• FUZZY Methodology Applied IN THE EVALUATION OF THE QUALITY Of Hospital SERVICES. Case Study IN A HOSPITAL In Amazonas
  Background: There is currently an important challenge for hospital companies, which is to offer their services with the highest quality to their customers. And meeting this demand requires more efforts from public or private organizations to provide quality services offered to customers who are more demanding and interested not only in cost, but in the quality of the product or service offered. Therefore, if you guarantee in the market, you have an unknown, to evaluate the quality of services to monitor the quality of service according to the expectations of your customers, thereby creating competitive advantages. In this context, the private hospital in Manaus is with an interest in measuring its quality, placing itself as an object of study, in order to know: the quality of the services offered by the Hospital in the view of the clients, identifying the relevant positive and negative aspects for that the Hospital can act more precisely on the points that allow it to achieve excellence in customer service and acquire more competitiveness. Materials and Methods: This reality dictates the need to create effective methods to meet the demand for quality in hospital services. In response, the purpose of this study arises to create a quality assessment model using the Fuzzy inference system, based on the studies by Parasuraman, Zeithaml and Berry, in 1994, who developed the SERVQUAL scale, an efficient instrument to assess the quality of services with evaluative diagnosis of quality that are important and followed until today. Results: For this, a model was developed to evaluate the quality of private hospital services in Manaus. The questionnaire was used as data collection techniques, as determined by the SERVQUAL scale, which generated variables that were used for Fuzzy Inference in the Matlab R16 Student software. Conclusion: The results made it possible to evaluate the quality of customer service, which reached an index of 82.7%, thus identifying the level of customer satisfaction, highlighting the negative points, essential information for managers to implement appropriate improvements.
• Mobile technology to optimize the operational control of the entry of national goods in the areas administered by suframa: vistoria 4.0
  A Zona Franca de Manaus (ZFM) é uma área com incentivos fiscais e parafiscais criada para estimular o desenvolvimento econômico na região Amazônica. Em 2021, a região recebeu mais de 53 bilhões de reais em mercadorias (SUFRAMA, 2022), o que, juntamente com sua vasta extensão territorial e infraestrutura precária, apresenta desafios logísticos que dificultam a fiscalização e tornam a região propensa a fraudes fiscais, como o desvio de mercadorias e o uso indevido de incentivos fiscais. Essas práticas ilegais prejudicam a economia local e nacional e podem prejudicar a imagem da autarquia. O projeto é composto por três pilares: comercial, agropecuário e industrial (REY e JÚNIOR, 2019). Com isso em mente, este trabalho propõe um aplicativo que utiliza tecnologias de informação para aumentar a eficiência e segurança do processo de fiscalização de mercadorias. Dividiu-se os trabalhos em três etapas: Elicitação dos requisitos; Elaboração do protótipo; Levantamento dos pontos de função e estudo de viabilidade e o aplicativo utilizará tecnologias embarcadas, como a Optical Character Recognition (OCR) e a Geolocalização, permitindo que os próprios destinatários das mercadorias realizem o procedimento de vistoria física de forma segura. Foram elicitados os requisitos funcionais e não funcionais do aplicativo e as telas das interfaces foram elaboradas no software FIGMA. Também foi realizada uma análise do potencial ganho de produtividade do controle de mercadorias, onde foi verificado que apenas com medicamentos e veículos, foi possível aumentar a produtividade quantitativa das vistorias físicas em 7,5%, passando dos atuais 2,5% definidos como meta institucional para quase 10% do total dos valores das notas fiscais registradas na autarquia. Além de melhorar a eficiência do processo de fiscalização na ZFM, o aplicativo alcançará 100% da área de controle cobrindo todos os 157 municípios incentivados da região. Atualmente, apenas 11 cidades têm sedes administrativas e vistorias físicas (Suframa, 2022). Foi constatado que o baixo investimento necessário para o desenvolvimento do aplicativo, em comparação com a contratação de servidores para realizar o mesmo número de vistorias físicas, é vantajoso pela sua economicidade. A utilização de tecnologias da informação para fortalecer o controle de entrada de mercadorias é uma opção econômica, prática e sustentável que pode fortalecer o processo de fiscalização e minimizar os riscos de fraude.

• Use of chirps satellite precipitation in the characterization of the franceses stream Basin, Manaus - State of Amazonas - Brazil
  The city of Manaus has numerous waterways in its urban perimeter, and, despite this, there is a shortage of measures aimed at protecting water resources that has generated occupations very close to the riverbeds. This work aims to characterize a watershed in an urban area of Manaus and map the areas subject to flooding around the Franceses Stream. The methodology applied involved obtaining topographic and thematic information such as morphology, geographical location, elevations, extent, area, level curves (water dividers) of the basin, obtained through georeferenced satellite images in a GIS environment.In addition, monthly satellite precipitation via the CHIRPS product was used for the calculations. The physical characteristics of the basin were determined using equations employed in hydrology. The results indicated that the Franceses Stream basin is not subject to major flooding, presenting the following characteristics: compactness coefficient Kc = 5.71; form factor Kf = 0.36; circularity index Ic = 0.03; drainage density Dd = 0.94km-1 . It was also found that, despite the intense occupation, there is preserved vegetation within the basin. It was concluded that the precipitation estimated by CHIRPS is efficient because it has a larger coverage, and that knowing the characteristics of watersheds in urban environments is of great importance to subsidize intervention measures and planning policies that ensure the protection of water resources and minimize inconvenience to the population. It was also found that the use of GIS is an important tool for analyzing information in hydrological studies, and that it needs to become an increasingly applied tool in urban management, so that the knowledge obtained can be used to obtain better environmental and social conditions.

• RAIN PREDICTION MODEL USING ARTIFICIAL NEURAL NETWORKS
  Precipitation is important in maintaining the environment and life of living beings. Through their studies and increasingly accurate forecasts, we can reduce the impacts related to floods, environmental disasters, and losses in the agricultural and tourism sectors. However, climate change has made the analysis of this variable difficult. In this article we will present an hourly rain forecast model using Artificial Neural Networks, using the information on instantaneous, maximum and minimum temperature, relative humidity, wind, and precipitation through the automatic weather stations of the Instituto Nacional de Meteorologia, located in the city from Manaus/AM. First, a study was carried out to determine the network architecture best suited to the data set. Numerous combinations between the training and transfer functions were performed until finding the functions that presented the best error values. The predictions made with the model showed satisfactory results, showing that the model was able to reproduce the same behavior of the precipitation observed for the predicted day, presenting practically the same totals, especially on the rainiest days. On the other hand, in cases where the observed showed a characteristic of convective precipitation, the model was not able to capture the intensity, which shows that it must be tested with other atmospheric variables.
• APPLICATION OF FUZZY LOGIC FOR DECISION-MAKING IN THE CRITERIA FOR ALLOCATION AND DISTRIBUTION OF INDUSTRIAL COSTS.
  Background: Industries are increasingly specializing in the financial and production sector, aided by general accounting and, especially, cost accounting. Even increasing the degree of complexity of specialized employees, cost accounting in relation to its apportionment criteria is always a challenge. Companies find it very difficult to correctly determine the unit cost of the product or service being offered. And it is precisely at this moment that cost accounting proves to be useful and indispensable. Cost apportionment is one of the branches of industrial accounting and it is a subject that seems to be simple to understand, however, it becomes more complex during your daily practices. This work aims to develop a classification model for decision making based on Fuzzy Logic for diagnosing production performance with a focus on financial improvement based on the optimization of cost apportionment. In this context, the work is justified by pointing out a new perspective of analysis through production and financial indicators implemented in a Fuzzy interference model with the objective of optimizing the apportionment criteria and proposing financial improvements. Materials and Methods: The Methodological Process of the research was developed in three phases: 1. Identification of Economic and Production Indicators; 2. Modeling of the Fuzzy “Inference” System; 3. Proposed Model Experiment. Each phase consists of three stages until reaching the results obtained from the research. The proposed Fuzzy system was able to show the different performance results when simulated with the different conditions of the input variables and which the projected performance classification could be defined. Results: The model resulted in 576 inference rules for analysis. In one of these analyses, I specify analysis 291 according to table 8 of this article, considering the indicator of Overall Labor Effectiveness “Good”, Overall Equipment Effectiveness “Bad”, Contribution Margin “Good”, Breakeven Point “Good” and Liquidity Current “Good”, the performance of the product is considered “Medium”. With a bad EGE, it is difficult to properly monitor production efficiency to a satisfactory degree, but you can maintain a standard production pace due to the good results of other indicators. Conclusion: In this way, the Fuzzy system helps to guide us in which costing method we should adjust the worked product so that it can generate profitability within the industry and better profit margin, allowing a more critical analysis in internal decision-making.
