Теория принятия решений — это изучение того, как agents делают choices under uncertainty, values, objectives и beliefs. Она включает normative approaches, предписывающие rational decision-making, и descriptive approaches, анализирующие, как decisions actually made.
(Also theory of choice.) The study of the reasoning underlying an agent's choices. Decision theory can be broken into two branches: normative decision theory, which gives advice on how to make the best decisions given a set of uncertain beliefs and a set of values, and descriptive decision theory which analyzes how existing, possibly irrational agents actually make decisions.
