Abstract: Because of the natural essence of requirements, uncertainty in information systems is unavoidable. To develop the systems (analyze, design, implementation, test) object oriented methods describes their concepts, with UML language. UML as a standard object oriented language has ability to investigate the different aspects of behavioral and structural in software engineering. If enter the uncertainty in UML, the extended version named Fuzzy-UML will be produced. This developed version includes both of structure and behavior sights. Because of the lack of UML ability support for evaluation, the necessity of transforming the pragmatic model of (UML) system to the formal model (Petri Nets) is considered (because of being uncertain of the information, the pragmatic model transforms to the Fuzzy Petri Net formal model). We will have the ability of evaluating the complex systems, with preparing the proper model of system.
