At the beginning of the 21 st century the business environment may be described as that of global competition among large enterprises. It foliows that the need for successful implementation of corporate strategies has tumed the effective use of information systems into a differentiating factor. Within this framework, investments in real assets characteristic of capital intensive industry, such as Inventories of Materials and Equipments, demand proficiency in management, in order to assure the profitability of a business. In the Petroleum Industry the logistics costs are the main spend category, accounting for approximately 43% of total costs, 37% of which due to investments in Materiais and Equipments for Maintenance, Repairs and Operations MRO. Therefore, the analysis of the Costs of Inventories becomes relevant to evaluate its impact on the profitability of that industry. Starting from a Strategic Modei ofProfits, created by Douglas M. Lambert and James R. Stock, a model was deveioped to evaluate the impact of the Inventories on ROA (Return on Assets) and on ROE (Return on Equity). This model became the basis of the Program of Reduction of the Inventories Costs, which was applied to 27 Units of Petrobrás in Brazil and one Unit abroad: Colombia. The experience obtained was used to elaborate this Case Study in which, through the application of that Model, the results were evaluated from 1999 to 2003 in the Brazilian units, and in 2003 in Colombia. The anaiysis ofthe application ofthe Model, through simulation, resulted in an increase of up to 36% of ROA and an increase of 18% of ROE per year. On the other hand, the effective application of the Model resulted in significant improvements of key indicators, such as Inventory Level, Inventory Turnover, Inventory over Total Revenue (%), reaching the performance of Petrobrás the benchmarking levei of the international petroleum industry, according to CAPS (Center for Advanced Purchasing Studies), University of Arizona. Key words: Logistics Costs, Inventory Costs, Reduction of Inventories and Impact on the business profitability.
