In computer science the notion of adaptive systems has been used in different contexts for many years now. Although there is some intuitive, common understanding of the notion, a precise and universally practicable definition is still missing. More precisely, previous definitions fail to strictly differentiate between adaptive and non-adaptive systems. We(More)
—Autonomic Computing (AC) is an emerging paradigm aiming at simplifying the administration of complex computer systems. Efforts required to deploy and maintain complex systems are usually high. Autonomic Computing may help to reduce these efforts by allowing administrators to define abstract policies and then enable systems to configure, optimize and(More)
This paper considers the behavior planning of robots deployed to act autonomously in highly dynamic environments. For such environments and complex tasks, model-based planning requires relatively complex world models to capture all relevant dependencies. The efficient generation of decisions, such that realtime requirements are met, has to be based on(More)
Today's software systems tend more and more to comprise a multitude of different, often interfering functionalities. Especially in the case of embedded systems with their high requirements on safety this imposes additional risks for unwanted system behavior. Use cases are a common way to describe system functionalities in very early phases of the system(More)
