A Formal Semantics of UML StateCharts by Means of Timed Petri Nets
نویسنده
چکیده
This paper deals with the formalization of Unified Modeling language (UML) by means of Petri Nets. In order to improve the semantics of UML dynamic diagrams, we define a new method of embedding UML StateCharts into Interval Timed Petri Nets (ITPN). This method considers all kinds of hierarchical states together with the most of pseudo-states like history ones. Besides consistencies analysis, time intervals of ITPN model well event generation and dispatching delays making it possible to achieve performance and time properties analysis of complex systems.

A Framework for the Verification of UML Models. Examples Using Petri Nets
This paper presents a framework for the verification of UML models. Our approach is to build meta-models for the different UML diagrams and translate them into formalisms (whose syntax is also specified with a meta-model) in which properties of interest can be proved. The translation (denotational semantics) as well as the formalisms operational semantics are formally described by means of grap...
متن کاملTransforming Fuzzy State Diagram to Fuzzy Petri net
UML is known as one of the most common methods in software engineering. Since this language is semi-formal, many researches and efforts have been performed to transform this language into formal methods including Petri nets. Thus, the operation of verification and validation of the qualitative and nonfunctional parameters could be achieved with more ability. Since the majority of the real world...

متن کاملRoles at the basis of UML validation
Formal validation of UML models proves to be hardly realizable, due to the imprecise semantics of UML dynamic diagrams. To remedy that, we first present a technique for transforming UML statecharts into Petri nets. We develop afterwards, an approach based on the movement of the objects throughout the roles they play. This approach allows validation of the temporal logic properties translated fr...
متن کاملImproving UML with Petri nets
UML is the OMG standard notation for object-oriented modeling. It is easy, graphical and appealing, but in several cases still too imprecise. UML is strong as modeling means, supplies several different diagrammatic notations for representing the different aspects of a system under development, but lacks simulation and verifiability capabilities. This drawback comes from its semi-formal nature: ...
