Evolutionary Algorithms for Capacitated Arc Routing problems with Time Windows
The Capacitated Arc Routing Problem (CARP) involves vehicles routing, serving a set of arcs in a network. This NP hard problem is extended to take into account time windows, entailing a new and hard theoretical model in arc routing called the CARPTW (CARP with time windows). The CARPTW is useful for modeling urban waste collection or winter gritting. This paper presents this new model and a mem...
متن کاملEvolutionary Algorithms for Multiperiod Arc Routing Problems
The Capacitated Arc Routing Problem (CARP) is useful for modeling urban waste collection or winter gritting, at the operational decision level. Many applications require a tactical version, the periodic CARP (PCARP), in which the trips are planned over a multiperiod horizon, subject to frequency constraints. The paper presents this new and hard theoretical problem, its variants, and a powerful ...
متن کاملApproximation Algorithms for Mixed, Windy, and Capacitated Arc Routing Problems
We show that any α(n)-approximation algorithm for the n-vertex metric asymmetric Traveling Salesperson problem yields O(α(C))-approximation algorithms for various mixed, windy, and capacitated arc routing problems. Herein, C is the number of weakly-connected components in the subgraph induced by the positive-demand arcs, a number that can be expected to be small in applications. In conjunction ...
متن کاملEvolutionary Approach for Energy Minimizing Vehicle Routing Problem with Time Windows and Customers’ Priority
A new model and solution for the energy minimizing vehicle routing problem with time windows (EVRPTW) and customers’ priority is presented in this paper. In this paper unlike prior attempts to minimize cost by minimizing overall traveling distance, the model also incorporates energy minimizing which meets the latest requirements of green logistics. This paper includes the vehicles load as an ad...
متن کاملExact Algorithms for Electric Vehicle-Routing Problems with Time Windows
Effective route planning for battery electric commercial vehicle (ECV) fleets has to take into account their limited autonomy and the possibility of visiting recharging stations during the course of a route. In this paper, we consider four variants of the electric vehicle-routing problem with time windows: (i) at most a single recharge per route is allowed, and batteries are fully recharged on ...
