Yenigül, N.B. (author)Landfills represent a wide-spread and significant threat to groundwater quality. In this thesis a methodology was developed for the design of optimal groundwater moni-toring system design at landfill sites under conditions of uncertainty. First a decision analysis approach was presented for optimal design of groundwater monitoring sys-tems under...doctoral thesis 2006

Mukolwe, M.M. (author)Computers are increasingly used in the simulation of natural phenomena such as floods. However, these simulations are based on numerical approximations of equations formalizing our conceptual understanding of flood flows. Thus, model results are intrinsically subject to uncertainty and the use of probabilistic approaches seems more appropriate....doctoral thesis 2016

Liang, F. (author)It is our choices that make us who we are. To lead a better life, we have to make better decisions. Nowadays, decisions are increasingly made in complex contexts, in a host of different application domains. Because of that, we need more reliable decision analysis methodologies to improve our decisions. The ability to deal with multi...doctoral thesis 2021

Leijten, M. (author)Complex underground infrastructure construction projects tend to develop in a state of “bounded manageability”. Various types of uncertainties are inherent to these projects and put the project manager in front of serious challenges, risking budget overruns, delays and sometimes even technical failure. Managing such a project is a matter of...doctoral thesis 2017

Operational flood forecasting, warning and response for multi-scale flood risks in developing citiesRogelis Prada, M.C. (author)Flood early warning systems are recognized as one of the most effective flood risk management instruments when correctly embedded in comprehensive flood risk management strategies and policies. Many efforts around the world are being put in place to advance the components that determine the effectiveness of a flood early warning system. The aim...doctoral thesis 2016

Halim, R.A. (author)Uncertainties in future global trade flows due to changes in trade agreements, transport technologies or sustainability policies, will affect the patterns of global freight transport and, as a consequence, also affect the demand for major freight transport infrastructures such as ports and hinterland networks. Policy makers face the challenge of...doctoral thesis 2017

van den Boomen, M. (author)Ageing infrastructures and shortage of financing induce the need for optimising public infrastructure replacements. From an economic perspective, classical net present value comparison is traditionally the method of choice to decide on investments and replacements. The current research observes that typical infrastructure related features make...doctoral thesis 2020

Haasnoot, M. (author), Van Deursen, W.P.A. (author), Guillaume, J.H.A. (author), Kwakkel, J.H. (author), Van Beek, E. (author), Middelkoop, H. (author)Exploring adaptation pathways is an emerging approach for supporting decision making under uncertain changing conditions. An adaptation pathway is a sequence of policy actions to reach specified objectives. To develop adaptation pathways, interactions between environment and policy response need to be analysed over time for an ensemble of...journal article 2014

De Wit, M.S. (author)This paper reports on an analysis of the uncertainty in wind pressure (difference) coefficients, which are assessed on the basis of generic knowledge and experimental data rather than with a specific (wind tunnel) experiment. The analysis is carried out on time averaged pressure coefficients in a specific case, concerning a low-rise building in...journal article 1999

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

Yao, W. (author), Chen, X. (author), Zhao, Y. (author), Van Tooren, M.J.L. (author)To comprehensively assess fractionated spacecraft, an assessment tool is developed based on lifecycle simulation under uncertainty driven by modular evolutionary stochastic models. First, fractionated spacecraft nomenclature and architecture are clarified, and assessment criteria are analyzed. The mean and standard deviation of risk adjusted...journal article 2012

Bouarfa, L. (author), Jonker, P.P. (author), Dankelman, J. (author)Recognizing and understanding surgical high-level tasks from sensor readings is important for surgical workflow analysis. Surgical high-level task recognition is also a challenging task in ubiquitous computing because of the inherent uncertainty of sensor data and the complexity of the operating room environment. In this paper, we present a...journal article 2010

Leijten, M. (author), Koppenjan, J.F.M. (author), Ten Heuvelhof, E.F. (author), Veeneman, W.W. (author), Van der Voort, H.G. (author)Due to the uncertainty involved in many complex infrastructure engineering projects, it is not always possible for managers to establish detailed terms of reference at the departure. Although the flexibility of ‘open’ terms of reference is often indispensible, it makes the arrival at a successful outcome much of a gamble. Complex infrastructure...journal article 2010

Taneja, P. (author), Ligteringen, H. (author), Walker, W.E. (author)Recently, flexibility has received much attention from port researchers, designers, and managers. This is because the stability of the competitive environment of the past has been replaced by increasing uncertainty. The current economic crisis and the recent trends in ports and shipping sectors are causing port planners to rethink their approach...journal article 2012

Wiebenga, J.H. (author), Van den Boorgaard, A.H. (author), Klaseboer, G. (author)The coupling of finite element simulations to mathematical optimization techniques has contributed significantly to product improvements and cost reductions in the metal forming industries. The next challenge is to bridge the gap between deterministic optimization techniques and the industrial need for robustness. This paper introduces a...journal article 2012

Rijcken, T. (author), Stijnen, J. (author), Slootjes, N. (author)The Dutch Delta Program is currently developing new government policies for flood protection and fresh water supply. Decision support instruments have to address the program’s technical and political complexity. The water system functions are highly interwoven and would benefit from an integrated approach on a national level, with decisions...journal article 2012

Pande, S. (author)A theory for quantile based hydrologic model selection and model structure deficiency assessment is presented. The paper demonstrates that the degree to which a model selection problem is constrained by the model structure (measured by the Lagrange multipliers of the constraints) quantifies structural deficiency. This leads to a formal...journal article 2013

Pande, S. (author)Quantile hydrologic model selection and structure deficiency assessment is applied in three case studies. The performance of quantile model selection problem is rigorously evaluated using a model structure on the French Broad river basin data set. The case study shows that quantile model selection encompasses model selection strategies based on...journal article 2013

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
