This paper proposes new matrix methods for solving positive solutions for a positive Fully
Fuzzy Linear System (FFLS). All coefficients on the right hand side are collected in one block
matrix, while the entries on the left hand side are collected in one vector. Therefore, the
solution can be gained with a non-fuzzy common step. The necessary theorems are derived
to obtain a necessary and sufficient condition in order to obtain the solution. The solution for
FFLS is obtained where the entries of coefficients are unknown. The methods and results …
