A port simulation model as a permanent decision instrument

Access to the port of Antwerp in Belgium is provided through locks connecti ng the river with docks. The decision to build a container quay on the rive r, outside the port, will hinder through traffic. A simulation model is bui lt to investigate the hindrance of the river quay. Detailed modelling of ma ritime traffic on the river, including navigation logic, tides and lock pla nning, are included. Simulation experiments are run based both on current r eal-life measurements and on traffic forecasts. The model is built and impl emented in such a way that it is reusable and extendible for future decisio ns on infrastructure improvements or maintenance projects.
