Event‐Tree Analysis with Imprecise Probabilities

Risk Analysis, 2011
Novel methods are proposed for dealing with event‐tree analysis under imprecise probabilities, where one could measure chance or uncertainty without sharp numerical probabilities and express available evidence as upper and lower previsions (or expectations) of gambles (or bounded real functions). Sets of upper and lower previsions generate a convex set

Introduction to Imprecise Probabilities

2020
Since uncertainty is persistent in engineering analyses, this chapter aimed to introduce methods to describe and reason with under uncertainty in various scenarios. Probability theory is the most widely used methodology for uncertainty quantification for a long time and has proven to be a powerful tool for this task.

Constructing imprecise probability distributions

International Journal of General Systems, 2005
In this current paper the following problems are addressed: (1) extending the knowledge of a partially known probability distribution function to any point of a continuous sample space, (2) constructing an imprecise probability distribution based on the knowledge of a set of credible or confidence intervals, and (3) computing the lower and upper ...

Imprecise probabilities and scenarios

Futures, 2005
Abstract This paper argues that imprecise probability can be used to describe uncertainty about scenarios. Scenarios are conceptualized as written descriptions of potential future worlds that are based on assessments of economic, political, social, technological, and environmental trends [This description of scenarios follows that provided by Peter ...

Discounting Imprecise Probabilities

2018
In this paper it is considered the problem of discounting a credal set of probability distributions by a factor \(\alpha \) representing a degree of unreliability of the information source providing the imprecise probabilistic information. An axiomatic approach is followed by giving a set of properties that this operator should satisfy.
