Description

The width (Chanas, 2001) is a measure of nonspecificity of a fuzzy number.

Usage

## S4 method for signature 'FuzzyNumber'
width(object, ...)

Arguments

object

a fuzzy number

...

additional arguments passed to expectedInterval

Details

The width of A is defined as width(A) := EI_U(A) - EI_L(A), where EI is the expectedInterval.

Value

Returns a single numeric value.
