Nowadays, UML is considered to be the standardized language for object-oriented modeling and analysis. However, UML cannot be used for automatic analyses and simulation. In this paper, we propose an approach for transforming UML statechart and collaboration diagrams to Colored Petri net models. This transformation aims to bridge the gap between informal notation (UML diagrams) and more formal notation (Colored Petri net models) for analysis purposes. It produces highlystructured, graphical, and rigorously-analyzable models that facilitate early detection of errors such as deadlock and livelock. The approach is based on graph transformations where the input and output of the transformation process are graphs. The meta-modeling tool AToM3 is used. A case study is presented to illustrate our approach.

Model transformations have proved to be powerful in the development of critical systems. According to their intents, they have been used in many domains such as models refinement, simulation, and domain semantics. The formal methods have been successful in the verification and validation of critical systems, and in particular, in the formalization of UML, BPMN, and AADL. However, little research has been done on verifying the transformation itself. In this paper, we extend our previous work using Isabelle/HOL that transforms UML State Machine Diagrams (SMD) to Colored Petri nets (CPN) models and proves that certain structural properties of this transformation are correct. For example, the structural property: Bfor each final state of a SMD model a corresponding place in CPN model should be generated by the transformation^is described and checked using Isabelle/HOL as invariant property. In the current work, we use Scala as environment of executing Isabelle/HOL specifications and we perform the verified transformation using Scala. Moreover, we demonstrate our approach using another case study of transforming BPMN (Business Process Model and Notation) models into Petri nets models and verify the correctness of certain structural properties of this transformation.

The correctness of transformations has recently begun to attract the attention of the researchers in Model Driven Engineering (MDE). The objective of this article is twofold. First, it presents an approach for transforming BPMN models to Colored Petri nets models using GROOVE and EMF/Xpand tools. Second, it proposes an approach for checking the correctness of the transformation itself. More precisely, we have defined the termination property of the transformation and the preservation of some structural properties of BPMN models by the transformation using the GROOVE graph transformation tool. The authors have also applied the approach on a case study through which the authors have verified the successful termination of the transformation using GROOVE Model Checker and the target model properties using CPN Tools.

Mobile agent-based applications are special type of software systems which take the advantages of mobile agents in order to provide a new beneficial paradigm to solve multiple complex problems in several fields and areas such as network management, e-commerce, e-learning, etc. Likewise, we notice lack of real applications based on this paradigm and lack of serious evaluations of their modeling approaches. Hence, this paper provides a comparative study of modeling approaches of mobile agent-based software systems. The objective is to give the reader an overview and a thorough understanding of the work that has been done and where the gaps in the research are.

The most important advantage of Model Driven Engineering (MDE) is making available tools, concepts and languages to create and transform models. In this paper, we propose a framework to transform automatically UML activity diagram 2.0 (informal notation) to Petri Nets (formal notation) for the analysis purpose using INA analyzer tool. This transformation helps the software designers to analyze and verify properties. For realizing this transformation, we have proposed a meta-model for UML-AD and another one for PN. Based on these meta-models, we define a graph grammar that performs the transformation process. AToM3 is used as a tool for meta-modeling and graph transformation. We verify the resulting Petri nets with model checker INA. We illustrate our contribution with a detailed example.
