Criteria		AHL – aggregation
Set 1: all of them	r 1	r* = r 1 ∧ r 2 ∧ … ∧ rn	Final result: R = r * ∧ s *
	r 2
	⫶
	r n
Set 2: at least one	s 1	s* = s 1 ∨ s 2 ∨ … ∨ s m
	s 2
	⫶
	s m
∧ = AND operation; ∨ = OR operation When r i and s i are uncertain probabilities or ranges, the aggregation is calculated for both lower and upper bounds.
