All firms, as entities having the same organizing patterns can be noticed to perform their current activity as components within a certain ensemble, which economists are used to calling environment. It is within the operation of this ensemble that the element of risk does appear. The latter...

In a quantitative model with uncertain inputs, the uncertainty of the output can be summarized by a risk measure. We propose a sensitivity analysis method based on derivatives of the output risk measure, in the direction of model inputs. This produces a global sensitivity measure, explicitly...

We consider the problem where a modeller conducts sensitivity analysis of a model consisting of random input factors, a corresponding random output of interest, and a baseline probability measure. The modeller seeks to understand how the model (the distribution of the input factors as well as...

Humans play important roles in the process of quantifying uncertainty. The participation of humans in this important exercise opens the process to behavioral biases. In this paper, we examine the different types of biases that may occur when quantifying uncertainty using a process-oriented...

This paper proposes a new method to introduce coherent risk measures for risks with infinite expectation, such as those characterized by some Pareto distributions. Extensions of the conditional value at risk, the weighted conditional value at risk and other examples are given. Actuarial...
