This study assessed the life cycle costs of eucalyptus production in a Brazilian forestry company. The analysis combined traditional Economic Feasibility Analysis with Monte Carlo Simulation and Real Options to account for uncertainty. Results confirmed the project's economic viability, with the Reform/Coppice or Reform/Conduction scenarios offering the highest returns. Wood price and production levels were the most influential factors. The most cost-effective approach involved chemical fertilization and manual ant control. The study highlights the value of integrating probabilistic methods into cost analysis, enhancing decision-making and identifying opportunities to reduce costs in the eucalyptus production cycle.

This paper aimed to optimize the cashier service macroprocess in a supermarket located in the Alto Paranaiba. Decision-making tools were applied, such as brainstorming, process mapping, Ishikawa diagram and PDCA cycle. The simulation type was based on the M/M/1 model, in the context of Queuing Theory. Thus, factors such as customer satisfaction and increased productivity were sought through systematic control and continuous improvement of the cashiers' service macroprocess. Finally, the alignment carried out between the PDCA cycle and the Routine Management brought an effective contribution, represented by the standardization of the macroprocess, by the construction of Standard Operating Procedures (SOPs).

Background: Agricultural production plays a vital role in the global economy by integrating different sectors and promoting capital circulation across industries. In this context, the dairy sector emerges as a promising avenue for investment. This study aims to assess the economic feasibility of establishing a dairy plant for the production of parmesan and mozzarella cheeses in Lavras, MG, considering both deterministic and probabilistic scenarios. Methods: The analysis was conducted in three stages: data collection, deterministic economic feasibility analysis using traditional financial indicators (NPV, IRR, profitability rate, and payback), and a probabilistic assessment using the Monte Carlo simulation with 100,000 iterations to incorporate uncertainty into the model. Results: The deterministic results indicated a positive Net Present Value (NPV), Internal Rate of Return (IRR) exceeding the Minimum Attractiveness Rate (MAR), and a profitability rate above 1.5, validating the investment’s viability. The probabilistic analysis reinforced these findings, with over 80% of simulated scenarios resulting in a positive NPV and over 77% showing IRR above the MAR. Key variables influencing profitability included market share, Class AB cheese consumer percentage, parmesan markup, operational costs, and per capita cheese consumption. Conclusions: The study confirms the economic feasibility of implementing the proposed dairy plant. The integration of Monte Carlo Simulation enhanced the robustness of the analysis by accounting for uncertainty, providing valuable insights for strategic decision-making. The project presents strong potential for regional development, job creation, and income generation.

O presente artigo trata de uma análise das atividades realizadas por funcionários de uma empresa do setor têxtil focada na confecção de camisas e situada na região do Alto Paranaíba, Minas Gerais. O trabalho teve como objetivo realizar um diagnóstico sobre até que ponto a empresa utiliza da gestão por processos e entender como os conceitos de qualidade são difundidos pela organização, visando com isso mapear o processo produtivo das camisas de modo a identificar os problemas existentes. As observações e entrevistas feitas na empresa mostraram que esta não utiliza de maneira efetiva da gestão por processos, bem como não aplica ferramentas gerenciais da qualidade. Um dos principais problemas identificados foi a falta de padronização do produto, e por meio de ferramentas usadas ao longo do artigo foi possível propor melhorias, a fim de contribuir com o crescimento da confecção e ampliar o conhecimento dos autores.

The present study deals with a statistical analysis of the production process in an organization in the food sector, specifically, in the branch of roots. In addition, this study is characterized by the use of a hybrid analysis with the fusion of qualitative and quantitative aspects in order to improve the generation of knowledge as well as to facilitate the interpretation of the results obtained. As a work methodology, the control chart by variable was developed from data collected during visits to the organization. The study also carries out an approach on the capacity indexes from the perspective of the cassava packaging process as well as an analysis of the percentage of items outside the specifications. It is worth mentioning the use of the Ishikawa diagram to identify root causes of process variability, in addition to proposing corrective measures for such causes. Finally, according to the analyzes carried out, the organization in question presented an efficient and quality product packaging process, since all samples were within the control limits established statistically and the percentage of items outside the specifications was showed reduced, meaning only approximately 3%. El presente estudio trata de un análisis estadístico del proceso productivo en una organización del sector alimentario, específicamente, en la rama de raíces. Además, este estudio se caracteriza por la utilización de un análisis híbrido con la fusión de aspectos cualitativos y cuantitativos con el fin de mejorar la generación de conocimiento, así como facilitar la interpretación de los resultados obtenidos. Como metodología de trabajo se desarrolló el cuadro de control por variable a partir de datos recolectados durante las visitas a la organización. El estudio también realiza una aproximación a los índices de capacidad desde la perspectiva del proceso de empaque de la yuca así como un análisis del porcentaje de partidas fuera de las especificaciones. Cabe mencionar el uso del diagrama de Ishikawa para identificar las causas raíz de la variabilidad del proceso, además de proponer medidas correctivas para dichas causas. Finalmente, de acuerdo a los análisis realizados, la organización en mención presentó un proceso de empaque de productos eficiente y de calidad, ya que todas las muestras se encontraban dentro de los límites de control establecidos estadísticamente y el porcentaje de artículos fuera de las especificaciones se mostró reducido, es decir solo un 3% aproximadamente.
