Abstract(s)
Associada ao crescimento populacional e ao aumento da esperança média de vida, é expectável que as necessidades energéticas da humanidade continuem a aumentar no curto/médio prazo. Neste contexto, a exploração e otimização de um setor como o dos Gases de Petróleo Liquefeito (doravante designado por setor do GPL, ou simplesmente pelo acrónimo GPL), afetado por constantes mudanças, quer provenientes da permanente evolução tecnológica, quer da descoberta de novas localizações de petróleo, mantém um caráter de especial importância nos dias que correm.
O presente estudo de investigação visa aprofundar os conhecimentos adquiridos ao longo do mestrado em Decisão Económica e Empresarial, nomeadamente na área da Investigação Operacional, aleado ao tema do GPL enquadrado na empresa portuguesa Galp Energia.
Após o tratamento dos dados e resolução do problema real, chegou-se à conclusão de que a distância total percorrida em 85 dias de trabalho, durante os meses de janeiro, fevereiro e março, foi superior à da situação modelada e correspondente otimização de rotas, o que resultaria numa poupança dos custos totais de aproximadamente 10%, se a Galp Energia aplicasse o método proposto. Este tema será abordado ao longo do projeto e compreender-se-á melhor o enquadramento destes resultados e os pressupostos que tiveram que ser tomados.
Note-se que, apesar da simplificação ao problema, o presente projeto mostra o quão importante se torna investir num bom programa de otimização de rotas, uma vez que mesmo simplificado, a resolução do problema proporcionaria importantes melhorias em termos de custos para a Galp Energia.
Associated with population growth and increased life expectancy, it is expected that the human energy needs will continue to increase in the short / medium term. In this context, the operation and optimization of a sector such as Liquefied Petroleum Gas (LPG), although conditioned by several changes, either in the ongoing technological evolution or in the new oil discovery locations, maintains a particularly important character nowadays. This research study aims to expand the knowledge acquired in the context of the Master's degree in Economic and Business Decision, in particular in the area of Operational Research, associated to the LPG theme framed in the Portuguese company Galp Energia. After solving the proposed problem, the conclusion is that the total distance traveled in 85 working days, between January and March, was higher than the one modeled and optimized. The proposed method would lead to a 10% save of the total cost for Galp Energia. This issue will be addressed throughout the project, and both the framework of present results and the assumptions that were made will be better understood. It is important to note that, despite the simplification of the problem, this project shows how important it is to invest in a good optimization program, since even a simplified solution to the problem would provide significant benefits in terms of costs for Galp Energia.
