    Metaheuristics applied to vehicle routing. A case study. Part 1: formulating the problem
    (National University of Colombia, 2006) Guillermo Vargas; Felipe González Aristizábal
    This paper deals with VRP (vehicle routing problem) mathematical formulation and presents some methodologies used by different authors to solve VRP variation. This paper is presented as the springboard for introducing future papers about a manufacturing company’s location decisions based on the total distance traveled to distribute its product.

    Metaheuristics applied to vehicle routing. A case study. Part 2: genetic algorithm, compared to a heuristics solution
    (National University of Colombia, 2007) Guillermo Vargas; Felipe González Aristizábal
    This paper presents a solution to a vehicle-routing problem by using two different techniques. In the first instance, a genetic algorithm was applied (different experiments were done); later on the cluster first-route second methodology was used via heuristic sweep and local search, respectively. The results of the different techniques were then compared.
