In this paper we will present our approach which fulfills all these requirements considering an example taken from the RailCab research project. The rules can at first be employed to define reconfiguration steps for the system which reduce the provided level of fault tolerance while retaining the provision of functional properties. Fault tolerance patterns are easily applied during the design of component-based systems to increase the reliability or availability of specific components or subsystems and permit to derive a correct initial deployment and guide the self-repair of the system. Additionally, we present our approach for worst case execution times estimation to predict software behavior in the time domain. Additionally, we describe our realization of these concepts in form of a CASE tool extension and a run-time framework. We report about the underlying concepts and the application of the plugin by means of an example. Development efforts for embedded software must consider the trade-off between fast development, maintainable code, correct as well as high-performance software.

I used Fujaba from UML to Java and back again for a lot of fujaba in my research and nowadays a lot in my teaching. The interpreter was initially presented in [5]. The architectural design is reused when designing the system architecture. Fault tolerance techniques as well as self-repair capabilities usually result in additional system complexity which can even spoil the intended improvement with respect to dependability.

In fujaba meantime, the interpreter evolved.

THe results were impressive and the feedback of the students very positive. We present an extension of ROOM that further fujaba service-based design and permits the independent validation of components for such a design style.

Finally, fujaba present a first evaluation of the developed architecture and its dynamic control of dependability. Our approach addresses fujaba problem and in particular the state explosion problem for the software controlling mechatronic systems, as we provide a domain specific formal semantic definition for a subset of the UML 2. Me and Artjom will provide here some screencasts and missing documentation to fujaba with Fujaba4Eclipse: The Alternate Editing Mode.


I took over two sessions of the Software Engineering Lecture: However, most approaches do not fully support the requirements for model synchronization today and focus fujaba on classical one-way batch-oriented transformations. I am currently writing a textbook on “Modeling with Objects” with Prof.

Fujaba steps prescribe how to compose complex software systems from domain-specific patterns which fujaba a particular part of the system behavior in a well-defined context.

Fujaba – From UML to Java and Back Again

fujabba A formal calculus including a notion of discrete-time automata, a deadlock preserving refinement notion, and a class of supported compositional constraints is developed.

If you fujabs interested in joining our team, please contact Holger Giese. However, the current MDA approaches and tools for hard real-time software do not provide fujaba ideal: As fujaba provides the most fujaba element in this concert of techniques, the integration of these different views often happens in the software.

Therefore, flexible means to store, query, and manipulate such context information are required. In this paper a seamless support of the whole service life cycle of service-based software architectures by means of Fujaba is presented.

To load Fujaba execute java -Xmx1g -jar fujaba. In this paper, we extend our fault tolerance pattern approach with additional fujaba degradation rules. Predictable real-time behavior w. Fault tujaba patterns are easily applied during the design of component-based systems to increase the reliability or availability of specific components or subsystems and permit to derive a fujaba initial deployment and guide the self-repair of the system.


A new field of research deals with the support of dynamic exchange of feedback controllers reconfiguration during design. Refer to the final ctr first and look up the fujaba construction parts in the fujaba. To support self-optimization it is not enough just fujaba permit to alter some free parameters of the controllers. The models which are used in design must enable to specify real-time behavior on basis of a semantics that allows an automatic synthesis of code which respects fujaba specified real-time requirements.

The focus of the fujaba is on enabling the design and simulation fujaba safe reconfigurable mechatronic systems, as reconfiguration is a critical prerequisite for self-optimization.

In order to keep this survey focused, we restrict our attention here to techniques and tools for the visual model-driven development of software intensive systems with focus on safety issues and integration of engineering concepts. Secondly, a new partitioning algorithm is outlined, which calculates an appropriate mapping onto a platform specific model by means of real-time threads with their scheduling parameters which fujaba be straight forward transformed to code for the hard real-time system.

Attention, there is a small mistake in this screencast. The consistency management is highly configurable and can be adapted individually to user, project or domain specific demands. During run-time the same restrictions are at first used to automatically map additional services on suitable nodes. The algorithm which partitions the model into threads and the corresponding code generation are also described in the paper and show how our approach supports automatic code synthesis.
