Resumo: Purpose: The objective of the study is to apply the Monte Carlo Simulation (SMC) to the management of inventories in a small pharmacy. Methodology: With the characteristics of exploratory and descriptive research, the present research was used of real data collected in a small pharmacy, and with the participation of the manager and pharmacist. Twenty-two drugs considered of high turnover were selected for the modeling test. The daily demand was then observed for 22 consecutive working days, to determine the parameters of the model to be used. For the modeling, the Monte Carlo Simulation technique, proposed by Corrar and Theóphilo (2004). Results: The model was applicable and easy to use by managers. In the analysis examples, DRAMIN showed that the minimum stock increase from 60 units to 100 units would increase the attendance rate from 87% to 92.3%. It was also observed in the unit of analysis that some drugs, as in the case of DORFLEX could have their inventories reduced by more than 300%, that the same efficiency would be maintained in relation to the demand. Contributions of the study: This paper contributes to the literature of management controls, pointing to techniques of operational research for stock management. In addition, it makes a valuable contribution to small pharmaceutical companies by assisting them in using the use of simple statistical tools to improve the efficiency of inventory investment and consequent financial performance.

Metodología: Con características de investigación exploratoria y descriptiva, la presente investigación se utilizó de datos reales recolectados en una farmacia de pequeño porte, y con participación del gestor y farmacéutico. Se seleccionaron 22 medicamentos considerados de alta rotatividad, para la prueba de modelado. En seguida se observó la demanda diaria por 22 días hábiles y consecutivos, para la determinación de los parámetros del modelo a ser utilizado. Para el modelado se utilizó la técnica de Simulación de Monte Carlo (SMC), propuesta por Corrar y Theóphilo (2004). Resultados: El modelo se mostró aplicable y de fácil utilización por parte de los gestores. En los ejemplos de análisis del medicamento DRAMIN fue posible verificar que el aumento de stock mínimo de 60 unidades para 100 unidades elevaría el índice de atención del 87% al 92,3%. También se observó en la unidad de análisis que algunos medicamentos, como en el caso del DORFLEX, podrían tener sus existencias reducidas en más del 300% que se mantendría la misma eficiencia en relación a la atención de la demanda. Contribuciones del Estudio: El presente trabajo contribuye con la literatura de controles gerenciales, apuntando técnicas de investigación operacional para gestión de stocks. Además, trae una valiosa contribución a pequeñas empresas del sector farmacéutico, auxiliándolas en la utilización del uso de herramientas estadísticas simples para mejorar la eficiencia de la inversión en stock, y consecuentemente el desempeño financiero.Objetivo: O objetivo do estudo é aplicar a Simulação de Monte Carlo (SMC) para o gerenciamento dos estoques em uma farmácia de pequeno porte.
