Abstract

O planejamento operacional de um sistema de transporte de cargas de longa distância implica resolver um problema de otimização de rede dinâmica capacitada, visando a efetuar de forma eficaz e eficiente os movimentos das cargas, utilizando os recursos de transporte disponíveis. O presente trabalho aborda a utilização de programação dinâmica aproximada e adaptativa para solução desse tipo de problema. A metodologia de solução proposta substitui o processo de otimização global da rede por um modelo de Programação Dinâmica aplicado a cada estágio do problema; o método baseia-se em uma heurística para estimar o valor que a solução de cada estágio transfere para os estágios subseqüentes. A técnica utilizada reduz sensivelmente a quantidade de variáveis envolvidas, o que viabiliza a construção de modelos matemáticos mais realistas em um horizonte de planejamento mais amplo. São apresentados resultados de uma aplicação bem sucedida do modelo com utilização do Jensen Network Solver.
