Aleatoorset

Aleatoorset is a theoretical construct used in uncertainty representation that combines elements of aleatoric randomness with set-based modeling. The term suggests a structured collection of potential outcomes tied to different states of the world, enabling the explicit representation of both intrinsic randomness and incomplete information within a single framework.

Formal idea: An aleatoorset can be thought of as a family of outcome sets, one for each scenario, together with a weighting or probability assignment that reflects how likely each scenario is. Within a given scenario, the outcomes form a set that may carry bounds or imprecise probabilities rather than a single precise value.

Relation to existing concepts: The approach shares aims with imprecise probability, random set theory, and Dempster-Shafer theory, providing a way to model ambiguity about both the presence and the likelihood of outcomes. It generalizes traditional probabilistic models by allowing interval or belief-based measures in addition to point probabilities.

Applications and use: In risk analysis, engineering design, and decision making under uncertainty, aleatoorset concepts can guide robust strategies by evaluating performance across multiple plausible outcomes and scenarios rather than relying on a single forecast.

Limitations and status: The term is not widely standardized and remains a niche concept in theoretical discussions. Notational conventions, interpretive choices, and computational methods vary, which can limit cross-study comparability.
