QR-decomposition method for solving fuzzy system of linear equations

S. H. Nasseri, M. Matinfar, M. Sohrabi


A convenient model of fuzzy linear systems is an n × n linear system whose coefficients matrix is crisp and the right-hand side column is an arbitrary fuzzy vector. In this paper, we consider an m×n fuzzy linear systems and propose the QR-decomposition method for solving fuzzy system of linear equations. The method in detail is discussed by convergence theorem. We illustrate our method by solving some numerical examples.
