Description
Risk Analysis, Second Edition
Terje Aven, University of Stavanger, Norway
A practical guide to the varied challenges presented in the ever-growing field of risk analysis.
Risk Analysis presents an accessible and concise guide to performing risk analysis, in a wide variety of field, with minimal prior knowledge required. Forming an ideal companion volume to Aven's previous Wiley text Foundations of Risk Analysis, it provides clear recommendations and guidance in the planning, execution anduse of risk analysis.
This new edition presents recent developments related to risk conceptualization, focusing on related issues on risk assessment and their application. New examples are also featured to clarify the reader's understanding in the application of risk analysis and the risk analysis process.
Key features:
* Fully updated to include recent developments related to risk conceptualization
and related issues on risk assessments and their applications.
* Emphasizes the decision making context of risk analysis rather than
just computing probabilities
* Demonstrates how to carry out predictive risk analysis using a variety of case studies and examples.
* Written by an experienced expert in the field, in a style suitable for both
industrial and academic audiences.
This book is ideal for advanced undergraduates, graduates, analysts and researchers from statistics, engineering, finance, medicine and physical sciences. Managers facing decision making problems involving risk and uncertainty will also benefit from this book.
