So genannte Risikomanagement-Informationssysteme (RMIS) unterstützen Unternehmen darin, ihr Risiko-Management unternehmensweit durchzuführen. Im vorliegenden Beitrag analysieren wir mit Hilfe der Scoring-Methode die inhaltlichen Anforderungen an ein RMIS und zeigen, wie das zu einer begründeten Auswahl für die Anschaffung eines RMIS führt. Dazu diskutieren wir erstens, welche Anforderungen an ein RMIS gestellt werden, zweitens klassifizieren wir die auf dem Markt existierenden RMIS bezüglich ihrer Anwendungsziele und drittens erstellen wir einen Anforderungskatalog und ein dreistufiges Verfahren zur Handhabung des Auswahlprozesses. Dieses wird im Rahmen einer erfolgreich durchgeführten Fallstudie im Rahmen einer Masterarbeit [11] in einem konkreten Konzern, der Telekommunikations- und Internetzugang anbietet (United Internet AG, Montabaur), erläutert und evaluiert. 1.
This paper describes the robot Lisa used by team homer@UniKoblenz of the University of Koblenz Landau, Germany, for the participation at the RoboCup@Home 2017 in Nagoya, Japan. A special focus is put on novel system components and the open source contributions of our team. We have released packages for object recognition, a robot face including speech synthesis, mapping and navigation, speech recognition interface via android and a GUI. The packages are available (and new packages will be released) on

Hybrid systems are the result of merging the two most commonly used models for dynamical systems, namely continuous dynamical systems defined by differential equations and discrete-event systems defined by automata. One can view hybrid systems as constrained systems, where the constraints describe the possible process flows, invariants within states, and transitions on the one hand, and to characterize certain parts of the state space (e.g. the set of initial states, or the set of unsafe states) on the other hand. Therefore, it is advantageous to use constraint logic programming (CLP) as an approach to model hybrid systems. In this paper, we provide CLP implementations, that model hybrid systems comprising several concurrent hybrid automata, whose size is only straight proportional to the size of the given system description. Furthermore, we allow different levels of abstraction by making use of hierarchies as in UML statecharts. In consequence, the CLP model can be used for analyzing and testing the absence or existence of (un)wanted behaviors in hybrid systems. Thus in summary, we get a procedure for the formal verification of hybrid systems by model checking, employing logic programming with constraints.
The lack of a formal event model hinders interoperability in distributed event-based systems. Consequently, we present in this paper a formal model of events, called F. The model bases on an upper-level ontology and pro-vides comprehensive support for all aspects of events such as time and space, objects and persons involved, as well as the structural aspects, namely mereological, causal, and correlational relationships. The event model provides a flexible means for event composition, modeling of event causality and correlation, and allows for representing different interpretations of the same event. The foundational event model F is developed in a pattern-oriented approach, modularized in different ontologies, and can be easily extended by domain specifific ontologies.
In recent years, traceability has been more and more universally accepted as being a key factor for the success of software development projects. However, the multitude of different, not well-integrated taxonomies, approaches and technologies impedes the application of traceability techniques in practice. This paper presents a comprehensive view on traceability, pertaining to the whole software development process. Based on graph technology, it derives a seamless approach which combines all activities related to traceability information, namely definition, recording, identification, maintenance, retrieval, and utilization in one single conceptual framework. The presented approach is validated in the context of the ReDSeeDS-project aiming at requirements-based software reuse.
Ziel dieser Forschungsarbeit ist die Auswahl und Evaluierung von Open-Source ERPSystemen auf effiziente Anwendbarkeit in Unternehmen zum Zwecke des Aufbaus eines "ERP-Future-Labs", in welchem mittelständische Handelsunternehmen das/die installierte(n) System(e) testen können. Den Projektabschluss bildet hierbei die Installation eines lauffähigen Systems, auf welchem die vom Auftraggeber vorgegebenen Geschäftsprozesse abgewickelt werden können. Ferner sollen die Auftraggeber auf dem System geschult, eine Dokumentation der Software (Installation/Bedienung) und des Projekts erstellt werden.
