The width (Chanas, 2001) is a measure of nonspecificity of a fuzzy number.
# S4 method for FuzzyNumber
width(object, ...)a fuzzy number
additional arguments passed to expectedInterval
Returns a single numeric value.
The width of \(A\) is defined as
\(width(A) := EI_U(A) - EI_L(A)\),
where \(EI\) is the expectedInterval.
