One of the main concerns of organizations is the improvement of production processes. To stay on the market they need to be competitive and they must permanently improve their processes. The objective of this work was to analyze, through computer simulation techniques, the production process of a small clothing company located in the city of Aparecida de Goiânia, Goiás. The Arena® software was used to evaluate the mean time that the Skin bras remained in a queue at each production stage, as well as the average time spent performing the task at each stage. It is scientific, quantitative and qualitative research. According to its objectives, it presents a descriptive and explanatory character, aiming to deepen the knowledge of the reality, using the case study for data collection. Two scenarios were created for the company, for comparison purposes with the current scenario. The conclusion reached was that, currently, the production of bras in the company has a good flow; however, it is necessary be careful with the formation of extensive queues at the cutting and preparation sectors.
