We study the use of formal modeling and verification techniques at an early stage in the development of safety-critical automotive products which are originally described in the domain specific architectural language EAST-ADL2. This architectural language only focuses on the structural definition of functional blocks. However, the behavior inside each functional block is not specified and that ...

Integrating Object Oriented (OO) modeling language and Petri Net (PN) modeling is important to gather complementary benefits of these two modeling languages. OO technology is used to describe the static aspects of systems because of its powerful structuring capabilities, whereas PN is used to model the behavioral aspects for concurrent and non deterministic applications. PN is an executable mod...

We present an approach to systematic, toolsupported design and development of JAVA CARD applets. We employ the Unified Modeling Language (UML) and formal methods for object-oriented software development in our approach. Our goal is to make JAVA CARD applets robust “by design”, to make the development process independent of the JAVA CARD platform, and to enable applets to be verified formally by...

This paper proposes a visual modeling language for a large-scale hybrid system based on discrete event system specification formalism. Within theproposed language, basic model diagrams define the hybrid behavior of systems, whilethe structure can be represented through coupled model diagrams. The language can visually define large-scale hybrid systems without a sacrifice of formal semantics, an...

The necessity of a methodology for developing multi-agent systems (MAS) has been widely recognized due to the difficulties in analysis, specification, design, implementation and testing the autonomous and collaborative behaviours of such systems. This paper presents CAMLE – a caste-centric agent modeling language and environment. The methodology underlying the language and environment is based ...

Unified Modeling Language (UML) is currently accepted as the standard for modeling (objectoriented) software, and its use is increasing in the aerospace industry. Verification and Validation of complex software developed according to UML is not trivial due to complexity of the software itself, and the several different UML models/diagrams that can be used to model behavior and structure of the ...

In this paper we present a framework for software process verification called Alloy4SPV which uses a subset of UML2 Activity Diagrams as a process modeling language. In order to achieve software process verification, we i) define a formal model of our process modeling language using first-order logic, ii) we give it a formal semantics based on the fUML standard, and iii) we implement this forma...

With the increasing complexity of real-world energy systems its modeling process becomes even more crucial when large-scale simulations are conducted. Being computational intensive and therefore requiring efficient simulation models a modeling scheme with a well-defined formal syntax definition is developed and together with its meta model proposed in this paper. This Universal Scheme for model...

We report on our experiences with formal specification and verification of variable and customizable software realized in a software product family architecture using the Java Modeling Language (JML) and the KeY verification system. Software product families can be adapted to different deployment scenarios and provide instantiable feature sets as requested by the customer. Along a small case st...
