A presente dissertação foi realizada na empresa TELEF – Transportes por Cabo e Concessões, S.A., onde se procurou desenvolver um modelo de apoio à decisão relativo à implementação de um sistema de transporte por cabo usando a simulação discreta. Para tal utilizou-se o software de simulação ARENA, considerando vários cenários hipotéticos. O modelo foi validado com dados recolhidos do Teleférico de Gaia e do Teleférico do Funchal. A ferramenta de apoio à decisão resultante permite o estudo do sistema de transporte com vista à identificação da solução mais eficaz e eficiente, com base no ajuste de parâmetros numa interface gráfica desenvolvida para o efeito e na animação do modelo. No âmbito do estudo desenvolvido foram realizadas simulações com o objetivo de analisar o impacto de: (i) variações no número de passageiros a transportar; (ii) variações de capacidade ao nível do número de veículos a incluir no sistema de transporte por cabo; e de (iii) limites ao número de passageiros a embarcar como forma de gerir as filas de espera nas estações intermédias do teleférico. Foi ainda considerado um exemplo prático de transporte por cabo com estação intermédia, com vista à identificação de cenários para melhorar a eficiência e eficácia de um transporte de passageiros neste âmbito. A ferramenta de apoio à decisão desenvolvida reveste-se de uma forte relevância prática, permitindo avaliar o impacto de diferentes parâmetros do sistema de transporte por cabo, contribuindo desta forma para a fundamentação da decisão sobre: (i) a configuração a utilizar em sistemas novos; e (ii) a necessidade de alterar sistemas existentes.
The present dissertation was carried out at TELEF - Transportes por Cabo e Concessões, S.A., where were tried to develop a decision support model for the implementation of a cable car transportation using the discrete simulation. For that the ARENA simulation software was used, considering several hypothetical scenarios. The model validation was performed with data collected from Gaia Cable Car and Funchal Cable Car. The resulting decision support tool allows the study of the transport system to identify the most effective and efficient solution, based on parameter setting in a graphical interface developed for the purpose and the animation of the model. In the scope of this study, simulations were performed to analyse the impact of: (i) variations in the number of passengers to be transported; (ii) capacity variations in the number of vehicles to be included in the cable transport system; and (iii) limits to the number of passengers to board as a means of managing queues at cable car intermediate stations. It has also been considered a practical example of a cable car transport with a middle station to identify scenarios for improving the efficiency and effectiveness of passenger transport in this system. The decision support tool developed has a strong practical relevance, allowing to evaluate the impact of different parameters of the cable transport system, contributing this way to substantiate of the decision on: (i) the configuration to be used in new systems; and (ii) the need to change existing systems.
