Modelos matemáticos para problemas de dimensionamento de lotes com restrições de capacidade e custos de transporte

Abstract: Resumo: Neste trabalho estudam-se problemas de dimensionamento de lotes em que as decisões clássicas do dimensionamento dos lotes de produção são tomadas considerando também os custos do transporte dos produtos fabricados. Estes custos estão associados ao número de paletes ou caminhões necessários para empacotar e/ou transportar os produtos produzidos desde a fábrica até o depósito. São consideradas três extensões de um modelo de programação inteira mista, apresentado na literatura, representando casos mais ge… Show more

“…Molina et al (2009) proposed a heuristic method to solve the problem presented in Norden and Velde (2005) and proposed an extension of the model by taking into account the delay in delivery of demand and production capacity constraints. In Molina et al (2013), other extensions of the models originally proposed in Norden and Velde (2005) and Molina et al (2009) representing more general cases, that occur in practice, were analysed and, also, a solution method based on Lagrangian relaxation was implemented for one of the proposed extensions. In the present paper, we further extend the models from the literature mainly by considering the combination of the production lot sizing decisions and truck loading decisions without intermediate cargo unitization devices such as pallets and containers.…”

“…They should consider the influence of production factors, the costs related to the latters and how these costs can influence the PPC. The works that address only the lot sizing problem can be seen in Brahimi et al (2006) and Molina et al (2013).…”
