This paper describes the modeling language as an extension for architectural reconfiguration to the existing distributed hybrid system modeling language Charon. The target application domain of R-Charon includes but is not limited to modular reconfigurable robots and large-scale transportation systems. While largely leaving the Charon syntax and semantics intact, R-Charon allows dynamic creatio...

For a given specific problem an efficient algorithm has been the matter of study. However, an alternative approach orthogonal to this approach comes out, which is called a reduction. In general for a given specific problem this reduction approach studies how to convert an original problem into subproblems. This paper proposes a formal modeling language to support this reduction approach in orde...

This paper provides an overview of a formal approach to serviceoriented modelling that we have been developing within the SENSORIA project [47]. A modelling language – SRML – and a number of formal techniques that address qualitative and quantitative analysis support this approach, all of which are based on mathematical foundations. Our focus will be on the language primitives that SRML offers ...

The Unified Modeling Language (UML) is a widely used general purpose modeling language. Together with the Object Constraint Language (OCL), formal models can be described by defining the structure and behavior with UML and additional OCL constraints. In the development process for formal models, it is important to make sure that these models are (a) correct, i.e. consistent and complete, and (b...

Recently, the main trends in software engineering have been dominated by the Model Driven Architecture (MDA) [1] vision of the Object Management Group (OMG). According to MDA, software development will be driven by a thorough modeling phase where (i) first a platform independent model (PIM) of the business logic is constructed from which (ii) platform specific models (PSMs) including details of...

In this article we argue in favour of Natural Deduction Systems as a basis for formal proof explanations. We illustrate our choice presenting a Natural Deduction for ALCQI and use it to help explain UML reasoning.

The EDEMOI project aims to model standards that regulate airport security. It involves the production of a UML model, to support the validation activity, and a formal model for verification purposes. This paper discusses the use of the RoZ tool to establish a strong link between both models and lists the problems faced during this translation.

Formal modeling of computing systems yields models that are intended to be correct with respect to the requirements that have been formalized. The complexity of typical computing systems can be addressed by formal refinement introducing all the necessary details piecemeal. We report on preliminary results that we have obtained for tracing informal natural-language requirements into formal model...

This paper presents an approach for transforming UML class diagrams and extended sequence diagrams into Colored Petri Nets. In the field of software model, UML has become a widely used software modeling language. However, as a semi-formal language, UML lacks a precise formal semantic base for its notation. In this paper, Colored Petri Nets are taken as the formal language for UML models' analys...
