Previous issue date: 2011-07-13 / Conselho Nacional de Desenvolvimento Cient?fico e Tecnol?gico / This paper aims to propose a hybrid meta-heuristics for the Heterogeneous Fleet Vehicle Routing Problem (HVRP), which is a combinatorial optimization problem NP-hard, and is characterized by the use of a limited fleet consists of different vehicles with different capacities. The hybrid method developed makes use of a memetic algorithm associated with the component optimizer Vocabulary Building. The resulting hybrid meta-heuristic was implemented in the programming language C + + and computational experiments generated good results in relation to meta-heuristic applied in isolation, proving the efficiency of the proposed method. / O presente trabalho visa propor uma meta-heur?stica h?brida para o Problema de Roteamento de Ve?culos com Frotas Heterog?neas (PRVFH), que ? um problema de otimiza??o combinat?ria NP-dif?cil, e que se caracteriza pelo uso de uma frota limitada composta por ve?culos distintos com capacidades distintas. O m?todo h?brido desenvolvido utiliza-se de um algoritmo mem?tico associado ao componente otimizador Vocabulary Building. A meta-heur?stica h?brida resultante foi implementada na linguagem de programa??o C++ e os experimentos computacionais geraram bons resultados em rela??o ? meta-heur?stica aplicada isoladamente, comprovando a efici?ncia do m?todo proposto.
