In this work, we propose an approach for computing the compromised solution of an LR
fuzzy linear system by using of a ranking function when the coefficient matrix is a crisp mn
matrix. To do this, we use expected interval to find an LR fuzzy vector, X , such that the vector
(AX ) has the least distance from (b) in 1 norm and the 1 cut of X satisfies the crisp linear
system AX = b ...
