(author)The aim of this paper is to provide a conceptual basis for the systematic treatment of uncertainty in model-based decision support activities such as policy analysis, integrated assessment and risk assessment. It focuses on the uncertainty perceived from the point of view of those providing information to support policy decisions (i.e., the...journal article 2003

Marchau, V. (author), Walker, W. (author), Van Duin, R. (author)Urban transport is facing an increasing number of problems. Innovative technological solutions have been proposed for many of these problems. The implementation of these solutions, however, is surrounded by many uncertainties—for example, future relevant developments for urban transport demand and supply, the possible consequences of these...journal article 2009

Mouter, N. (author), Holleman, M. (author), Calvert, S.C. (author), Annema, J.A. (author)An important limitation of Cost-Benefit Analysis (CBA) is the inherent uncertainty in estimations of future welfare effects. In this paper, we argue that consideration of the ‘price-quality’ dilemma and the ‘communication’ dilemma is useful to explain and improve the handling of uncertainty in CBA. The ‘price-quality’ dilemma refers to the trade...journal article 2015

Melese, Y.G. (author), Heijnen, P.W. (author), Stikkelman, R.M. (author)Development of networked energy infrastructures (like gas pipe networks), generally requires a significant amount of capital investment under resources, market and institutional uncertainties. Several independent suppliers and consumers are to be connected into these networks. However, the actual commitment of these parties and the capacities...journal article 2014

Bijlsma, R.M. (author), Bots, P.W.G. (author), Wolters, H.A. (author), Hoekstra, A.Y. (author)Stakeholder participation is advocated widely, but there is little structured, empirical research into its influence on policy development. We aim to further the insight into the characteristics of participatory policy development by comparing it to expert-based policy development for the same case. We describe the process of problem framing and...journal article 2011

Kwakkel, J.H. (author), Walker, W.E. (author), Marchau, V.A.W.J. (author)Airport Strategic Planning (ASP) focuses on the development of plans for the long-term development of an airport. The dominant approach for ASP is Airport Master Planning (AMP). The goal of AMP is to provide a detailed blueprint for how the airport should look in the future, and how it can get there. Since a Master Plan is a static detailed...journal article 2010

Haasnoot, M. (author), Kwakkel, J.H. (author), Walker, W.E. (author), Ter Maat, J. (author)A new paradigm for planning under conditions of deep uncertainty has emerged in the literature. According to this paradigm, a planner should create a strategic vision of the future, commit to short-term actions, and establish a framework to guide future actions. A plan that embodies these ideas allows for its dynamic adaptation over time to meet...journal article 2013

Zarifsanayei, Amin Reza (author), Antolínez, José A. Á. (author), Etemad-Shahidi, Amir (author), Cartwright, Nick (author), Strauss, Darrell (author), Lemos, Gil (author)This study quantifies the uncertainties in the projected changes in potential longshore sediment transport (LST) rates along a non-straight coastline. Four main sources of uncertainty, including the choice of emission scenarios, Global Circulation Model-driven offshore wave datasets (GCM-Ws), LST models, and their non-linear interactions were...journal article 2022

Huber, Gerhard (author), Bogenberger, Klaus (author), van Lint, J.W.C. (author)The comparably low driving ranges of battery electric vehicles (BEV) cause time-consuming recharging stops if long distances have to be covered. Thus, navigation systems not only have to compute routes leading from the BEV's current position to the destination, but also to plan recharging stops. This type of routing problem is often modeled...journal article 2022

Scott, Michael J. (author), Verhagen, W.J.C. (author), Bieber, M.T. (author), Marzocca, Pier (author)In recent decades, the increased use of sensor technologies, as well as the increase in digitalisation of aircraft sustainment and operations, have enabled capabilities to detect, diagnose, and predict the health of aircraft structures, systems, and components. Predictive maintenance and closely related concepts, such as prognostics and health...journal article 2022

Røsok, O.P. (author), de Bruijne, M.L.C. (author), Veeneman, Wijnand (author)The interdependencies between infrastructures are growing. Engineering decision making that earlier was largely confined to a specific sector now requires more and more understanding of how systems interact: a system-of-systems perspective. The article analyzes the effect of that added complexity in a single case study in de Zuid-As, Amsterdam,...journal article 2023

van den Boomen, M. (author), Van der Meulen, Sjoerd (author), Van Ekris, Jonathan (author), Spanjers, Roel (author), Ten Voorde, Olle (author), Mulder, Janwin (author), Blommaart, Peter (author)<br/>The port of Rotterdam is the largest seaport in Europe. To maintain its position, the harbor will have to anticipate global transitions such as transferring to sustainable energy. Hydrogen is seen as a promising energy carrier; however, future demand is uncertain. The current research investigates decision making under uncertainty and...journal article 2021

Song, Jingkuan (author), Guo, Yuyu (author), Gao, Lianli (author), Li, Xuelong (author), Hanjalic, A. (author), Shen, Heng Tao (author)Video captioning, in essential, is a complex natural process, which is affected by various uncertainties stemming from video content, subjective judgment, and so on. In this paper, we build on the recent progress in using encoder-decoder framework for video captioning and address what we find to be a critical deficiency of the existing...journal article 2018

Ertsen, M.W. (author)Dealing with uncertainty is key in socio-hydrological analysis. As such, thinking through what uncertainties mean for whom and when is key. This discussion contribution introduces three issues related to defining uncertainties. The first issue deals with the problem of defining uncertainty as a given external reality. The second issue deals with...journal article 2018

Zwaginga, J.J. (author), Lagemann, Benjamin (author), Erikstad, Stein Ove (author), Pruyn, J.F.J. (author)Shipowners need to prepare for low-emission fuel alternatives to meet the IMO 2050 goals. This is a complex problem due to conflicting objectives and a high degree of uncertainty. To help navigate this problem, this paper investigates how methods that take uncertainty into account, like robust optimization and stochastic optimization, could be...journal article 2024

Bamber, J. L. (author), Oppenheimer, M. (author), Kopp, R. E. (author), Aspinall, W. P. (author), Cooke, R.M. (author)The ice sheets covering Antarctica and Greenland present the greatest uncertainty in, and largest potential contribution to, future sea level rise. The uncertainty arises from a paucity of suitable observations covering the full range of ice sheet behaviors, incomplete understanding of the influences of diverse processes, and limitations in...journal article 2022

Refsgaard, Jens Christian (author), Mai, Juliane (author), Hrachowitz, M. (author), Jain, Sharad K. (author), Stisen, Simon (author)Catchment modelling has undergone tremendous developments during the past decades. In the 1970s, the focus was on simulation of catchment runoff with process descriptions and data inputs being lumped to the catchment scale. Later developments included spatially distributed models allowing data inputs and hydrological processes to be simulated at...journal article 2023
