2L-CVRP: A GRASP resolution scheme based on RCPSP

2009 International Conference on Computers & Industrial Engineering, 2009
This paper addresses an extension of the well-known Capacitated Vehicle Routing Problem (CVRP) where the customer demands represented by two-dimensional weighted items have to be packed into the vehicles. This problem, denoted 2L-CVRP, is NP-hard and it is particularly difficult to solve in practice.

Common grounding optimization for CVRP

2013 IEEE 8th Conference on Industrial Electronics and Applications (ICIEA), 2013
In this paper, a new evolutionary algorithm called common grounding optimization (CGO) is proposed for capacitated vehicle routing problem (CVRP). The algorithm consists of three main operations: common ground seeking, encapsulating, and iterated local search (ILS). The algorithm is population-based with all the individual solutions eventually converge

Implementation of SUMO Simulation for Comparison of CVRP

2021 International Electronics Symposium (IES), 2021
With the rapid increase in human density, development, and mobility in urban areas, the need for logistics distribution systems is increasing which is an important part of connecting industries with their consumers. Thus, route planning is an important thing for the industry.

Stable solving of CVRPs using hyperheuristics

Proceedings of the 11th Annual conference on Genetic and evolutionary computation, 2009
In this paper we present a hill-climbing based hyperheuristic which is able to solve instances of the capacitated vehicle routing problem. The hyperheuristic manages a sequence of constructive-perturbative pairs of low-level heuristics which are applied sequentially in order to construct and improve partial solutions.

Bacterial Resistance Algorithm. An Application to CVRP

2019
This work considers an approach called Bacterial Antibiotic Resistance Algorithm (BARA) in which a bacteria colony represents a set of candidates solutions subjected to the presence of an antibiotic as a pressure factor for separating good and wrong answers.

Lösung von CVRP mittels naturanaloger Verfahren

1995
Um allgemeinere Tourenplanungsprobleme wie das Capacitated Vehicle Routing Problem (CVRP) fur genetische Algorithmen zuganglich zu machen, stellen sich abermals alle im Rahmen des TSP beantworteten Fragen zu Problemreprasentation, Mutations- und Crossover- Operatoren.
