Dimensionamento de estoques em uma farmácia por meio da pesquisa operacional

Abstract

With the increasing competitiveness of the pharmaceutical sector, it is necessary for companies to seek to optimize their gains, with inventory management being necessary to serve customers, ensuring good billing, and reducing associated costs. The present work was developed in a pharmacy, located in the interior of the State of Rio Grande do Sul, focusing on the cosmetics sector. The main problems that motivated the accomplishment of the study were the loss of products due to its validity or obsolescence and the need to determine the amount necessary for the company to keep in its stock, in order to meet the existing demand. For this, an analysis of the company's daily demand for enamels was carried out and a study on the costs of inventories, their types and their main characteristics. Also a study on mathematical models and Operations Research, in order to develop a mathematical model of Linear Programming with the selected products to maximize the company's revenue. For the selection of products, Pareto charts were used, seeking to know those with the most representativeness in the sales volume. As a result, a proposal of quantities in stock is presented for the most sought after nail polishes by customers and a study on the demands of these products, which were unknown by the manager. Finally, it is expected to contribute to solving this current problem of the company, so that in the future it can be applied in other sectors.
