van Staveren, D. (author), Arkesteijn, M.H. (author), den Heijer, A.C. (author)Purpose: Corporate real estate management (CREM) is complex due to an increasing number of real estate (RE) added values and the tensions between them. RE managers are faced with trade-offs: to choose a higher performance for one added value at the cost of another. CREM research mainly deals with trade-offs in a hypothetical sense, without...journal article 2024

(author)Introduction: The challenge of the energy transition in the built environment has, in recent years, been exacerbated by rising awareness of the material resource limitations we face on the path towards sustainable development. In this context the concepts of Circular Economy (CE) and Product-Service Systems (PSS) have emerged as potentially...journal article 2023

den Heijer, F. (author), Rijke, Jeroen (author), Bosch-Rekveldt, M.G.C. (author), de Leeuw, Annemargreet (author), Barciela Rial, M. (author)Flood defences are in practice often multi-used, multi-managed and multi-financed. Flood defence asset management contains technical, organizational and spatial complex issues involving multiple organizations. In the literature, little attention has been given to the conditions for successful cooperation between organizations in flood defence...journal article 2023

den Heijer, F. (author), Podt, Maarten (author), Bosch-Rekveldt, M.G.C. (author), de Leeuw, Annemargreet (author), Rijke, Jeroen (author)Flood defences are often situated in public spaces and are mostly multi-functional, multi-financed and multi-managed. Cooperation in flood defence asset management is important because roles and responsibilities are fragmented within and between organisations. This complex context calls for mutual understanding from responsible role-holders....journal article 2023

den Heijer, F. (author), Kok, M. (author)A system of dikes in flood-prone areas continuously requires measures to mitigate changes such as ageing and climate change. Planning costly measures requires proper insight into system risk effects. Especially in a riverine dike system, the risk contributions of individual assets to the system flood risks are not independent, because...journal article 2023

den Heijer, Xander (author)The Dutch healthcare system has reached a point of no return. Or we drastically change our behaviour and the way healthcare is delivered. Or we keep on going as we do, and the costs will be unbearable, pressure on the workers increases and access to care will become something for the happy few. To contribute to changing the Dutch healthcare...master thesis 2022

Rymarzak, M. (author), den Heijer, A.C. (author), Arkesteijn, M.H. (author), Du Preez, M. (author)Campus decision makers are increasingly expected to adopt ‘campus innovations’ (affecting real estate and different facilities), not only from the market and demand-led (external campus innovations), but also developed by the university's own scientists (internal campus innovations). The adoption of the latter can be driven and hindered by...journal article 2022

den Heijer, F. (author), Kok, M. (author)Dikes are an effective flood risk reduction measure in deltaic areas. Present risk analyses consist often of decoupled calculations of probabilities of dike failure and calculation of consequences of flooding given dike failure. However, the flood defense design determines not only the probability of failure, but influences the consequences...journal article 2022

den Heijer, Remco (author)Does a convolutional neural network (CNN) always have to be deep to learn a task? This is an important question as deeper networks are generally harder to train. We trained shallow and deep CNNs and evaluated their performance on simple regression tasks, such as computing the mean pixel value of an image. For these simple tasks we show that...bachelor thesis 2021
