A Novel Method for Modeling and Evaluation of Uncertain Information Systems

None of the processing models in the software development has explained the software systems performance evaluation and modeling; likewise, thereexist uncertainty in the information systems because of the natural essence of requirements and this may cause other challenges in the processing of software development. By the definition of UML extended version (Fuzzy UML), software functionality requirements that are stated in anuncertain way are supported; moreover, the concrete model is converted to formal model for modeling and performance evaluation of the software systems. Thispaper describes a methodology to develop a fuzzy coloured Petri net (F-CPN) model of a system. The FCPN model can be analyzed by formal Petri net analysis techniques.
