This dissertation addresses the initiatives in the inventory analysis of a fuel distribution company in Brazil. It tells about the continuous search for the stateof-art in terms of logistics modeling and how to deal with several of trade-offs existing in the supply chain. The main objective is to present how this model was created using an Advanced Planning System, how it helped to dimension the safety stocks and finally, what actions need to be taken in order to ensure that a ripening process that adds value to the company can be developed. It still addresses the growing importance of Supply Chain Management software and how the use of these technologies can be useful to tackle inventory analysis problems using an action research approach. This work provided powerful insights like the reallocation of safety stocks according to the transportation times and demand profiles, the potential economy that a more accurate demand forecast can bring to the company and even how investments in infrastructure can be driven by the new comprehension of the inventory dynamics. The new solution proposed implies a reduction of 17.8 percent in the inventory levels.
