The paper describes results of a European benchmark exercise in risk analysis of an ammonia storage facility. The comparison of results from the participants in the exercise showed significant differences, both in the frequency-and in the consequence assessment. The causes of some of these differences are discussed in the second part of the paper. This(More)
The theory of imprecise previsions admits the use of a wide variety of statistical evidence. Nevertheless, some existing evidence, for example, in reliability applications, cannot be utilized by models developed within its framework. In the pursuit of reducing imprecision, any available evidence should become an input to modeling. It is suggested to take a(More)
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 expected(More)
