Abstract:
This article discusses the diagonalization of a matrix triangular fuzzy numbers in
interval form. Negative positive triangular fuzzy number based on geometrical area
can be used to determine eigenvalues and eigenvector of matrix triangular fuzzy
numbers in interval form matrix using arithmatic operation that have been modi ed
which refers to eigenvalues and eigenvectors of real matrix. Then, to determine the
matrix triangular fuzzy numbers in interval form can be diagonalised or not, used
eigenvalues and eigenvector of matrix triangular fuzzy numbers in interval form.
