Solving systems of linear fuzzy equations. (English) Zbl 0741.65023
Methods for solving a set of fuzzy linear equations are given. The author presents six new solutions and shows that five of these are identical and can be combined. It is shown how these new results are related to the previous research in the area. It is pointed out that the classical solution technique, based on an extension principle and regular fuzzy arithmetic, should be rejected since too often it fails.
