Predicting the response of complex systems for coastal management

Hendrickx, G.G. (author), Antolínez, José A. Á. (author), Herman, P.M.J. (author)

In recent years, coastal management has been facing new challenges: socio-economic growth and consequent climate change impose new boundary conditions pushing coastal systems towards unseen states. For adaptation and mitigation strategies as well as risk management, the resilience of systems to these projected changes must be tested and...

Risk consequence assessment of dam breach in cascade reservoirs considering risk transmission and superposition

Wang, Te (author), Li, Zongkun (author), Ge, W. (author), zhang, Z.H. (author), Zhang, Yadong (author), Sun, Heqiang (author), Jiao, Yutie (author)

Compared with a single reservoir, the risk in cascade reservoirs has the transmission and superposition effect, which increases the complexity of its risk consequence assessment. In view of this problem, the direct consequence (DC) and potential consequence (PC) were defined as two parts of the dam breach risk consequence of cascade reservoirs....

Prediction-Based Reachability Analysis for Collision Risk Assessment on Highways

Wang, X. (author), Li, Z. (author), Alonso-Mora, J. (author), Wang, M. (author)

Real-time safety systems are crucial components of intelligent vehicles. This paper introduces a prediction-based collision risk assessment approach on highways. Given a point mass vehicle dynamics system, a stochastic forward reachable set considering two-dimensional motion with vehicle state probability distributions is firstly established. We...

A cyber-risk framework for coordination of the prevention and preservation of behaviours

Parkin, S.E. (author), Chua, Yi Ting (author)

Cybersecurity controls are deployed to manage risks posed by malicious behaviours or systems. What is not often considered or articulated is how cybersecurity controls may impact legitimate users (often those whose use of a managed system needs to be protected, and preserved). This oversight characterises the blunt' nature of many cybersecurity...

Resilience Assessment at the State Level Using the Sendai Framework

De Iuliis, Melissaw (author), Kammouh, O. (author), Cimellaro, Gian Paolo (author)

The multitude of uncertainties of both natural and man-made disasters have prompted an increased attention in resilience engineering and disaster management. To overcome the effects of disastrous events, such as economic and social effects, modern communities need to be resilient. Natural disasters are unpredictable and unavoidable. While it is...

Risk, Uncertainty, and Ignorance in Engineering Systems Design

Oehmen, Josef (author), Kwakkel, J.H. (author)

Uncertainty is the third major perspective in understanding and designing engineering systems, along with complexity and human behaviour. Risk, a corollary of uncertainty, is understood as the effect of uncertainty on objectives. When designing engineering systems, you cannot not manage risk - even ignoring risk equates to a decision to accept...

Biases in security risk management: Do security professionals follow prospect theory in their decisions?

de Wit, J.J. (author), Pieters, Wolter (author), Jansen, S.J.T. (author), van Gelder, P.H.A.J.M. (author)

Security professionals play a decisive role in security risk decision making, with important implications for security in organisations and society. Because of this subjective input in security understanding possible biases in this process is paramount. In this paper, well known biases as observed and described in prospect theory are studied in...

Individual preferences in security risk decision making: an exploratory study under security professionals

de Wit, J.J. (author), Pieters, W. (author), van Gelder, P.H.A.J.M. (author)

Risk assessments in the (cyber) security domain are often, if not always, based on subjective expert judgement. For the first time, to the best of our knowledge, the individual preferences of professionals from the security domain are studied. In on online survey they are asked to mention, rate and rank their preferences when assessing a...

Responsible Learning About Risks Arising from Emerging Biotechnologies

Bouchaut, B.F.H.J. (author), Asveld, L. (author)

Genetic engineering techniques (e.g., CRISPR-Cas) have led to an increase in biotechnological developments, possibly leading to uncertain risks. The European Union aims to anticipate these by embedding the Precautionary Principle in its regulation for risk management. This principle revolves around taking preventive action in the face of...

The development of safety validation methods is essential for the safe deployment and operation of Automated Driving Systems (ADSs). One of the goals of safety validation is to prospectively evaluate the risk of an ADS dealing with real-world traffic. ISO 26262 and ISO/DIS 21448, the leading standards in automotive safety, provide an approach...

Cost contingency and cost evolvement of construction projects in the preconstruction phase

Hoseini, E. (author), Bosch-Rekveldt, M.G.C. (author), Hertogh, M.J.C.M. (author)

The current literature discusses the methods to estimate the costs and cost contingency. The literature also distinguishes "known unknowns" and "unknown unknowns" contingencies. Little is written, however, about the evolvement of total project cost estimates during the preconstruction phase of construction projects. Moreover, not many studies...
