Analysis of technical efficiency and eco-efficiency in container terminals

摘要

This paper shows the results of performance assessments of 15 container terminals in Brazil, considering both eco-efficiency and technical efficiency measures. It was necessary to determine indicators and measures in order to apply a multi-criteria decision-making technique known as grey relational analysis, to aggregate values that have different scales and units of measurement and to rank the container terminals according to their performance levels. It was possible to determine that higher performance levels in eco-efficiency do not, necessarily, mean that higher technical performance is taking place. Variations in the weights assigned to technical efficiency and eco-efficiency measures might influence the performance ranking of the terminals.
