About the AIS group

The Architecture of Information Systems (AIS) research group investigates methods, techniques and tools for the design and analysis of Process-Aware Information Systems (PAIS), i.e., systems that support business processes (workflows) inside and between organizations. We are interested in these information systems, their architecture, and innovative techniques to model and analyze the business processes and organizations supported by such systems.

Our mission is to remain one of the worldwide leading research groups in process modeling and analysis, process mining, and PAIS technology. We aim at results that are highly original and applicable in real-life situations. Our motto is

“Process Technology that Works”

The research concentrates on formalisms for modeling and methods to discover and analyze models. On the one hand formal methods are being used, e.g., the group has a long tradition in Petri-net modeling and analysis. On the other hand, we are interested in modeling languages widely used in industry (BPMN, EPCs, UML, BPEL, etc.). In contrast to many other research groups we do not accept a model as an objective starting point, i.e., we also try to discover process models through process mining and check the conformance of models based on reality.

The AIS group tries to make research results accessible by providing (open-source) software. Notable examples are ProM (process mining and process analysis), YAWL (workflow management), and CPN Tools (model-based analysis, simulation). These implementation efforts illustrate that the problems of tomorrow’s practice are the driving force behind the development of new theory, methods, and tools by AIS.
