Collection description

Modelling worldwide container network is a key topic in assessing the effects of strategic and operational decisions on the port systems development. In this respect, the present thesis proposed an innovative approach to deal with some of the main issues highlighted in the literature so far. Firstly, the research proposes a methodology to deal with non-additivity of key performance variables in the rail freight supply model. The innovative procedure is applied to the railway intermodal transport in Italy, to show the feasibility of the approach. Secondly, this study developed an innovative representation of the maritime container service network based on the hyperpath approach, proving the viability of a worldwide application. Also, the applicability of some centrality metrics commonly used to analyse transport networks, is discussed. As a result, a new formulation of the beetweenness centrality suitable for hypergraphs is proposed, allowing a more realistic analysis of worldwide ports. Furthermore, an in-depth assessment of liner container services on a global scale has been carried out, including shipping market concentration analyses (by adapting the Herfindahl-Hirschman Index - HHI). This yields interesting insights on market positioning of shipping companies and ocean alliances across ports and trade regions. Finally, this work assesses the issue concerning the estimation of port-to-port freight flows through the application of the well-known GLS approach commonly used to estimate o-d flows from traffic measurements.
