Alternatif Aritmatika Bilangan Fuzzy Pentagonal
This thesis discusses the arithmetic alternatives to pentagonal fuzzy
numbers. The
discussion begins
with
the definition of
the positivity
of
pentagonal
fuzzy numbers which
is
constructed using a
ratio of areas
in
the positive r-axis and negative r-axes (in the first quadrant and the second
quadrant). Then, from the concept of positivity fuzzy numbers, an alternative arithmetic for pentagonal fuzzy numbers is constructed. Then the multiplica-tion form of pentagonal fuzzy numbers can be obtained in some cases. Finally, from the multiplication operations, it is applied to determine the multiplication identity and inverse of pentagonal fuzzy numbers.
Keywords: Arithmetic fuzzy number, pentagonal fuzzy number, positivity of fuzzy number
