In this paper, we study the solution of n X n fuzzy linear system Ax = b where A is a singular crisp matrix, x and b are vectors of fuzzy numbers. We first convert the fuzzy linear system Ax = b to 2n X 2n crisp linear system SX = Y. where S is a singular matrix. We then apply the Drazin inverse to solve the 2n X 2n crisp linear system SX = Y. To investigate the effect of Drazin inverse, we apply the QR decomposition method. Several numerical examples are discussed. [ABSTRACT FROM AUTHOR] |
