at least we do not observe their way back).

On a Labeled Vehicle Routing Problem [PDF]

open access: yes, 2010
In this paper, we study the complexity and (in)approximability of the minimum label vehicle routing problem. Given a simple complete graph G = (V,E) containing a special vertex 0 called the depot and where the edges are colored (labeled), the minimum label k-vehicle routing problem consists in finding a k-vehicle routing E?, i.e. a collection of cycles

Analyzing combined vehicle routing and break scheduling from a distributed decision making perspective [PDF]

open access: yes, 2009
We analyze the problem of combined vehicle routing and break scheduling from a distributed decision making perspective. The problem of combined vehicle routing and break scheduling can be defined as the problem of finding vehicle routes to serve a set of

AASA: A Priori Adaptive Splitting Algorithm for the Split Delivery Vehicle Routing Problem

open access: yesAlgorithms
The split delivery vehicle routing problem (SDVRP) is a relaxed variant of the capacitated vehicle routing problem (CVRP) where the restriction that each customer is visited precisely once is removed.

Optimizing departure times in vehicle routes [PDF]

open access: yes, 2007
Most solution methods for the vehicle routing problem with time\ud windows (VRPTW) develop routes from the earliest feasible departure time. However, in practice, temporal traffic congestions make\ud that such solutions are not optimal with respect to ...

Hybridizing large neighborhood search and exact methods for generalized vehicle routing problems with time windows

open access: yesEURO Journal on Transportation and Logistics, 2021
Delivery options are at the heart of the generalized vehicle routing problem with time windows (GVRPTW) allowing that customer requests are shipped to alternative delivery locations which can also have different time windows.
