A New Method for Solving General Dual Fuzzy Linear Systems

Mahmood Otadi


According to fuzzy arithmetic, general dual fuzzy linearsystem (GDFLS) cannot be replaced by a fuzzy linear system (FLS). Inthis paper, we use new notation of fuzzy numbers and convert a GDFLSto two linear systems in crisp case, then we discuss complexity of theproposed method. Conditions for the existence of a unique fuzzy solutionto n × n GDFLS are derived.
