FuzzyNumbers (version 0.4-6)

TrapezoidalFuzzyNumber-class: S4 class Representing a Trapezoidal Fuzzy Number

Description

Trapezoidal Fuzzy Numbers have linear side functions and alpha-cut bounds.

Slots

a1, a2, a3, a4, lower, upper, left, right:

Inherited from the '>FuzzyNumber class.

Extends

Class '>FuzzyNumber, directly.

Details

Trapezoidal fuzzy numbers are among the simplest FNs. Despite their simplicity, however, they include triangular FNs, ``crisp'' real intervals, and ``crisp'' reals. Please note that currently no separate classes for these particular TFNs types are implemented in the package.
