GSGD {FuzzySTs}

Calculates a distance between fuzzy numbers

Description

Calculates a distance between fuzzy numbers

Usage

GSGD(X, Y, i = 1, j = 1, thetas = 1, breakpoints = 100)

Arguments

X

a fuzzy number.

Y

a fuzzy number.

i

parameter of the density function of the Beta distribution, fixed by default to i = 1.

j

parameter of the density function of the Beta distribution, fixed by default to j = 1.

thetas

a decimal value between 0 and 1, representing the weight given to the shape of the fuzzy number. By default, thetas is fixed to 1. This parameter is used in the calculations of the d_theta star and the d_GSGD distances.

breakpoints

a positive arbitrary integer representing the number of breaks chosen to build the numerical alpha-cuts. It is fixed to 100 by default.

Value

A numerical value.
