The ambiguity (Delgado et al, 1998) is a measure of nonspecificity of a fuzzy number.
# S4 method for FuzzyNumber
ambiguity(object, ...)a fuzzy number
additional arguments passed to alphaInterval
Returns a single numeric value.
The ambiguity is defined as \(amb(A) := \int_0^1 \alpha\left(A_U(\alpha)-A_L(\alpha)\right)\,d\alpha\).
