Efficiency analysis of Brazilian public container terminals
Cargo handling in private and public ports is one of the main activities in trade logistics. A different adaptation on container operations is required, as it plays a different role in terms of performance in port operations in Brazil. The use of data envelopment analysis (DEA) is applied to analyze the relative efficiency in terms of container operations in the Brazilian port terminals. The objective pursued was to identify the different performances of container handling in Brazilian ports and to show possible improvements for less effective ports. The research points out to the changes required in some ports in Brazil in relation to their inefficiencies.
Efficiency Container Ports in Brazil: A Dea and FDH Approach
The Central European Review of Economics and Management
Aim: This study aims to evaluate the technical efficiency of 44 Brazilian port terminals that handled containers in 2016. The evaluation will first proceed by identifying the main benchmarks. It will then provide an analysis of variables that may have an effect on technical efficiency as well as the nature of their relationship with the latter--namely: container movement and specialized terminals. Design / Research methods: In this work we apply the techniques of Data Envelopment Analysis and Free Disposal Hull. Output-oriented models were constructed, using three inputs - berth depth, berth length and number of berths, and three outputs - number of containers handled, medium board measured in container handled per hour of mooring, and medium consignment rate measured in container throughput per ship. Conclusions / findings: The main results show that half of the terminals have an inefficient infrastructure, with capacity larger than necessary to meet current demand for transportati...
The article presents a method for evaluating the efficiency of port container terminals. The research was conducted for nine European terminals which use different handling technologies. The terminals have been divided due to the level of automation of transport processes. In the efficiency research DEA (Data Envelopment Analysis) method is applied, that was previously used in studies of the relative productivity in the industry. This method allows you to multicriteria process analysis based on the properly selected production system model processing input parameters on output. Conclusions from analysis can be a ground for making a decision on organizational or investment issues.

The objective of this paper is to analyse the relative efficiency of operations in container terminals of Mercosur in the years of 2002, 2003 and 2004, using the data envelopment analysis technique in a model BCC, with five inputs (number of cranes, number of berths, number of employees, terminal area, amount of yard equipment) and two outputs (TEUs handled and average number of containers handled per hour/ship). The units of analysis are 15 Brazilian, six Argentinean and two Uruguayan container terminals. The analysis shows that 60% of the terminals were efficient in the 3-year period. Benchmarking analysis of Zarate, Rio Cubatão and Teconvi revealed that those terminals served as reference for inefficient terminals more often than other terminals.
Environmental efficiency for a cross-section of Spanish port authorities
Transportation Research Part D-transport and Environment, 2019
Shipping has well-documented environmental impacts, among which are greenhouse gas emissions that contribute to climate change and global warming. Measurement of the possibility of ports to reduce emissions by operating more efficiently provides important information for policymakers. In this study we estimate environmental efficiency for a cross section of 28 Spanish Port Authorities observed in 2016 using an output-oriented directional distance frontier with a 'bad output', carbon dioxide (CO 2) emissions. We use the non-parametric mathematical programming technique of Data Envelopment Analysis (DEA) to estimate the frontier. Our novel dataset includes information on CO 2 emissions obtained for these Spanish Port Authorities using the fleet activity-based emission estimation (bottom-up) methodology. Using ships berthing as output, if all port authorities had been environmentally efficient in providing their services, CO 2 emission could have been reduced to an average of 63% of their actual observed levels with a simultaneous increase in good output. When using cargo and passenger traffic as output in order to control for ship characteristics through the output mix, we find that reductions of emissions to 82% of observed levels could be achieved with simultaneous increases in outputs, and reductions to 72 of existing levels if good outputs remain constant. 2013 in its Strategy101 consisting of three steps: monitoring, reporting and verification of CO 2 emissions from large ships using EU
International Journal of Business Performance Management, 2012
The purpose of this paper is to assess the performance of the main Iberian container terminals in terms of efficiency. In this research are used multiple case studies to investigate the performance of ten Iberian terminals of different sizes and with different characteristics to rank them in terms of efficiency applying the recursive DEA with Kohonen Self-Organisation Maps (KSOM). The results evidence that the container terminals do have different performance levels and they present different patterns of efficiency. Moreover, the findings allow identifying the better competitor in this industry. This research contributes for policy-makers, seaport authorities, dealers, and researchers to support their decision making and to help define future decision policies in seaport industry. The results are very opportune in actual debate about the seaport industry competitiveness and how the seaports could improve their efficiency.
A Survey of Data Envelopment Analysis in Container Terminals
Mersin University Journal of Maritime Faculty, 2020
In recent years, Data Envelopment Analysis (DEA) technique has been used quite frequently in determining container terminal efficiency. When the studies reviewed, conducted on the subject in the recent past, it is seen that the details such as the parameter on which the activity model focuses, sample selection, sample size and input-output selection have not yet been clarified enough, additionally, problems and confusion are encountered in practice. In this study, a critical analysis was carried out regarding the determinations in the use of the DEA technique, which is frequently used in the measurement of container terminal efficiency, and on which issues should be considered in order to establish the model better. In the consequences of the study, it was seen that data accessibility was an obstacle to reaching more robust results in efficiency analysis. It is very important to make evaluations between ports that are close to each other in terms of regional or infrastructure, demand and technological development in order to obtain more reliable and consistent results. Moreover, future studies should consider reliable inputs such as the number of equipment in the terminal that divided by two group, the terminal area, maximum depth, pier length.

Cabotage appears as an option among the transportation modes combining reliability and energy efficiency in order to maximize profits and reduce pollution. In this context, the study aims to examine the effectiveness of five terminals for three years. They operate with containerized cargo transport in cabotage in order to identify which terminal is more efficient. RESUMO A crescente taxa de produção brasileira exige, a cada dia, um melhor escoamento de produtos e matérias primas. A Cabotagem surge como opção entre os modais de transportes aliando confiabilidade e eficiência energética de forma a maximizar os lucros e diminuir a poluição. Nesse contexto, o trabalho pretende analisar a eficiência de cinco terminais, durante três anos, que operam com transporte de carga conteinerizada na cabotagem, a fim de identificar qual terminal é mais eficiente.
Relative efficiencies of seaport container terminals: a DEA perspective
International Journal of Integrated Supply Management, 2005
With the rapid growth of containerisation in world maritime trade, container terminals have undertaken heavier tasks and more important roles to achieve better service quality and agility in the supply chain. Container terminals operate in a fierce competitive environment of international character. Their rivals are their neighbouring ports/seaport terminals, and/or similar facilities within their hinterlands. To accomplish the competitive advantage in global shipping, port managers have undertaken more effort continuously to improve their terminal productivity. However, to sustain competition in their favour it is also essential for managers to undertake benchmarking with the competing terminals. The aim of this paper is to guide port managers to benchmark their organisational performances with their competitors; thereby making necessary arrangements to use their resources more effectively. In this connection, 10 seaport terminals lyingon the coast of the Sea of Marmara and the Mediterranean rim are taken as decision-making units and data envelopment analysis (DEA) is applied to measure and evaluate their relative performances.
Efficiency and productivity of container terminals in Brazilian ports (2008–2017)
Utilities Policy, 2019
After the economic recession in which Brazil was immersed during the years 2015 and 2016, signs of recovery are perceived through port activity. The objective of this research is to analyze the efficiency and productivity of 20 container terminals in Brazilian ports for the 2008 to 2017 period. The methodology used is stochastic frontier analysis and operational port indicators including variables such as the frequency of calls. The most significant findings obtained from the efficiency analysis reveal that private terminal operators are more efficient. The average technical efficiency level was 0.66 in 2008 and in the last year 0.51.
