--- _id: '39032' abstract: - lang: eng text: Executable UML models are nowadays gaining interest in embedded systems design. This domain is strongly devoted to the modeling of reactive behavior using StateChart variants. In this context, the direct execution of UML state machines is an interesting alternative to native code generation approaches since it significantly increases portability. However, fully featured UML 2.0 State Machines may contain a broad set of features with complex execution semantics that differ significantly from other StateChart variants. This makes their direct execution complex and inefficient. In this paper, we demonstrate how such state machines can be represented using a small subset of the UML state machine features that enables efficient execution. We describe the necessary model transformations in terms of graph transformations and discuss the underlying semantics and implications for execution. author: - first_name: Tim full_name: Schattkowsky, Tim last_name: Schattkowsky - first_name: Wolfgang full_name: Müller, Wolfgang id: '16243' last_name: Müller citation: ama: 'Schattkowsky T, Müller W.

A wide range of CSCW (Computer Supported Cooperative Work) tools with video conferencing, electronic mail, shared whiteboards, discussion forums, and shared information systems are already part of daily business. In contrast to the unstructured linear stream of information in electronic mails shared workspaces provide structured administration of electronic information like documents, voice, pictures, and movies. Popular examples of shared workspaces are BSCW (Basic Support for Cooperative Work), Hypernews, Lotus Notes, Alta Vista Forum, Lifelink, Microsoft Exchange and Webshare. Currently, all these systems are not flexible enough to get easily customized to the requirements of the individual application and user only supporting a limited set of predefined different views and functionality. This article introduces VIPspace (Visually Programmable Workspace). VIPspace can be easily customized to the individual needs of an user through VIPrule, a combination of a form- and icon-based visual programming language. VIPrule is based on an easy-to-use drag and drop paradigm. Direct manipulation via drag and drop allows easy access to local file systems as well as manipulation, exchange, and publication of shared multimedia documents. As VIPspace is implemented in Java it nicely integrates with other web-applications and provides a platform independent environment with a uniform graphical user interface. author: - first_name: M. full_name: Dücker, M. last_name: Dücker - first_name: Wolfgang full_name: Müller, Wolfgang id: '16243' last_name: Müller - first_name: Jessica full_name: Rubart, Jessica last_name: Rubart citation: ama: 'Dücker M, Müller W, Rubart J.

A SAM program is a set of interacting agents synchronously exchanging messages. The agent's behaviour is specified by means of production rules with a condition and a sequence of actions each. Actions are linearly ordered and execute when matching a rule. In SAM, main syntactic objects like agents, rules, and messages are 3D. These objects can have an abstract and a concrete, solid 3D presentation. While the abstract representation is for programming and debugging, the concrete representation is for animated 3D end-user presentations. After outlining the concepts of SAM this article gives two programming examples of 3D micro worlds and an overview of the programming environment. author: - first_name: Christian full_name: Geiger, Christian last_name: Geiger - first_name: Wolfgang full_name: Müller, Wolfgang id: '16243' last_name: Müller - first_name: W. full_name: Rosenbach, W. last_name: Rosenbach citation: ama: 'Geiger C, Müller W, Rosenbach W.

Fuzzy logic was introduced to directly support these applications (H. Zimmermann, 1991). Fuzzy control (FC) which is based on fuzzy logic allows one to control complex systems based on qualitative information like human knowledge (C. Geiger and G. Lehrenfeld, 1994). In fuzzy logic, fuzzy sets are usually defined and manipulated by means of complex mathematics, whereas the fuzzy control process is frequently outlined by visual sketches based on set diagrams in order to enhance the comprehension of the inference process. The rule based execution of this process usually follows the lines of rule based visual programming languages (VPLs), i.e., languages comparable to Agentsheets and ChemTrains. This strongly indicates that VPLs are thus well applicable for this use. We first outline the basic concepts of fuzzy logic and fuzzy control. Thereafter, we sketch a visual language which integrates fuzzy set diagrams in the visual representation of rules. The basic concepts are inherited from the complete visual programming language, Pictorial Janus (PJ). However, we significantly simplify PJ's visual concepts in order to adapt it for our purpose. author: - first_name: M. full_name: Dücker, M. last_name: Dücker - first_name: Christian full_name: Geiger, Christian last_name: Geiger - first_name: Georg full_name: Lehrenfeld, Georg last_name: Lehrenfeld - first_name: Wolfgang full_name: Müller, Wolfgang id: '16243' last_name: Müller - first_name: C. full_name: Tahedl, C. last_name: Tahedl citation: ama: 'Dücker M, Geiger C, Lehrenfeld G, Müller W, Tahedl C.

Kahn and V. Saraswat, 1990), for the modeling of complex systems and their control strategies. These systems can be seen as networks of communicating objects. Objects select strategies for suitable actions based on incoming messages. Our field of investigation is in computer integrated manufacturing considering the example of a car manufacturing cell. This color sorting assembly buffer (CSAB) schedules jobs in queues. The jobs represent car bodies scheduled in feeder lines for the enameling. Feeder lines collect raw bodies to blocks. Blocks are bodies which are to be enameled by the same color. This organization decreases the cost of expensive change-over-times when changing colors at the enamelling. Blocks of bodies are dislocated from the queue and enameled successively. Contradictory system goals, such as minimizing color changes and preserving the sequence of incoming jobs, have to be regarded by appropriate control strategies. Due to the complexity of this (NP complete) problem and to real time requirements for online control there are no optimal strategies on hand. Consequently, suitable heuristics have to be developed. Often they are designed applying a trial-and-error method. A modeling framework has to support the rapid prototyping of these systems as well as an expressive end user oriented representation. Both are essential requirements since end users need other visualization techniques than experienced designers due to their different knowledge and interests. author: - first_name: Christian full_name: Geiger, Christian last_name: Geiger - first_name: R. full_name: Hunstock, R. last_name: Hunstock - first_name: Georg full_name: Lehrenfeld, Georg last_name: Lehrenfeld - first_name: Wolfgang full_name: Müller, Wolfgang id: '16243' last_name: Müller - first_name: 'J.
