Alternatif Aljabar Untuk Bilangan Fuzzy Pentagonal

Abstract

A part of the triangular fuzzy numbers, is what we call pentagonal fuzzy numbers. Plenty
of alternatives for fuzzy pentagonal numbers are suggested by some writers. Particularly
for scalar summation, subtraction, and multiplication, there is no enormous diversity.
However, for multiplication, division, and inverse as well, there are so many algebraic
options proposed by various scholars. Some writers defined the form of inverse for
pentagonal fuzzy numbers in parametric. But it does not always result in identity. Such
a thing will also have implications in the process of how to invers the pentagonal fuzzy
numbers matric. This paper proposes an alternative method to decide the inverse of
pentagonal fuzzy numbers, in the form of parametric. The first thing to do is to
construct two midpoint for any pentagonal fuzzy. The midpoint are used to construct
the multiplication, division and inverse. Algebraic to any pentagonal fuzzy number in
any single inverse such that it produces an identity inverse, likewise for a pentagonal
fuzzy number matrix it produces an identity matrix inverse.
