Reverse logistics is a concept that involves managing the reverse flow of products and materials focusing on reuse, recycling and adequate disposal of products at the end of their useful life, aiming to reduce environmental impact and ensure efficiency and sustainable development of products and productive processes. Currently, academic discussion in this regard is increasing and the research carried out offers, for the most part, practical answers for companies in facing obstacles to the implementation of reverse flows and highlights the economic and environmental advantages resulting from this practice. In order to understand the lack of implementation and investments of reverse flows in productive processes, the present work aims to identify the main barriers to its implementation in the electronics industries of the Manaus Industrial Complex. To this end, a systematic review of the literature was carried out, through which we can better understand the state of academic research on this subject and which made it possible to identify a series of barriers, which were categorized, selected and validated by industry experts and academic professionals based on questionnaires. Their responses were compiled creating an overall prioritization of the list of barriers. From then on, the decision making trial and evaluation laboratory method (DEMATEL) was used, which determined which barriers were most impactful based on the opinion of experts in order to obtain the level of relationship that a group of barriers exerts on another group. The purpose of this instrument is to offer for managers and decision makers a conceptual framework for understanding the difficulties of implementing reverse logistics practices in the Manaus Industrial Complex.
Logística de Distribuição de Produtos Farmacêuticos no Estado do Amazonas

In river logistics in the Amazon, the distribution of medicines and health products faces significant challenges, requiring managers to constantly seek to reduce impacts on the population and improve operational efficiency. The study was conducted in a company based in Manaus/AM and focused on the process that begins in the dispatch area of the distribution center until delivery to the customer. The stages of transportation and distribution of medicines and health products are carried out in accordance with the carrier's processes, which is responsible for ensuring the quality of the medicines. To carry out this study, a process mapping was developed using BPMN (Business Process Model and Notation), which establishes a standard for representing processes using graphs and diagrams. In addition, digital simulation was employed to evaluate the performance of the current process, critically analyze the mapped processes in accordance with current legislation, and propose improvements based on the mapping and critical analysis.
MODELO PARA AVALIAR O DESEMPENHO DA LOGÍSTICA INTERNA

The market has demanded efficiency, effectiveness, creativity, and agility from organizations, requiring them to be competitive and sustainable. Logistics is a fundamental strategic link, yet the literature lacks studies on the organization and evaluation of internal logistics. This thesis aims to develop a Model to Evaluate the Level of Internal Logistics Performance, identifying its component parts and how they are structured and measured. The study was based on bibliographical, bibliometric, and empirical research, identifying a gap. A methodology with 16 steps was developed, using multicriteria methods, Solver Excel, and the Fuzzy Logic toolbox (MATLAB). Initially, 15 component parts of internal logistics were established, adjusted, and validated as 13 through interaction with industry specialists. The model was tested in three companies, confirming consistency in the analyses with 95% accuracy. Results include identifying component parts, defining priority weights, properties of components, and a mathematical equation to calculate an index defining the Model, offering both conceptual and practical contributions to the literature and business competitiveness.
Modelo para estimar o risco de ruptura pela falta de abastecimento de insumos, com base em simulação digital – o caso de uma indústria de eletroeletrônicos

The supply flow of components for the manufacture of technology products has been suffering restrictions in its supply dynamics, due to the increase in market demand for more sophisticated products, by the exclusivity of a few manufacturing plants in the global supply, limitations of transportation infrastructure and natural impacts that affects the flow of cargo transportation. This context has resulted in the worsening of the global supply crisis for the electrical and electronic goods industry, in particular for the automotive industries, from 2020 onwards. Faced with this scenario of uncertainties, this study aimed to create a model that estimates the risk of disruption in a manufacturing process of an automotive electrical and electronic product, for periods, due to the lack of supply of inputs and through a case study. This study development examined how traditional production planning and control systems are integrating with new information technologies enabling to obtain an accurate data for predicting disruption risks. The model is based on real data and requirements generated by Production Planning and Manufacturing Resource Planning (MRP) calculation to determine the disruption point, integrated within a Low Code Development Platform (LCDP) digital platform. To facilitate the achievement of the objectives, a four-step was developed. First, the steps of the production process and of the inputs supply planning were mapped, based on the production planning. In the second step, it was created a method for calculating the consumption and the point of disruption of the inputs in the production process, based on the requirements generated by production planning. In the third stage, the choice of the supporting digital platform was determined, whose selection criterion was determined by the evaluation of the artificial intelligence elements contained on it and by the complexity of the programing codes. Finally, the application of digital simulation by the real data. The results achieved can be mentioned: a model that estimates the rupture of the production process by the date of and the period involved in the disruption. By this study it was identified 66% of production plan coverage from the total production plan of the period due to the disruptions found. The contribution to the literature through a model that estimates the risk of disruption of a production process, through a digital tool.
