The port system is a key element for the macroeconomic development of its area of influence. The performance evaluation of the port sector becomes fundamental to the monitoring and improvement ofthe activities of this sector aiming at accomplishing efficiency. The Data Envelopment Analysis– DEA is a method based on mathematic programming which analyzes, based on the inputs and outputs utilized in a certain process, the efficiency of a set of Decision Making Units – DMU. The present work has as a goal to elaborate and analyze models for the efficiency measuring of the ports in Brazil’s northwest in 2006, adopting the DEA method. The variables selection was done with the aid of the Compensatory method ofNormalization (Single Parameter), which determines the variables to be utilized through index S that depends on the average efficiency (causal relation) and the quantity of DMU in the frontier (discrimination power). The facilities of containers and solid bulks of the main ports in northwest were analyzed. This model was applied through the programs SIADv3.0 to the sixteen ports of the region above mentioned, being analyzed through the type of load (container and solid bulk). The results obtained through the analysis accomplished verified that among the sixteen ports analyzed in Northwest, fourteen have precarious facilities, except for Salvador port, concerning the containers turnover, and “São Luís1” terminal, when it comes to the solid bulks turnover. The variables berth and draught in the models analyzed were the ones which obtained highestvalues concerning weight and the ones which were present in different scenarios. In other words, the efficiency analyzed in this study has a strong relation to the variables mentioned. The obtaining of the port efficiency executed by the type of load helps in the medium and long-term planning, so that it organizes the ports toincrease the timetable turnover and the loads turnover, contributing to the efficiency of the terminals. The Data Envelopment Analysis has proved to be a method which can contribute to the decision makers for analysis, management and planning of the port sector.
