Risk analysis under attack: How risk science can address the legal, social, and reputational liabilities faced by risk analysts.

The role of the risk analyst is critical in understanding and managing uncertainty. However, there is another type of uncertainty that is rarely discussed: The legal, social, and reputational liabilities of the risk analyst. Recent events have shown that professionals participating in risk analysis can be held personally liable.

Managing Physical and Economic Risk for Systems with Multidirectional Network Interdependencies.

Critical infrastructure networks, such as transportation and supply chains, are becoming increasingly interdependent. As the operability of network nodes relies on the operability of connected nodes, network disruptions have the potential to spread across entire networks, having catastrophic consequences in the realms of physical network performance and also economic performance. While risk-informed physical network models and economic models have been well-studied in the literature, there is limited study of how physical features of network performance interact with sector-specific economic performance, particularly as these physical networks recover from disruptions of varying durations.

Risk Science in Higher Education: The Current and Future Role of Risk Science in the University Curriculum.

Risk and uncertainty are critical elements for decision making across fields, such as business, policy, engineering, and healthcare. As universities maintain and adapt curriculums to ensure their graduates are prepared for risk-related roles, there is momentum for risk science to be included in the curriculum. The study of risk science can be observed in programs devoted to risk fundamentals (for example on basic concepts like risk and probability) and risk assessment, risk perception and communication, and risk management and governance.

A Risk-Science Approach to Vulnerability Classification.

Advancements in the risk literature and recent events have highlighted the need for recognizing and managing system vulnerabilities. However, established definitions of vulnerability typically involve only static concepts that are limited to measurement of system characteristics. Advancements in risk modeling, combined with the dynamic nature of data availability, and processing call for the need to understand the various dimensions and time-dependent properties of vulnerability within risk-informed decision making.

Decision-Making Analytics Using Plural Resilience Parameters for Adaptive Management of Complex Systems.

It is critical for complex systems to effectively recover, adapt, and reorganize after system disruptions. Common approaches for evaluating system resilience typically study single measures of performance at one time, such as with a single resilience curve. However, multiple measures of performance are needed for complex systems that involve many components, functions, and noncommensurate valuations of performance.

Supply Chain Vulnerability Analysis Using Scenario-Based Input-Output Modeling: Application to Port Operations.

Disruptive events such as natural disasters, loss or reduction of resources, work stoppages, and emergent conditions have potential to propagate economic losses across trade networks. In particular, disruptions to the operation of container port activity can be detrimental for international trade and commerce. Risk assessment should anticipate the impact of port operation disruptions with consideration of how priorities change due to uncertain scenarios and guide investments that are effective and feasible for implementation.

Understanding and managing disaster evacuation on a transportation network.

Uncertain population behaviors in a regional emergency could potentially harm the performance of the region's transportation system and subsequent evacuation effort. The integration of behavioral survey data with travel demand modeling enables an assessment of transportation system performance and the identification of operational and public health countermeasures. This paper analyzes transportation system demand and system performance for emergency management in three disaster scenarios.

Decision analysis and risk models for land development affecting infrastructure systems.

Coordination and layering of models to identify risks in complex systems such as large-scale infrastructure of energy, water, and transportation is of current interest across application domains. Such infrastructures are increasingly vulnerable to adjacent commercial and residential land development. Land development can compromise the performance of essential infrastructure systems and increase the costs of maintaining or increasing performance.
