Invers dan General Invers untuk Matriks Bilangan Fuzzy Heksagonal
This thesis discusses regarding inverse and general inverse for hexagonal fuzzy
numbers matrix. In this matter, by changing hexagonal fuzzy numbers ea =
(a, b, α1, α2, β1, β2) into parametric form ea(r) = [b2(r), b1(r), b1(r), b2(r)] it defines
two center points, which are m1(ea) and m2(ea) for any hexagonal fuzzy ea. Such
that the arithmetic forms of multiplication, division and inverse exist with a
single a−1 = 1/ea which yields ea(r) ⊗ ea(r)−1 = i(r). Then, the constructed
arithmetic is used to determine inverse matrix of hexagonal fuzzy numbers by
using elementary row operation method that produces e A(r) ⊗ e A(r)−1 = eI(r).
General inverse method is used to determine inverse matrix of hexagonal fuzzy
numbers for singular matrix and non-square matrix.
Keywords: Fuzzy number arithmetic, hexagonal fuzzy number, inverse dan
generalisized inverse.
