research overview

The chair for Economics and Computer Science concerns itself in the research with concepts of the economic controlling of large, distributed information systems in economic application environments with real time requirement. The visions of future information systems 21. Century (key words are Ubiquitous Computing, Pervasive Computing, Smart Environment) are occupied with smallest processors, which interact with one another high-interlaced over wireless communication ways. The net is the computer - the devices will be invisible for our eyes and with the physical environment "will verwoben", e.g. as RFID chips in articles of clothing, furniture, walls or medical instruments. Processor time and storage location are referred if necessary from the net, similarly as in the today's electricity net (Grid Computing, Peer ton Peer Computing). Small, passive devices with hooking leagues user interfaces and the constant need of human intervention during an interaction will wake a demand for autonomous and per-active software components. Such software agents support human buyers and salesmen during e-Commerce-processes, in order to lower transaction costs. These processes are characterized by negotiations and money transactions. Many will take place not over the InterNet, but locally, directly between the devices. Digital business agents (digital Business Agents, DBA) observe continuously different agents and their environment, e.g. by constant price comparisons between offerers in the on-line and off-line world, in order to fulfill a goal of the use maximization for their human owner. But they can negotiations with many potential trade partners at the same time accomplish and within milliseconds to an acceptable conclusion come. Thus it is possible that DBAs complete complete business transactions in the background, without which humans intervene must. These high-dynamic, adapting processes are a central component silent of the Commerce and/or the Supply chain Event management. In itself the information systems resulting in from it a control can take place only to the smallest part over central control procedure. Procedures of the self organization move therefore into the center of the interest, how they are the basis e.g. for the biological evolution, social group behavior and market dynamics (Katallaxie of F.A. von Hayek). For draft and control large computer systems are necessary such procedures (see Autonomic Computing), in order to go around the restrictions of today's information systems, like e.g.. Skalierbarkeitsprobleme, high maintenance costs and small adaptability.
