Balancing connectivity and reliability in the schedule design of airlines by buffer scheduling: a Proof of Concept: Research on how to trade off passenger connections and delays in hub-and-spoke airline schedules

In the last decades, the environmental impact of aviation has been an emerging topic of discussion worldwide. With an expected CO2 emission increase of 21% by 2040 for air traffic, there is an urgency to reduce the negative impact on the environment. On top of that, the number of passengers is expected to double within the next 20 years. This...

Uncertainty in Long-Term Grid Planning: Approaching Transmission Expansion Planning through the Framework of Decision Making under Deep Uncertainty

Motivations for sustainability are initiating an energy transition that is changing the European energy domain. The transition effectuated the adaptation of large volumes of wind and solar based generation capacity. The intermittent power-output of these Variable Renewable Energy Sources challenges the balancing operation of the electricity...

Riverine flood risk screening with a simple network-based approach: A proof of concept in the Ganghes-Brahmaputra basin

Floods cause major problems around the world. Over 35 million people were affected by floods in 2018. They have a growing worldwide impact on life and property. Changes in climate conditions lead to unanticipated variations in glacial runoffs, snowmelt and precipitation, which all significantly changing river flows. An imbalance in river network...

Towards Resilient Urban Stormwater Management in a Tsunami Reconstruction: A Scenario Discovery Study on Ötsuchi Town, Japan

In the face of climate change, urban stormwater management practices are subject to an uncertain context. More frequent and extreme rainfall events are expected in many urban areas. The extent how climate change will affect weather patterns is however uncertain. This challenges contemporary stormwater management practices. A post-disaster...

Uncertainty-Driven Policies for Resource Allocation in Epidemics Response

Humanitarians and global health actors come to the aid of many people every year, with the aim of preventing disease, increasing wellbeing, and providing (medical) aid to those suffering from disease. One of the contexts in which they operate is that of an epidemic. An epidemic is dynamic by nature and provides a complex and evolving environment...

System effects of cross-border transmission capacity and seasonal storage on the future Dutch power system

The Dutch government aims at 70% of electricity production from renewable energy sources in 2030 in order to reach a CO2 emission reduction of 49% as compared to 1990 levels. With the increasing share of variable renewables in the European power system, it becomes increasingly more important to find a way to deal with generation volatility. The...

Multiple co-existing ontologies in the paraná delta: An action-research approach to the case of the Paraná Delta, Argentina

Adaptive delta management (ADM) deals with making flexible and robust plans in the uncertain environment of deltas. ADM receives increasing attention to be applied globally, including in Argentina. In this research, I have studied how modelling can assist ADM in Argentina through action research by applying various participatory methods like...

Uncertainty in electrified industrial systems: Towards a method for the identification and exploration of uncertain factors

Uncertainty has an obstructing role in the decision-making of electrification investments for industrial actors. Future research by analysts is required to explore the potential of electrified industrial systems in their uncertain environments. In order to enable research to uncertainty in electrified industrial systems, the identification and...

Exploring the performance and ethicality of smart charging systems: An explorative agent-based modeling research on the performance, system-usage, and ethical value fulfilment of decentralised and centralised smart charging systems

Increased Feed-in of renewable energy sources and an increase of sales of electric vehicles (EVs) complicate balancing of demand and supply. EVs are considered core enablers for dealing with intermittency due to their storage potential. This does however require that these EVs are charged according to smart charging protocols, which is a vehicle...

Investigation of the evolution of the irrigation system in ancient Mesopotamia using a hydraulic model

In this study a simplified model of the rivers Tigris and Euphrates during the Uruk period (3500-3100 B.C.) was created in order to define the hydraulic behaviour of the rivers in ancient Mesopotamia. The model was used to test the effect of a number of factors on the water-level of the river system. Especially, the role of the development of...
