WebJan 30, 2024 · The occurrence of only one uncertainty (aleatory or epistemic) can also be referred to as monomorphic uncertainty, whereas the joint occurrence is called polymorphic uncertainty. The uncertainty quantification could be carried out based on, e.g., a probabilistic approach, a possibilistic approach, or even a combination of both techniques.
