A new method for solving real and complex fuzzy systems of linear equations

A new approach to solving fuzzy real and complex systems of linear equations based on the fuzzy center and width is presented here. The unknown variable and right-hand side vector are considered as fuzzy, whereas the coefficient matrix is considered as crisp. First the system is solved in terms of the fuzzy center, and then this solution is used with the width to get the final solution of the original system. The presented procedure is applied to analyze three example problems. The results obtained are also compared with the known solutions and are found to be in good agreement.
