Review of Uncertainty Oriented Mathematical Methods

Until the late sixties probability theory and statistics were the only methods to quantify uncertainties. Since that time new mathematical theories have been developed to handle uncertainties and to model them. We call them uncertainty oriented methods wh

Foreword

Risk analysis is an area of research that becomes more and more important, especially concerning environmental problems, due to the increasing industrial and human activities. The problem addressed by risk analysis is to predict whether or not, based on observations and current expert knowledge, some undesirable physical phenomenon is likely to occur or not. Very often, it aims to make sure that though appropriate decisions, a given physical system (or ecosystem) will not be affected by undesirable phenomena (like pollution, for instance). In order to face this kind of problem, a crucial issue is to represent the existing uncertainty pervading the physical system understudy. Indeed, measurements one can perform are often sparse, and human knowledge must be taken in account. So it is hard to address risk
