The discrete event simulation is one of the most used techniques in operational research area. It is a support decision technique, in which the search for problem solving is done by analyzing a computer model that describes the behavior of the system under study. Applications of this technique are found in several areas and have very significant results, especially for manufacturing and logistics industry. This paper presents the construction of a simulation discrete event model in the computer system Arena® to analyze a part of the supply chain of a service company, aiming to help define the minimum stock level of material in a distribution center. The adopted simulation approach considers the material as the main entity, and it represents the volume of stock in the links in the chain as lines on the template simulation modules, which simplifies the modeling and gives a uniqueness of character to the proposal. As a result, you can determine the best inventory security levels of in different stochastic demand scenarios with high variability, considering pre-established service levels and uncertainty in delivering the material.
