Grilo, J. and Dias, J.C.Q. (2015), “Performance evaluation using data envelopment analysis: The case of Portuguese general cargo terminals”, Maritime Technology and Engineering, Guedes Soares, C. & Santos T.A. (Eds.), Taylor & Francis Group, London, UK, pp. 37-44

This paper aims to assess the performance of the main Portuguese terminals that handle general cargo. The method adopted for the performance evaluation is the Data Envelopment Analysis (DEA) that compares the terminals between each other by benchmarking and determines the existent inefficiencies of the system. It was chosen to optimize the resources (infrastructures, equipment etc) in relation to the fixed yearly values of cargo throughput of each terminal. The variables were selected with the aid of the Compensatory Method of Single Standardization, which determines the variables to be used by an efficiency index. The re-sults demonstrate that the terminals have different performance levels and different patterns of efficiency. Fur-thermore the most efficient terminals are identified for this type of cargo, on the Portuguese ports, and issues are identified which can improve the overall efficiency.
