Institute of Architecture of Application Systems (IAAS)

Current Project

SimTech - Stuttgart Research Centre for Simulation Technology and Cluster of Excellence „Simulation Technology“: The SimTech project is developing scientific methods and applications in the different fields of modeling and simulation science. Within SimTech, the Institute of Architecture of Application Systems is concerned with the development of a workflow management system that is tailored to the requirements and needs of scientists. This system forms a platform for workflow-based automation of simulations considering increased flexibility and ease of use. Using this platform, simulation workflows can efficiently be modeled, executed, adapted, monitored and analyzed. One fundamental goal in the development of this system lies in hiding the technical complexity underlying the different phases of workflow-based automation of a simulation.

Previous Project

COMPAS - Compliance-driven Models, Languages, and Architectures for Services: The COMPAS project is designing and implementing novel models, languages, and an architectural framework to ensure compliance of services to design rules and regulations. COMPAS is using model-driven techniques, domain-specific languages, and service-oriented infrastructure software to enable organizations to develop business compliance solutions easier and faster. Compliance refers to the entirety of all measures that need to be taken in order to adhere to laws, regulations, guidelines, and internal policies. More information on COMPAS can be found on the project website, in the project brochure, the project poster, and in the final report.

PhD Thesis

Managing compliance in a service-oriented architecture requires, among other tasks, performing profound and traceable changes on process models and providing an according visualization for process management and auditing activities. For that reason I am defining methods and concepts for extracting, integrating, highlighting and fading out particular parts of a process (so-called process fragments) which are subject to compliance. My research has revealed that views on processes provide the fundamentals for this task. Therefore, I am investigating in my PhD thesis the application of process views in the field of compliance management in BPM. For instance, I investigate different techniques that can be used for the creation of views on processes (Process Viewing Patterns). As technical enabler for this approach I am developing tools like a repository for supporting efficient management of process fragments (Fragmento), a view-based framework for process instance monitoring (BPI), Web services for the generation of views, and a management framework for their composition. Some of these tools are freely available: Downloads

A view on a process intends to abstract from details and make complex processes easier to understand. A process view can be described as the outcome of particular transformations applied to a process model, for instance omission and aggregation of activities. Process views can be applied in several use cases, such as for providing a perspective on a process that is personalized for specific needs of a user, or for generating a public view on a process.
