Multi-criteria evaluation of vessel traffic for port assessment: A case study of the Port of Rotterdam

Abstract

Vessel traffic is a key element determining port safety and capacity. The growth of port calls and cargo can have implications in port operations. Decision makers need to take decisions to anticipate any future capacity drop or increase in nautical risks. In this research, a multi-criteria decision making methodology is developed to evaluate the trade-off between safety and capacity of vessel traffic in ports, as well as other assessment indicators. The methodology first identifies the most relevant risk and capacity assessment criteria and the input required. A simulation model is used to calculate the criteria for a variety of different scenarios. The outcome results for the criteria from the simulations are used into a decision-making method that includes unknown decision makers’ preferences. The use of this methodology provides the best scenario for port vessel traffic, when strategic and operational decisions should be taken, and it can be used as a framework for port assessment by decision makers for future changes in traffic management strategies or changes in the port infrastructure, such as port expansions.
