The author provides the readers with the knowledge and basic thinking they require to successfully manage risk and uncertainty to support decision making.This updated edition reflects recent developments on risk and uncertainty concepts, representations and treatment.New material inFoundations of Risk Analysisincludes:An up to date presentation of how to understand, define and describe risk based on research carried out in recent years.A new definition of the concept of vulnerability consistent with the understanding of risk.Reflections on the need for seeing beyond probabilities to measure/describe uncertainties.A presentation and discussion of a method for assessing the importance of assumptions (uncertainty factors) in the background knowledge that the subjective probabilities are based onA brief introduction to approaches that produce interval (imprecise) probabilities instead of exact probabilities.In addition the new version provides a number of other improvements, for example, concerning the use of cost-benefit analyses and the As Low As Reasonably Practicable (ALARP) principle.Foundations of Risk Analysisprovides a framework for understanding, conducting and using risk analysis suitable for advanced undergraduates, graduates, analysts and researchers from statistics, engineering, finance, medicine and the physical sciences, as well as for managers facing decision making problems involving risk and uncertainty.目录Preface to the second edition ixPreface to the first edition xi1 Introduction 11.1 The importance of risk and uncertainty assessments 11.2 The need to develop a proper risk analysis framework 4Bibliographic notes 62 Common thinking about risk and risk analysis 72.1 Accident risk 72.1.1 Accident statistics 72.1.2 Risk analysis 112.1.3 Reliability analysis 242.2 Economic risk 282.2.1 General definitions of economic risk in business and project management 282.2.2 A cost risk analysis 302.2.3 Finance and portfolio theory 312.2.4 Treatment of risk in project discounted cash flow analysis 342.3 Discussion and conclusions 362.3.1 The classical approach 362.3.2 The Bayesian paradigm 372.3.3 Economic risk and rational decision-making 392.3.4 Other perspectives and applications 402.3.5 Conclusions 43Bibliographic notes 433 How to think about risk and risk analysis 473.1 Basic ideas and principles 473.1.1 Background knowledge 523.1.2 Models and simplifications in probability considerations 533.1.3 Observable quantities 533.2 Economic risk 543.2.1 A simple cost risk example 543.2.2 Production risk 573.2.3 Business and project management 593.2.4 Investing money in a stock market 603.2.5 Discounted cash flow analysis 613.3 Accident risk 623.4 Discussion 63Bibliographic notes 684 How to assess uncertainties and specify probabilities 714.1 What is a good probability assignment?
