The concept of outer regular fuzzy measures is proposed, and it is sho
wn that a functional of certain type on the cone of positive continuou
s functions with compact supports is represented as a Choquet integral
with respect to a outer regular fuzzy measure. It is also shown that
the Choquet integral of positive continuous functions with compact sup
ports is represented as a Lebesgue integral with the same integrands.
This representation is a generalization of certain previous results of
others, which are useful for computation of the upper and lower expec
ted value. (C) 1998 Elsevier Science B.V. All rights reserved.
