Abstract:
Each validation process of the software system requirements should include an analysis of all possible scenarios, whereas only some of them are valid, some scenarios are redundant, and some scenarios cause unsafe behavior of the system. An important factor for successful checking of all possible scenarios is the possibility of automated searching and evaluation of scenarios. The crucial question is how to work with scenarios to get their evaluation at least partially automatically. In this area, there is a gap between what formal approaches can offer and how they are actually used. It comes from the belief that formal approaches are difficult for understanding and using, and that they are not suitable for validation because they have no executable form. Nevertheless, systematic formal description techniques allow to specify the system properties and the detailed form of the solution during the design process and to analyze system specification, including user interactions, and implement architectural design decisions. This work focuses on the use of Petri nets for specifying requirements and generating and analysis scenarios to validate this specification.
