  abstract     = {{Cyber-physische Systeme (CPSs) sind die nächste Generation von eingebetteten Systemen, die fortwährend ihre Zusammenarbeit koordinieren, um anspruchsvolle Funktionen zu erfüllen. Die Koordination zwischen ihnen kann in Software mittels asynchroner Nachrichtenkommunikation realisiert werden. Um die funktionale Korrektheit der Software zu gewährleisten, ist aufgrund der Kritikalität dieser Systeme eine formale Verifikation wie z.B. Model Checking notwendig. Die Eingabesprache eines Model Checkers unterstützt jedoch domänenspezifische Aspekte wie asynchrone Kommunikation nicht direkt, wodurch diese vom Softwareingenieur mittels zahlreicher Modellelemente spezifiziert werden müssen. Dies ist hochgradig komplex und somit fehleranfällig. Im Rahmen dieser Arbeit wird eine modellgetriebene Methode zur domänenspezifischen Spezifikation und vollautomatischen Verifikation der nachrichtenbasierten Koordination von CPSs präsentiert. Mit Hilfe dieser Methode kann der Softwareingenieur die Koordination kompakt modellieren und muss nicht länger verstehen, wie seine Spezifikation auf der Ebene des Model Checkers ausgedrückt wird. Insgesamt wird die Komplexität für den Softwareingenieur somit deutlich handhabbarer. Bezüglich der Spezifikation einer solchen Koordination definiert die Arbeit eine domänenspezifische Sprache namens Real-Time Coordination Protocols (RTCPs). Darüber hinaus wird eine domänenspezifische Sprache zur Spezifikation von Verifikationseigenschaften eingeführt und Entwurfsmuster für RTCPs präsentiert, um die Anzahl der Modellierungsfehler zu senken.}},

  abstract     = {{Distributed, software-intensive systems such as fully automated cars have to handle various situations employing message-based coordination. The growing complexity of such systems results in an increasing difficulty to achieve a high quality of the systems’ requirements specifications, particularly w.r.t. the realizability of the specifications. Scenario-based requirements engineering addresses the message-based coordination of such systems and enables, if underpinned with formal languages, automatic requirements validation techniques for proving the realizability of a requirements specification. However, formal requirements modeling languages require a deep knowledge of requirements engineers and typically require many manual iterations until they find a realizable specification. In order to support requirements engineers in the stepwise development of scenario-based requirements specifications, we propose to evolve a high-quality specification from a (presumably unrealizable) manually created specification employing an evolutionary algorithm. In this paper, we show our results on automatically evolving new assumptions on the systems’ environment behavior that guarantee a realizable requirements specification. Based on this contribution, we outline our research roadmap toward our long-term goal of automatically supporting requirements engineers in finding high-quality requirements specifications.}},

  abstract     = {{Moderne und Automatisierungs- und Produktionssysteme speichern viele schützenswerte Daten wie zum Beispiel Produktionsmengen oder Verfahrenseinstellungen. Sie werden von speicherprogrammierbaren Steuerungen (SPS) gesteuert. Eine SPS bietet eine Vielzahl von Netzwerk-/Datenschnittstellen. Insbesondere Schnittstellen zum Internet ermöglichen neue Funktionalitäten, sind aber auch mögliche Angriffspunkte. Neben einer Netzwerktrennung durch Firewalls sollte zusätzlich programmatisch unterbunden werden, dass auf kritische/sensible Daten direkt oder indirekt über einen kritischen, unerwünschten Datenfluss zugegriffen werden kann. Bereits während der Entwicklung einer Anlage kann der Steuerungscode mittels statischer Programmanalyse untersucht werden. Die unabhängige Analyse von einzelnen Programmen reicht aber bei vernetzten Anlagen nicht aus, da sich der kritische Datenfluss erst aus der Kombination von Programm- und Netzwerkverhalten ergeben kann. Deshalb stellen wir in diesem Beitrag erste Ideen für eine verteilte statische Analyse der Steuerungssoftware einer vernetzten Industrieanlage vor, welche es ermöglicht den Datenfluss der gesamten vernetzten Anlage zu betrachten. Hierdurch wird es möglich zu beurteilen, ob kritische/sensible Daten die vernetzte Anlage verlassen oder ob diese manipuliert werden können.

  abstract     = {{Original equipment manufacturers (OEMs) build mechatronic systems using components from several suppliers in industry sectors like automation. The suppliers provide geometrical information via the standardized exchange format STEP, such that the OEM is able to virtually layout the overall system. Beyond the geometrical information, the OEM needs additional technical information for his development tasks. For that reason, STEP provides an extension mechanism for extending and tailoring STEP to project-specific needs. However, extending STEP moreover requires extending several capabilities of all involved tools, causing high development effort. This effort prevents the project-specific utilization of the STEP extension mechanism and forces the organizations to use awkward workarounds. In order to cope with this problem, we present a model-driven approach enabling the flexible specification of STEP extensions and particularly the automatic derivation of the required further capabilities for two involved tools. We illustrate and evaluate the approach with an automation production system example.}},

  abstract     = {{The development of software-intensive technical systems (e.g., within the automotive industry) involves several engineering disciplines like mechanical, electrical, control, and particularly software engineering. Model-based Systems Engineering (MBSE) coordinates these disciplines throughout the development by means of a discipline-spanning system model. An integral part of MBSE is the requirements engineering on the system level. However, these requirements need to be refined for the discipline-specific development to start, for example, into specific requirements for the embedded software. Since existing MBSE approaches lack support for this refinement step, we conceived a systematic and iterative transition from MBSE to model-based software requirements engineering, which we present in this talk. We automated the steps of the transition where possible, in order to avoid error-prone and time-consuming manual tasks. We illustrate the approach and perform a case study with an example of an automotive embedded system.}},

  abstract     = {{Modern Cyber-physical Systems are executed in physical environments and distributed over several Electronic Control Units using multiple cores for execution. These systems perform safety-critical tasks and, therefore, have to fulfill hard real-time requirements. To face these requirements systematically, system engineers de- velop these systems model-driven and prove the fulfillment of these requirements via model checking. It is important to ensure that the runtime scheduling does not violate the verified requirements by neglecting the model checking assumptions. Currently, there is a gap in the process for model-driven approaches to derive a feasible runtime scheduling that respects these assumptions. In this paper, we present an approach for a semi- automatic synthesis of behavioral models into a deterministic scheduling that respects real-time requirements at runtime. We evaluate our approach using an example of a distributed automotive system with hard real-time requirements specified with the MechatronicUML method.}},

We jointly model financial distress by using two of its key driving factors: declining cash-generating ability and insufficient liquidity reserves. The model is based on stochastic processes and incorporates firm-level and industry-sector developments. A large-scale empirical implementation for US-listed firms over the period of 1980-2010 shows important improvements in the discriminatory accuracy and demonstrates incremental information content beyond state-of-the-art accounting and market-based prediction models. Consequently, this study might provide important ex ante warning signals for investors, regulators and practitioners.}},
