Análise das dificuldades da logística humanitária praticada junto aos ribeirinhos do Tarumã Mirim durante a seca extrema amazônica de 2024 e propostas de mitigação
(2025-08-18) Silva, Roger Farias da; Silva, Daniel Nascimento e
This study aimed to analyze the difficulties of humanitarian logistics practiced among the riverside dwellers of the Tarumã Mirim River during the drought and to propose courses of action capable of mitigating its harmful impacts. The survey method was used, with data collected through semistructured interviews and observation with a sample intentionally chosen from among the actors with the most significant participation and knowledge of the logistics actions practiced, analyzed with semantic and content analysis techniques, and the results presented in summary tables. The results showed that the difficulties in a) transporting goods were the reduction in river levels and the appearance of sandbanks and rocks; b) in the distribution of essential services were the failures in the supply of water and energy and health and education; in communication, the existence of few transmission towers, the lack of fiber optics, the lack of satellite communication and the high prices of communication equipment; d) the impacts of the difficulties were the reduction in the transport of goods, the impossibility of river traffic and the inability to carry out environmental logistics; and e) mitigation was to create infrastructure and access to water resources, improve transportation infrastructure, promote economic resilience, preserve the environment with sustainable resource management, strengthen participatory public policies and partnerships and universalize information and communication technology. The conclusion points to the lack of systematic humanitarian logistics during the 2024 drought, whose actions were closer to improvisation than those of other regions cataloged in scientific databases.
Análise das dificuldades na coleta de resíduos sólidos do ponto de vista de um coletor na cidade de Manaus, Brasil
(2023-12-28) Santos, Thiago Augusto Moreira dos; Tino, Cláudio Fernandes; Silva, Daniel Nascimento e
A large part of humanity already understands that natural resources are finite. It is, therefore, necessary to reuse all the materials and products we use as many times as possible, which has become an increasingly growing challenge. In this sense, this study aimed to analyze the main difficulties encountered in the selective collection of solid waste in Manaus from a collector's perspective. For this, the method used consisted of the following steps: a) elaboration of a theoretical architecture about the stages of the reverse logistics process, b) creation of an interview script based on the elaborate architecture and guiding questions, c) data collection with the member of a group of collectors, who explained and exemplified the interviewee's answers, d) organization of the collected data and generation of answers to the guiding questions. The results showed that five were the main difficulties encountered, which were classified as environmental (regional climate), conscientious (the lack of willingness of the population to collaborate with selective collection), transportation (lack of material and equipment), and commercial (the pricing of materials is not rewarding). The conclusion shows that only the environmental factor cannot be controlled. However, its effects can be mitigated if the other four difficulties are practiced, which is not a simple task.
Análise de aplicações da inteligência artificial na armazenagem de materiais: um estudo bibliográfico
(2025-04-09) Montenegro, Samara da Costa; Veloso, Jhuly de Souza; Silva, Daniel Nascimento e
This study aimed to analyze ten publications that portray the application of artificial intelligence in material storage. The conceptual bibliographic method was used in its four stages: a) formulation of primary and accessory research questions, b) data collection in scientific databases, c) analysis and organization of the collected data, and d) generation and interpretation of the answers to the formulated research questions. The results showed that the goals of the studies focused on problematic situations that can be considered complex, the methods of the studies consisted of numerous techniques and procedures, the artificial intelligence tools applied in the studies were varied and in large quantity, and the results and conclusions of the studies show that artificial intelligence is a technology that can effectively solve problems and help to overcome storage challenges. The conclusion points out that the more complex the problem or challenge to be faced, the greater the effectiveness of artificial intelligence in solving or helping to overcome it. The study's main contribution to science highlights the need for logistics and storage professionals to know and know how to apply artificial intelligence in logistics practice.
Análise do processo de armazenamento de materiais de uma organização industrial em Manaus, Brasil
(2025-04-08) Silva, Rayson Gustavo de Castro; Encarnação, Gessyca Sousa da; Silva, Daniel Nascimento
This study analyzed the stages of the materials storage process in an industry operating in the industrial hub of Manaus. The research was based on the theories of processes and storage to build a theoretical architecture that summarizes the state of the art. The method used was a survey, with data collected using a semistructured interview script and another observation script, analyzed using the client-supplier technique and organized using tables summarizing the stages and their contents and objectives. The results showed that a) there are eight stages in the storage process used, including a previous stage of weighing the material; b) the more complex stages are performed with a greater number of sub-stages, which allows for fewer failures in the operations as the labor force and technological instruments are specialized in their execution; and c) the specific objectives of each stage are aligned with the intended objective of the storage process. The findings show that the empirically observed stages are in line with the theoretical architecture of the study, with the first and last stages being, respectively, reception and dispatch, and the intermediate stages varying according to the type of material and specificities of the production process. The main contributions of the study to science were the proposition of a conceptual definition for the materials storage process and the confirmation that this process begins with reception and ends with dispatch, differing in the intermediate stages.
Uma análise dos estudos científicos brasileiros sobre armazenagem de materiais disponíveis no Google acadêmico no ano de 2023
(2024-07-05) Viana, Eliane Pereira; Martiniano, Alexandre Lopes; Martins, Gilbert Breves; Silva, Daniel Nascimento e
Purpose: This study aimed to analyze the scientific productions on storage in the Google Scholar database in 2023. Theoretical Structure: The study's theoretical structure focused on the conceptual and operational aspects of the storage process in its various dimensions and analytical categories, enabling the understanding of the main aspects of the national scientific production published in Brazilian journals, platforms, and repositories on storage. Design/Methodology/Approach: The conceptual bibliographic method was used in its four stages: the formulation of research questions, with exclusion criteria and appropriate response standards, data collection in scientific databases, organization of data in figures and other diagrammatic schemes where the responses generated can be visualized, and presentation of the results in specific communication products for evaluation by the scientific community. Findings: The results showed that a) the most frequently discussed topics in the publications were storage, storage, and specific aspects of stored materials, b) theoretical-empirical studies were predominant, c) several different methods were used to generate the findings, with the experimental method prevailing, d) most of the studies aimed to apply the knowledge generated, e) only one-third of these publications were in journals and proceedings of scientific events. Research, Practical, and Social Implications: The findings show that Brazilian journals and scientific communities prioritize theoretical-empirical studies, especially those that have the potential to be transformed into techniques and technologies. The implications are much more impactful if the production is geared towards agribusiness. Originality/Value: The study shows the theoretical-empirical trend of research on storage, mainly because it is primarily carried out by engineering areas, which seek to solve problems that the agribusiness industry has faced in its challenges of increasing the efficiency of its production process combined with the increasing quality of its products

Desafios Logísticos do Transporte Fluvial Amazônico
(2025-03-11) Taveira, Nélio Junior Batista; Alves Neto, Me. José Luciano Rodrigues
The Amazon region is known for its stunning landscapes and extensive rivers. These characteristics influence the waterway modal to be the main one in the region, but it is necessary to consider correct and effective ways to deal with the ebb and flow that year after year has become more extreme and prolonged, impacting the local economy and the daily life of inhabitants and companies. The objective of this work is to reflect on the general aspects of transport logistics, understand the waterway model and how it develops in the Amazon River. In addition, being a modal completely linked to environmental issues, we will analyze actions aimed at sustainability and environmental health. From this we will narrow the research to the consequences perceived in the Manaus Industrial Pole by local professionals and generate reflection on the main consequences of the lack of planning, the real needs for change and possible actions to combat the difficulties present in the dry season of the rivers in the Amazon.

(2022-11-28) Bastos, João Victor Pereira; Nascimento-e-Silva, Daniel
Estudos científicos cada vez mais têm mostrado que o que se chama lixo na verdade são recursos desperdiçados, tanto sólidos quanto de outras naturezas. Grande parte desses resíduos são gerados no interior dos domicílios urbanos e rurais, o que força os cidadãos a repensarem seu comprometimento com o reaproveitamento do que muitos ainda consideram como lixo. Este estudo teve como objetivo explicar quais são as principais dificuldades para a realização da coleta seletiva de resíduos na cidade de Manaus. Utilizou o método de levantamento, mas com a finalidade de gerar explicação aprofundada sobre como essas dificuldades acontecem, invertendo-se a lógica tradicional desse método. Os dados foram coletados através de um questionário eletrônico, com questões abertas, organizados e analisados com o uso de técnicas semânticas e os resultados foram gerados com as recomendações do método científico-tecnológico. A conclusão apresenta seis tipos distintos e interconectadas de dificuldades que impedem a efetividade da coleta seletiva de resíduos na cidade.

This study described collectors' main difficulties in collecting discarded materials in Manaus (Brazil). The method used involved analyzing the practice of three collectors willing to provide in-depth data and information obtained through semi-structured interviews carried out in the respondents' workplaces, which were then analyzed with the help of the conceptual bibliographic method and interpreted with the help of semantic analysis. The results showed that a) the main difficulties are extreme physical exertion, people's rejection, unhealthy working conditions, lack of personal protective equipment, and lack of participation by people, companies, and governments; b) difficulties occur due to lack of equipment, lack of technical knowledge of the materials handled, people's lack of knowledge about the importance of the collectors' work and lack of participation by society and governments in the selective collection; c) who could help to minimize these difficulties are the residents, companies, and governments and d) what the agents can do is to structure the collection (government), separate the materials (residents), provide more disposal sites (town hall) and donation of equipment and training (companies). The conclusion shows that agents are not prepared to carry out reverse logistics in the city because they are unaware of the importance of waste pickers' work to start the city's circular economy.

This paper explores essential strategies in inventory management, highlighting cross-selling, the use of Big Data tools, and effective inventory control practices. Initially, we address the relevance of cross-selling as a strategy that goes beyond increasing sales, providing a personalized experience to the customer. We discuss the positive influence of Big Data tools on data analysis and demand forecasting, emphasizing their contribution to improving operational efficiency, especially using Python programming. The discipline of inventory control is examined, focusing on its importance in cost optimization and maintaining the balance between supply and demand. By exploring the practical application of these concepts, we highlight the importance of demand forecasting and efficient inventory layout for cross-selling strategies. We conclude by recognizing that data analysis is the central element of these practices, providing crucial insights for informed decisions and continuous improvements.

Propósito: El comercio electrónico es una satisfacción de necesidades propias de la era de la información. Basado en tecnologías contemporáneas, ha representado un canal emergente para multiplicar las posibilidades de satisfacer demandas en prácticamente todo el planeta. Para poder mejorarlo constantemente, los científicos y directivos se han preocupado por comprender mejor el comportamiento de los compradores online. En este sentido, este estudio tuvo como objetivo identificar los factores determinantes del comercio electrónico según aspectos demográficos (frecuencia de compra, ingresos, actividad remunerada, edad y género) de estudiantes universitarios de una institución del Norte de Brasil. Marco teórico: El estudio se basó teóricamente en los factores y variables que determinan el comportamiento de compra del consumidor. Los factores como dimensiones analíticas formaron una arquitectura teórica, cada uno compuesto por sus respectivas variables y categorías de análisis. Diseño/Metodología/Enfoque: El método utilizado fue una encuesta, cuya población estuvo conformada por 51 estudiantes matriculados en el segundo semestre de 2022, de la cual se extrajo una muestra de 47 encuestados, ya que los demás abandonaron las clases. Los datos fueron recogidos mediante un cuestionario con preguntas cerradas, cuya validez fue verificada mediante la prueba alfa de Cronbach de 0,82, considerada muy conforme. Los resultados se generaron mediante la prueba U de Mann-Whitney, ya que el comportamiento de las variables no fue considerado normal por las pruebas de Kolmogorov-Smirnov y Shapiro-Wilkens. La conclusión apunta a un tipo de democracia virtual en la que se percibe poca diferenciación en los factores determinantes de las compras desde el punto de vista de las variables demográficas estudiadas.
Gestão de resíduos orgânicos gerados no restaurante do IFAM-CMDI e a distribuição de alimentos pela assistência estudantil - IFAM-CMDI
(2018-11-07) Alencar, Vanessa Galvão; Machado, Ana Lúcia Soares; Melo, Larissa Alencar de
The generation of organic waste in Brazil, has alarming data, there is a culture of waste in the country, this fact was verified in an educational institution in the provision of daily meals to students who participate in a PNAES. However, not all students who submit to the edict are considered due to insufficient resources. Faced with this was thought how to reduce the waste of food, as well as the disposal of organic waste, reverting them in more benefits. In this way interviews and weighing and in loco observation of the wasted foods and the causes of this done, as well as possible solutions were made. Therefore, the objective of the research, from the standpoint of environmental management and reverse logistics, was to elaborate a data collection about the distribution of food and evaluate the effectiveness of the supply chain management and its characteristics. To point out how logistics works in this food supply process at IFAM - CMDI. Thus, during the month of analysis, the average number of dishes served to the 220 students was approximately 800 grams of food per dish, thus calculating the total wasted in the month, which was 124 kg of waste ingestion and 254 kg of bark of the preparation, it can be said that approximately 472 food dishes could have been provided the most in the month, benefiting more students with the social benefit related to food. If the knowledge of management and reverse logistics is implemented to make food distribution more effective, with fewer losses and to analyze ways of transforming losses into gains, within an educational process, it will be possible to contribute to a better service of the PNAES.
A implementação da Logística Reversa na região interiorana do Amazonas
(2025-03-15) Souza, Sara Farias de Almeida
This study explores the implementation of reverse logistics in the interior region of Amazonas, focusing on the practices and challenges of this crucial activity for sustainability. Reverse logistics in the region involves the collection, sorting, and shipping of recyclable materials to recycling centers, which are mainly concentrated in large urban centers like Manaus. In cities such as Manacapuru and Parintins, local associations and companies play essential roles in waste management despite infrastructure limitations. The research, which includes a literature review and case study analysis, reveals that reverse logistics contributes to both environmental and economic sustainability by enabling the reuse of materials and reducing the need for virgin resources. However, its implementation faces challenges such as the lack of local recycling industries, the need for greater public awareness, and resistance to change. A success story like Fábrica Móveis Albuquerque in Parintins demonstrates the effectiveness of local initiatives but also highlights the dependence on infrastructure and support from larger urban centers.

(2021-07-19) Rodrigues, Paulo Hercílio Duarte de Freitas; Tino, Cláudio Fernandes; Tino, Cláudio Fernandes; Silva, Jefferson Fernando da; Silva, Marcos Carneiro da
in such a competitive market. The research was delineated in a bibliographic review in books, articles and magazines that present high impact factors, national and international specialized journals. The results show that integrating logistics has as one of its main objectives to minimize costs and allow all demand provided by the market to be met. An efficient logistics process has the power to offer the customer a level of service excellence by meeting the delivery deadline set by the company upon purchase. The current context shows us that with each passing day, customers are more often seeking a level of service excellence. This makes companies increasingly committed to not only reducing their costs, but also pleasing their customers in equal proportions. It follows that in a very competitive market, logistics expenses can offer an important competitive advantage for companies that are developing an effective system. Competitive advantage comes from services tailored to the company's special product requirements, making costs more efficient for each logistics element, acting responsibly, providing reliable service, good information, flexibility, good use of capacity, efficient inventory and loss prevention.
