In this paper, we propose two numerical methods, namely: Gauss– Jacobi and
Gauss–Seidel iterative schemes to solve the Positive Triangular Fully Fuzzy Linear System.
A description of these numerical schemes and their convergence properties have been
presented. Numerical example with known exact solution are given to illustrate the
efficiency of the proposed methods. Numerical results show clearly that the Gauss–Seidel
method provides more efficient results than its counterparts.
