“…Valentine and Gray(2001) went further and compared port efficiency to determine a relationship between ownership and organizational structure with efficiency. Ryoo(2006) focused on the efficiency measurement of major container terminals in Asia and container terminal operations in Busan and Kwangyang ports (Ryoo, 2005 (Charnes et al, 1978) and have multiple inputs and multiple outputs. Among the advantages of using DEA, it should be mentioned that this methodology does not impose any functional form to the production function or on the shape of returns to scale and that it enables dealing with multiple output process (Park, 2006).…”

“…Technical efficiency allows outputs to vary unproportionally with only a marginal increase in inputs. This type of efficiency is calculated by a DEA-BCC with variables return to scale (Park et al, 2007;Ryoo, 2005). Neutralizing the scale inefficiencies, the relative differences between smaller and bigger ports are removed and purely operational efficiency is reflected.…”

: Recently, the fierce competitions in the shipping industry and the global economic downturn have heavily influenced ports' operational strategies. In order for port authorities to remain competitive at an international level and to provide more accurate information to develop National policies, ports are required to analyse and improve operations' efficiency. In this paper, the efficiency of 19 Italian ports in 2013, handling different types of cargoes, is assessed through the application of Data Envelopment Analysis (DEA), with constant return to scale (CRS) and variable return to scale (VRS). The purpose of this study is to analyze the efficiency of Italian ports and evaluate whether differences in size and specialization of each port (or cargo handled) are directly correlated with ports' efficiency.

“…Due to an increase in container cargo transportation each year, research [16][17][18] proposes a sub-hub system that can help to lower congestion in the ports. The sub-hub port has a much smaller container throughput, but it can help to solve the demand imbalance and port congestion problems [19][20][21][22].…”

Adriatic Sea Hub Ports Feeder Service Optimization Using Multi-Criteria Decision-Making Methods

et al. 2021

From a scientific viewpoint, as well as from the perspective of navigation practice, it is clear that the Adriatic Sea feeder service is relatively underdeveloped. Hence, the objective of this study is to suggest a model for selecting the hub port and to optimize the network of seaports engaged in the feeder service. Accordingly, an appropriate hub port has been identified through the methods of multi-criteria decision making and expert assessment, and the optimum shipping route has been calculated by applying the travelling salesman algorithm (TSA). In order to analyze whether there is a possibility of obtaining better optimization results, an integration of a sub-hub port system is suggested. Optimization has been achieved by applying a minimum spanning tree algorithm (MST) and a combination of these algorithms. The proposed methodology for selecting the hub port, sub-hub port and optimizing the feeder network can be implemented globally. The practical application of the achieved model would result in cost minimization, owing to shorter shipping routes or a combination of different transportation means (feeders).
