Policy Analysis of Safe Vertical Manoeuvring using Reinforcement Learning: Identifying when to Act and when to stay Idle

The number of unmanned aircraft operating in the airspace is expected to grow exponentially during the next decades. This will likely lead to traffic densities that are higher than those currently observed in civil and general aviation, and might require both a different airspace structure compared to conventional aviation, as well as different...

Complex Coastal Systems: Transdisciplinary learning on international case studies

The transdisciplinary research synthesised in this book represents an endeavour by a group of coastal researchers and policy analysts to learn from a cross-comparison of seven international case studies on tidal inlet or estuary mouth management situations, located in South Africa, Sri Lanka, California, Suriname, Ireland and the Netherlands....

Modelling Uncertainty: Developing and Using Simulation Models for Exploring the Consequences of Deep Uncertainty in Complex Problems

Simulation models are increasingly used for exploring the consequences of deep uncertainty in complex societal issues. The complexity of societal grand challenges, often characterised by the interrelatedness of different elements in the systems underlying these challenges, often renders mental simulation impossible, necessitating the use of...

The Participation Triangle: Involving Generation Y in energy strategy

The liberalization of the Dutch energy market has led to a change of relation between energy companies and their customers. At the same time, the Dutch energy policy expects energy companies to contribute to an energy supply that is cleaner, smarter and more varied, and available at any time at affordable prices. The situation since the...

Integrative approach to regional water schemes in South Africa

This article explores the use of a System Dynamics model as a boundary object in a case study regarding decision-making on water scarcity in South Africa. The model integrates expertise from the hydrological and ecological sciences with socio-economic information for a specific area, the Mossel Bay region. The model proved to be adaptable to...

A critical approach to some new ideas about the Dutch flood risk system

Decisions on measures to improve a flood risk system are in part supported by general ideas about how the system works and should work. After the completion of the Dutch Delta Works around 1990, such new ideas regarding flood risk emerged. Some of these may be appealing at first, but appear debatable after a closer look. In this paper, fourteen...
