    Avaliação do grau de exclusão social relacionada ao transporte aquaviário através do método de Necessidades Socialmente Percebidas (NSP): o caso de Cotijuba
    (Universidade Federal do Pará, 2022-06-10) SOARES, Rodolpho Pinto; ROCHA, Marcus Pinto da Costa da; http://lattes.cnpq.br/7169569605967930; https://orcid.org/0000-0002-1849-1982; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394; https://orcid.org/0000-0003-0214-0587
    Social exclusion related to transportation in areas of vulnerability causes the marginalization of people residing in that region due to the impossibility of providing them with access to employment, health, education, leisure and other services essential to the individual's full participation in society. The city of Belém, both in the continental region and on the islands, presents a panorama where public urban transport is close to its operational limit, leaving something to be desired in the service of peripheral areas, causing the population living there to face daily problems to circulate and, even more, being imputed in its reach to such services and opportunities. This work aims to assess the degree of social exclusion related to transportation in areas of vulnerability as a subsidy for public policy guidelines. The methodology can be divided into two parts, the first of a qualitative nature, is a bibliographic review, through secondary sources to bring the theoretical basis of the work. The second part, of a quantitative nature, will be based on the Socially Perceived Necessities method, originating from the social sciences, which consists of drawing up a list of items, here, it was adapted from the lists of other countries, that are considered essential for the individual to live with quality of life, the application of the method, through interviews in the regions of vulnerability, in this case, the island of Cotijuba, and the analysis of the results, using the computer programs Microsoft Excel and Microsoft Power BI. Then, it was possible to determine the degree of social exclusion related to transport in three dimensions: Work, Education and Health, identify critical points and propose public policy guidelines aimed at mitigating the scenario for the island's population.

    Formação de comboios fluviais para o trnsporte de grãos a partir de parâmetros de segurança e economia
    (Universidade Federal do Pará, 2022-09-26) SILVA, Breno Farias da; ROCHA, Marcus Pinto da Costa da; http://lattes.cnpq.br/7169569605967930; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394
    The transport of grains in the Amazon region is carried out by waterways and highways, however, there are problems of congestion in the accesses and productivity of the ports that is still low. In the last decades the Brazilian bulk production has been experiencing a great growth, the search for better logistical solutions in the scope of the production flow in the shortest time and at the lowest cost, has brought a prominent role to the Amazon region. As the largest watershed in the world, its waterways have become one of the most important axes for all national production. Notwithstanding the forecast of increased production, it has become essential to develop strategic methods to ensure its viability and optimization, in this way, the main companies operating in this market already use river convoy models for flow. In the competitive scenario, ways and means were developed to improve its transport logistics, employing sufficient measures to optimize the entire process. It is known that the agricultural bulk process by push convoys is carried out by river barges. These projects were developed in a different navigation and demand scenario. In search of a more adequate solution, with the conditions of the Amazonian navigation environment and the high capacities necessary for the bulk carrier convoys, this work has the fundamental scope to elaborate on model in the fluvial convoy formation that could analyze the additional cost for convoys over 210 m, which intend to navigate in the Estreito de Breves-PA, using the possible formations that would generate a better economic viability of the fluvial convoys used in the Amazon, being the model presented in this dissertation of great importance for optimization for the formation of the convoys of push, since it could obtain the cost per ton for each formation due to the normative requirements for navigation in the region of the straits of the island of Marajó with the following results: extra pushers for convoys of 35 and 45 barges and auxiliary pushers (scouts) for the formations of 25, 35 and 45 barges, generating highly positive aspects s in the commercial scope for large companies that use this type of service.

    Impacto da regulação na atividade de transporte fluvial misto
    (Universidade Federal do Pará, 2018-05-11) ARRUDA, Augusto Rolim Dias; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394; https://orcid.org/0000-0003-0214-0587
    The present dissertation analyzed the development of mixed river transport (cargo and passengers) in the Amazon River region (lines Belém-PA to Manaus-AM and Belém-PA to Macapá / Santana-AP), in the period from 2011 to 2016, in order to identify the evolution of the quality of river transport services practiced, due to the performance of the State regulation. The evolution of regulation, the particularities of service provision and its impact on society, as well as the effectiveness of the regulatory tools on the quality of service provided by the companies authorized by the regulatory body, are evaluated by effective penalties, with information obtained by the Union's official press, analyzing its practical and statistical connotations. The "Analytic Hierarchy Process - AHP" was used to evaluate the aspects that most impact on the provision of services to users of inland waterway passenger transportation in Amazonian lines, being the criteria and weights used from Antaq research and published article. In this respect, it was observed that the supervision procedure aims to assess all the obligations imposed by the regulatory standard in an isonomic manner, without any connection with the user's wishes and that the monetary values of the penalties are defined on a technical basis, in line with the various obligations required for the execution of the transport service. Also, a statistical analysis was carried out on the possibility of linking operational and monetary aspects of those authorized companies with the application of penalties by the regulatory agency. It was concluded that the amount of infractions depends on the action of the service provider and the methodology used in the inspection action, and with the publicly available information, there is no statistical evidence that identifies the factors involved, including lack of public access to the criteria adopted each year by the regulatory body in its planning, as well as the commitment adopted by it, whether related to the application of monetary resources or personnel.

    Otimização do processo de embarque de navios de grãos utilizando modelo de simulação: estudo de caso no complexo portuário do Itaqui
    (Universidade Federal do Pará, 2023-10-20) OLIVEIRA FILHO, Landrin Sandin Gonçalves de; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394; https://orcid.org/0000-0003-0214-0587
    The port of Itaqui, Maranhão/Brazil, consolidated its prominent position in the northern arc, being the only one to move grains in quantities above its potential, estimated to export around 12 million tons in 2020 and closed the year with 12, 1 million tons of grain moved. The growth in exports occurred with the consolidation of the 2nd phase of the Itaqui Port Grain Terminal - Tegram, added to the investments made in the expansion, with the adoption of measures to improve operationalization, with the optimization of access, the dredging of berths and access channels, providing an increase in the capacity to move 20 million tons in 2025. The present work proposes to choose the scenario among the simulated models, which presents the best results in grain ship loading operations, with the application of stochastic processes through modeling and simulation techniques using specialized software, which provides optimization of the productive capacity of the port of Itaqui. The Arena software was used to develop the model and, through two alternative scenarios, analyzes were carried out in relation to waiting times at anchorage, number of ships served and occupancy rate.

    Otimização e análise de risco da capacidade portuária da bacia amazônica, quanto ao crescimento da demanda de grãos e ao porte dos navios
    (Universidade Federal do Pará, 2022-06-03) MORAES NETO, Luciano Pinto de; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394; https://orcid.org/0000-0003-0214-0587
    Maritime transport in recent years has brought about a great change in ports around the world due to the advancement of technology which allowed the construction of increasingly larger vessels to reduce freight and transport more cargo. Aware of this reality, this work develops an assessment of port terminals in the Amazon basin, using queuing theory combined with risk analysis and optimization to evaluate port capacity in the face of future grain demands for the region, given that with the advance technology, larger ships are being manufactured and capable of transporting large amounts of cargo, with this advance, the existing ports need to adapt their infrastructure according to the new trends in shipbuilding. In this dissertation, data was collected of movement of cargo and capacity of the existing port terminals in the Amazon region with a focus on long-haul export terminals. A model was developed using the queuing theory to gauge the capacity of terminals and the productivity of ships for use in the @RISK platform, which uses optimization combined with risk analysis, generating distribution and tornado graphs, enabling the analysis of the terminals. help in decision-making on the performance of terminals and ships in an integrated manner. The research allows, through generated simulations, the analysis of various scenarios for the movement of grain from these terminals and the impact that larger ships will bring to the region's port infrastructure. Considering that the estimated movement of terminals in the Amazon basin for 2030 is approximately 60 million tons, where it was observed that the terminals are not prepared to achieve this stipulated target if they do not invest in their development.
