Infrastructure Risk Assessment & Management contains selected papers presented at both the 10th International Conference on Computer Simulation in Risk Analysis and Hazard Mitigation and the 14th International Conference on Structures under Shock and Impact, organized by the Wessex Institute. The papers cover a variety of topics, including impact and blast loading, response of buildings and other structures to blast and their dynamic behaviour. These are all areas of active research and general interest, focused on the survivability of physical facilities and the protection of people. It contains a series of research contributions, essential to deepen the knowledge of how structures and materials behave under a wide variety of dynamic load actions. Current events emphasise the importance of the analysis and management of risk to planners, civil authorities, law enforcement agencies, non-governmental organisations, information technology experts and many other researchers and practitioners throughout the world. This volume brings together the work of researchers and other professionals actively involved in finding new ways to cope with the increased demands for a more effective control of impact and blast effects as well as risk management and control.

The accelerated growth of the world population creates an increase of energy needs. This requires new paths for oil supply to its users, which can be potential hazardous sources for individuals and the environment. Risk Analysis for Prevention of Hazardous Situations in Petroleum and Natural Gas Engineering explains the potential hazards of petroleum engineering activities, emphasizing risk assessments in drilling, completion, and production, and the gathering, transportation, and storage of hydrocarbons. Designed to aid in decision-making processes for environmental protection, this book is a useful guide for engineers, technicians, and other professionals in the petroleum industry interested in risk analysis for preventing hazardous situations.

In this Thesis, we develop computational models for line failure risk and cascading power failures on bulk power systems. General reliability issues cost society billions of dollars and large blackouts from cascading power failures have an extreme impact on society and can lead to loss of life. We start by building an analytic formulation of the cascading simulation found in literature, formulating the problem as a multi-stage stochastic program with integer variables to model the decision-dependent uncertainty. This allows for the flexibility to include the cascading simulation in as a subproblem for optimization in long-term design problems. We then use the Monte Carlo simulation of the cascading process and large computational resources of HTCondor to optimize transmission capacity expansion to reduce the expected value of load shed for a set of initial contingencies. The second half of the thesis focuses on the five minute dispatch market for power systems. We develop a system risk measure that is a joint chance constraint on the probability that one or more lines fail, which we constrain to be a small number. We model the probability that one line fails as a piecewise linear function. Additionally, we model uncertainty in generation and demand as a multivariate Gaussian and form a linear approximation of our system risk measure under uncertainty. We solve this large, convex problem using cutting planes. In order to account for exogenous contingencies, we model the N-1 contingencies and apply our risk measure under uncertainty. Finally, we find weights to measure the impact of losing a particular transmission line using the cascading simulation to evaluate rare event stress. We use these weights in a new weighted version of a joint chance constraint with N-1 contingency and solve with cutting planes. These computational models explore rare event stress through the cascade simulation. They incorporate uncertainty in demand, the initial contingencies that start cascades, and the uncertainty in cascade evolution. The first two models look at long term design problems given a budget to improve infrastructure and the last two models look at the five minute market to reduce rare event risk.

This book presents several original theories for risk, including Theory of Risk Monitoring, and Theory of Risk Acceptance, in addition to several analytical models for computing relative and absolute risk. The book discusses risk limit, states of risk, and the emerging concept of risk monitoring. The interrelationships between risk and resilience are also highlighted in an objective manner. The book includes several practical case studies showing how risk management and its components can be used to enhance performance of infrastructures at reasonable costs.
