Item Acesso aberto (Open Access) Preposição de um instrumento para avaliação dos terminais hidroviários de passageiros: estudo de caso no estado do Pará(Universidade Federal do Pará, 2023-11-30) GARCIA JUNIOR, Guiler Oliveira; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394; https://orcid.org/0000-0003-0214-0587; SAID, Mounsif; http://lattes.cnpq.br/8493361134195157; https://orcid.org/0000-0003-0656-6841River transport is the most important means of transport for delivering people and cargo in the State of Pará, and is responsible for promoting the population's quality of life. The region's waterway terminals have very rudimentary logistical planning in terms of their operational dynamics. This brings a lot of inconvenience to those who use the means of transport to travel. The specific purpose of this work was to develop an instrument for evaluating the quality of services offered in passenger terminals in the municipalities of Belém and Salvaterra, in Marajó. Through observational methodology, through the application of evaluative questionnaires from the National Waterway Transport Agency (ANTAQ) and a Survey survey. It was confirmed that the waterway terminals are not operating efficiently and that the factors found, such as lack of security, policing, accessibility, inadequate parking, untrained employees, among others, make operations at port facilities difficult. The results allowed the identification of problems in user access and circulation at waterway terminals, in addition to providing improvements in their infrastructure, accessibility and mobility, directly impacting passengers' quality of life.Item Acesso aberto (Open Access) Avaliação do desempenho portuário do porto de Santana no contexto do projeto arco norte através da análise hierárquica de processo - AHP(Universidade Federal do Pará, 2024-12-07) SILVA, Álisson Sousa da; TOBIAS, Maisa Sales Gama; http://lattes.cnpq.br/9635266655242384; https://orcid.org/0000-0002-0888-0685Brazil has significant agricultural production, the flow of which represents a logistical and operational challenge due to restrictions and limitations of transport infrastructure. The assessment of port performance is an issue to be observed, in particular, in the North region, with enormous hydrographic potential for navigation and economic importance, and proposals for logistical solutions for the more efficient flow of agricultural production. Special emphasis is placed on agricultural production coming from the Center-West, with grain transport routes leaving this region, partly to the states of Pará and Amapá and, via the Madeira River Waterway, through the State of Amazonas. From this perspective, the Arco Norte project emerged at the beginning of the 2010s, proposing the formation of an intermodal network, taking advantage of existing transport infrastructures and also new investments, based on production estimates for grain exports from the State of Mato Grosso in particular, soy. Among the ports considered, the Port of Santana - AP stands out for its proximity to the sea and soybean destinations, available area for expansion and low current occupancy rate. In view of the above, this work presents research of a documentary and data nature, with the objective of evaluating the criteria that influence the performance of the Port of Santana within the scope of the Arco Norte project, promoting a hierarchical process analysis of its priorities in the composition of the efficient intermodal regional transport network at the port, in light of demand expectations and future expectations. To this end, the methodology was based on a bibliographical review of studies on Arco Norte and, also, on-site visits to port stakeholders, to select the criteria for the Port of Santana. With the criteria in hand, a questionnaire was applied to support the application of the Hierarchical Process Analysis (AHP) method, involving stakeholders linked to the port, for the hierarchization as a response to the evaluation criteria of the Port of Santana and its critical aspects. In the results obtained from this dissertation, there is a prior selection of criteria, based on existing literature and empirically validated with stakeholders. Also, the proposition and use of an instrument (questionnaire) to identify and classify port assessment criteria, using the AHP method. At the end of the dissertation, the order of priority of the criteria and alternatives and the relationship between them were established, as well as a recommendation for the investments necessary to accredit the Port of Santana in the Arco Norte project, highlighting the pressing need to expand the pier to enable the attraction of long-haul vessels. Furthermore, improving land access, together with the opening of new expansion areas, is a priority for improving operations. The administrative integration of institutions in the port system also stood out as a strategic element. In this context, the alternatives highlighted, such as the optimization of port movement, investment in dredging and the introduction of technology, emerged as fundamental responses to meeting defined demands, promoting efficiency, competitiveness and preparation for future challenges.Item Acesso aberto (Open Access) 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/0000-0003-0214-0587The 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.Item Acesso aberto (Open Access) Rede neural convolucional (cnn) aplicada na análise de risco de acidentes das embarcacões que navegam nos rios da Amazônia(Universidade Federal do Pará, 2022-11-18) NASCIMENTO, Ariel Victor do; FARIAS, Valcir João Farias da Cunha; http://lattes.cnpq.br/4958123373113545; https://orcid.org/0000-0002-2564-2195; ROCHA, Marcus Pinto da Costa da; http://lattes.cnpq.br/7169569605967930; https://orcid.org/0000-0002-1849-1982Navigation safety is an important issue to maintain the well-being and integrity of passengers and cargo. There are many rules to follow to assess safety, certifiers and classifiers are responsible for ensuring compliance with all these rules that ensure the integrity of vessels, however, this is not enough. The Administrative Inquiry of Naval Accidents and Facts (IAFN), a document prepared by the Brazilian Navy, collects information and creates a database to show how many accidents occur in Brazil by region, which are defined as Naval Districts (DN). The 4th Naval District, in which the state of Par´a is located, was the first in accidents that occurred in 2020 and the third in 2021. Due to these accidents, concepts of artificial intelligence, machine learning and deep learning were used. applied in this area. In order to assist in this process, this work proposes to develop an application using Convolutional Neural Network (CNN) for image recognition (Vessels and Disc of plimsoll). In this sense, a Convolutional Neural Network (CNN) learning technique was used, which allows identifying the type of vessel through a bank of images provided, the same method was applied to identify if there is a risk of accident with the vessel through analysis of disk images of plimsoll. To carry out the training of the CNNs, six different network architectures were evaluated with: changing the number of filters in each convolutional layer; variation in the amount of convolutional layers and; use of transfer of learning from the VGG-16 network with the fine-tuning technique. The results achieved in this work are promising and demonstrate the feasibility of using the Convolutional Neural Network as a method for identifying the images of vessels as the disk of plimsoll).Item Acesso aberto (Open Access) Análise numérica das distorções em soldas de topo do aço estrutural naval via elementos finitos(Universidade Federal do Pará, 2024-12-12) MOTA, João Epifânio da; LAMEIRA, Pedro Igor Dias; http://lattes.cnpq.br/5391645898597252; https://orcid.org/0000-0001-8038-8276In this research, one of the alternatives for evaluating welding distortions was to use computer simulation. A numerical analysis was then developed to determine the transverse distortion field in welded joints. The numerical simulations were carried out using commercial software, ANSYS Workbench, based on the Finite Element Method (FEM). Input parameters were entered, such as: current, voltage, welding speed and initial temperature of the virtual plate. The simulations used a virtual ASTM A36 steel plate welded using the Flux-Cored Arc Welding (FCAW) process. The influence of the geometry of the “V” and “U” bevel types on the thermal efficiency of welding, restrictions on plate distortions and heat input were verified. Although these initial simulations are qualitatively comparative, they have been validated on the basis of results from the literature, i.e. they are of quantitative importance. However, only specific results were verified that presented possibilities for combining butt joints and heat sources in structural steel. It was therefore essential to establish a sequential analysis method for adjusting the model, which would provide the main characteristics of a welding process (heat source, joint geometry, the thermodependent properties of A36 steel). The results of the analysis showed good approximation and agreement with the literature analyzed for both the temperature and deformation fields.Item Acesso aberto (Open Access) Programação Linear aplicada no Transporte Aquaviário de passageiros sob restrições de demanda e nível de serviço para as travessias Belém-Camará, Belém-Arapari e Belém-Cotijuba(Universidade Federal do Pará, 2022-12-22) ALENCAR, Elisangela da Silva dos Santos de; ROCHA, Marcus Pinto da Costa da; http://lattes.cnpq.br/7169569605967930; https://orcid.org/0000-0002-1849-1982; TOBIAS, Maisa Sales Gama; http://lattes.cnpq.br/9635266655242384; https://orcid.org/0000-0002-0888-0685In the Amazon region, hydrological transportation has historically played a crucial role. However, passenger water transportation lacks economic models that assist in the design and implementation of strategies for its viability. In this study, a cost model for passenger water transportation was developed based on activity-based costing principles and linear programming. The aim was to optimize costs and maximize profits, considering demand and service level constraints in a water transportation company in the city of Belém, Brazil. The model was applied to three crossings that operate passenger, cargo, and vehicle trips between Belém and Ilha de Marajó. Various simulations were conducted to explore opportunities and conditions for reducing operational costs. The objective was to find the best cost-profit relationship, with the model parameters including variable costs, profits, and the maximum number of possible trips. Based on the results, alternative cost reduction strategies were established to achieve maximum profit and the highest number of trips. The model proved to be useful through the analysis of viable and effective cost reduction strategiesItem Acesso aberto (Open Access) Avaliação da eficiência operacional de terminais hidroviários de passageiros aplicando análise envoltória de dados: um estudo de caso na região de integração do baixo amazonas(Universidade Federal do Pará, 2024-01-12) PINA, Anna Júlia Sousa de; FARIAS, João Valcir Cunha; http://lattes.cnpq.br/4958123373113545; https://orcid.org/0000-0002-2564-2195National port development is directly related to the efficiency of the international commercial links that the country establishes, as well as to international commercial relations, which depends on the capacity to use the existing waterway network in the national territory, the use of which is currently resumed at 30% of its waterway potential. Therefore, in recent years, investments have been made in the area of river transport, focusing on states with the highest concentration of rivers. As river ports begin to gain strength in favor of logistical dynamization, there is a need to evaluate their efficiency to investigate the relationship between criteria such as location, berthing capacity, waterway flow. Based on this, this research aims to analyze the efficiency of 10 Waterway Terminals in the Lower Amazon region, opened between 2021 and 2022, for which Data Envelopment Analysis was applied (DEA). Variations in results for the terminals considered will be elucidated, making it possible to evaluate port efficiency using a method and relate how it is capable of meeting logistical demands and river traffic in the region, but also to investigate the different results obtained and how these are relate to the characteristics of the terminals in question. We also sought to demonstrate the importance of studies like this to understand the impact caused by waterway terminals, going beyond the economic scope and influencing the growth of regions by providing quality connections between municipalities that primarily depend on river transport, mainly in cities hub such as the municipality of Santarém. Finally, it was identified that four of the ten waterway terminals analyzed are operating at maximum efficiency. These terminals have demonstrated the ability to effectively convert their resources.Item Acesso aberto (Open Access) Análise de viabilidade de implantação de um centro de integração logística na região amazônica: um estudo de caso no Estado do Pará(Universidade Federal do Pará, 2023-03-30) HAGE NETO, Demétrio Dib; MORAES, Hito Braga de; http://lattes.cnpq.br/5044859479302394The celebrated and constant evolution of operating operations and market companies compensate for the integration of process participants and the need to promote new operating strategies, as well as the integration of process participants, as well as the need for integration of participants in the process. process. resources involved in the supply chain. from this scenario of need for evolution and modification of market relations, the use and implementation of outstanding projects of logistics integration centers as a way of improving the logistics reality. Corroborating this reality, the main objective of this research was to verify the feasibility and benefits generated from the implementation of a Logistics Integration Center in the State of Pará - CILOG, from the perspective of the demand for production flow, availability of modal and location. To verify the feasibility of production for implementation, foam consulted without data regarding load states and load locations in adjacent areas, as well as potential, functionalities and resources of the implementation systems, with flow as the main centers of selection and, systematic and systematic way, of the feasibility and evaluation of the benefits generated from the implementation of the needs of the demand for services of attendance of the neighboring states, as well as of the entrances for the attendance of the neighboring states demand of flow of the production, availability of modals and geographic location . For this, an A-SWOT hybrid methodology was applied to define the HP location criteria and the decision factors that characterize the implementation of logistics such as the Logistics Integration Center (CILOG) in the Amazon Region, as well as the definition of the best for this implementation. , based on three local alternatives: Santarém (on the banks of the Amazon River), Alça Viária (on the banks of the Guamá River) and Miritituba (on the banks of the Tapajós River).Item Acesso aberto (Open Access) Análise de alternativas intermodais para escoar a produção de soja dos Estados do Pará e Tocantins(Universidade Federal do Pará, 2021-08-31) OLIVEIRA, Vitor Hugo Pereira de; ROCHA, Marcus Pinto da Costa da; http://lattes.cnpq.br/7169569605967930; TOBIAS, Maisa Sales Gama; http://lattes.cnpq.br/9635266655242384World projections indicate an increase in demand for soy and, in this context, countries with continental dimensions and favorable soils such as Brazil stand out. Particularly, the states of the northern region of Brazil show themselves as possible new agricultural frontiers for this crop. However, they need to be competitive in order to sell their production, which indicates the need for studies of available modal alternatives to determine those with better economic results. With this in mind, the present work executed the analysis of alternative intermodal routes using linear programming, to identify the optimal solution route, in support to decision-making in the transport of soybeans for export, taking as a case a region located between States of Pará and Tocantins, close to the Araguaia-Tocantins waterway. Within the categories of linear programming models, the particular case called transport and transshipment problem was used. The model aimed to minimize transport costs from the production centers to the exporting port, through the current infrastructure and, under different scenarios of intermodal alternatives formed by the project of Ferrovia Paraense S.A. and by Araguaia-Tocantins waterway, the year 2019 and production projections are considered for the year 2029. The results showed that the scenarios with waterway transport bring greater benefit to the region, achieving savings of up to 23%. Furthermore, the Vila do Conde port complex expands its zone of influence, thus obtaining increase in the quantity exported in up to 1059.7%. As well, it confirms that the State of Pará is the one that most needs an intermodal alternative. Furthermore, the routes were configured in new transport networks, reducing the distances traveled in the road modal to transport production from the municipalities, reducing the flow on the main highways. Thus, it is concluded that intermodal transport improves regional competitiveness and favors the development of States.Item Acesso aberto (Open Access) 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/5044859479302394The 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.Item Acesso aberto (Open Access) 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/0000-0003-0214-0587Social 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.Item Acesso aberto (Open Access) 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/0000-0003-0214-0587Maritime 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.Item Acesso aberto (Open Access) Análise de esforços resultantes de impactos entre barcaças de comboios fluviais para modelagem de um sistema de amortecimento de choques utilizando teoria de análise multicorpos(Universidade Federal do Pará, 2018-03-09) CRUZ, Fernando Costa da; SOEIRO, Newton Sure; http://lattes.cnpq.br/7303174583088137; https://orcid.org/0000-0003-4224-767XIn this dissertation an analysis is performed on the operational behavior of river barges convoys in navigation regions with presence of waves, winds and currents. A study is carried out to determine the applicant forces present in the mooring elements and in the contact points between barges in flotillas when they are sailing in dangerous navigation conditions. A theoretical study is carried out, identifying the main response movements of floating bodies. In this case, a model is developed using the ANSYS AQWA 17 software to identify the stress levels from impacts between barges that make up the formations, as well as the degree and behavior of the tensile stresses present in the mooring ropes over time. In addition, a practical study is used as a comparative model of data, being very important for the validation of the results achieved by the computational model. In this way, the proposed scenario within the computational program describes environmental characteristics to describe the navigation problem in a clear way. At the end of this work the levels of effort captured within the computational model are presented, being divided into two models of fluvial flotillas, a convoy with barges for soybean transportation, and another with barges for the transport of iron ore, being discriminated the locations of the higher levels of effort. It is important to note the pioneering role of this work in relation to the problems perceived within the area of operational safety of fluvial flotillas, using Finite Element tools as the main evaluation tool.Item Acesso aberto (Open Access) Diagnóstico numérico em embarcações de atendimento de atendimento médico-hospitalar visando à otimização vibro-acústica(Universidade Federal do Pará, 2017-11-10) FERREIRA, Aracelli Suzane Andrade; SOEIRO, Newton Sure; http://lattes.cnpq.br/7303174583088137; https://orcid.org/0000-0003-4224-767XThe use of vessels for hospital care has been one of the main means used by some prefectures belonging to the states of the Legal Amazon to take medical and dental care to communities located in distant locations. These vessels were named by the Ministry of Health of Basic Units of Fluvial Health (UBSF). The design of these units, however, is differentiated in many ways, since it provides for the installation of equipment not present in other conventional vessels. In addition, the service performed in these units requires satisfactory acoustic-vibro-conditions so that health professionals can perform the procedures correctly. This work aims to perform a numerical analysis through the Finite Element Method to evaluate the modal and acoustic properties of the medical service vessel. The work contemplated two analyzes: modal and acoustic. In the modal analysis, the axis, propeller and the structure of the UBSF were considered as objects of study, as these are the main sources of excitation. The acoustic analysis sought to ascertain the main sources of noise emission and its propagation within the UBSF. In this second analysis, it was possible to predict the overall sound pressure level and octave bands inside the vessel. The Ansys and Comsol softwares were used for the modal and acoustic analysis, respectively. After the analyzes, the data obtained with the main national and international standards related to the subject were compared. The results found in this study demonstrated that the reference model proposed by the Ministry of Health did not meet the criteria established by the norms. It is proposed, therefore, as solutions to attenuate the undesired effects from the acoustic-acoustic phenomena, the use of materials with absorptive properties and increase in the structural rigidity of the vessel. Such measures would allow users and crew members to improve the comfort and conditions of basic health care services.Item Acesso aberto (Open Access) 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/0000-0003-0214-0587The 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.
