acuttrfn: Alpha-cut of trapezoidal fuzzy number

Description

This function for calculating alpha-cut of trapezoidal fuzzy number. See detail in references.

Usage

acuttrfn(left, lmid, rmid, right, acut.level = seq(0, 1, by = 0.1))

Value

AL is alpha-cut level,

XL.AL is a lower alpha-cut point of trapezoidal fuzzy number, and XU.AL is a upper alpha-cut point of trapezoidal fuzzy number.

Arguments

left

the left point of trapezoidal fuzzy number

lmid

the left-middle point of trapezoidal fuzzy number

rmid

the right-middle point of trapezoidal fuzzy number

right

the right point of trapezoidal fuzzy number

acut.level

the alpha-cut level of trapezoidal fuzzy number
