TrapezoidalFuzzyNumber-class: S4 class Representing a Trapezoidal Fuzzy Number

In FuzzyNumbers: Tools to Deal with Fuzzy Numbers

Description

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

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.
