  • Universidade de São Paulo
    Master of Science (M.Sc, Logistics and maritime transport

    Jan 2017 - Dec 2021 (5 years)
    This dissertation tackles the Periodic Location-Routing Problem (PLRP), where depots are located and delivery routes planned across multiple periods to serve customers with varying service frequencies. A simulated annealing (SA) algorithm is proposed, taking advantage of parallel computing power, to achieve efficient solutions. Unlike existing approaches, customers are assigned fixed depots. Initial solutions are generated through a relaxed MIP model and a heuristic, further refining via SA. Testing against benchmark instances confirms the effectiveness of the proposed method. Key points: - PLRP combines facility location and vehicle routing with periodic service. - SA algorithm with parallel computing for efficient optimization. - Fixed cu

      Auto-estradas do mar: um paradigma viável para o Brasil?
      CONGRESSO PANAMERICANO DE ENGENHARIA NAVAL
      Jan 2011
      Nos últimos anos é notório o crescimento econômico do Brasil, inclusive com planos de desenvolvimento social e sustentável. Contudo, no que diz respeito aos transportes, os planos de investimentos tem-se desenvolvido lentamente, mesmo sendo comprovado a contribuição destes na redução dos gargalos logísticos do país. Os investimentos do setor público, por exemplo, na infraestrutura de transportes do Brasil, têm sido muito pequenos comparados com outros países. Estudos e projetos realizados em países da União Européia desenvolveram o conceito de “Autoestradas do Mar - MoS”. Embora o Brasil seja um país ainda com pequeno uso de intermodalidade, a adaptação desse conceito europeu, que visa à introdução de novas cadeias logísticas intermodais e
