dc.description.abstractAs a result of new market conditions, influenced by privatizations, crises and newcomers, the steel industry has sought the improvement of its management process, through production maximization and input optimization. In this context this dissertation aims to analyze the determining factors for the efficiency of Gerdau’s mini-mills, located in different countries of South and North America. This is a descriptive and exploratory study, with quantitative approach, based on data from the years 2009 and 2010. Case study was the procedure adopted, including 24 units of analysis. With the use of the Data Envelopment Analysis (DEA) methodology it was possible to measure the technical and economic efficiency of the selected mills, as well as to identify the benchmarks. The main findings show that the Brazilian mills are the most technically efficient; the relevant factors behind these results are their productivity in the safety incident input and low equipment downtime. A group of American mills was also considered technically efficient due to high productivity in the operational assets and labor inputs. By replacing the inputs for their relative prices, it becomes evident the superiority of the Brazilian mills in terms of result, which were more productive in the three economic efficiency analysis inputs: operational assets, administrative expenditure and costs of steelmaking.en
