Traffic routing is a well established optimization problem in traffic management. We address here dynamic routing problems where the load of roads is taken into account dynamically , aiming at the optimization of required travel times. We investigate ant-based algorithms that can handle dynamic routing problems, but suffer from negative emergent effects(More)
The decomposition of planning and scheduling problems is awell known technique to maket hese problems tractable. The resulting dependable subproblems were often solved using different planning systems. In this article we focus on an example from the container terminal management. We point out the dependencies between the planning systems. Using asubset of(More)
Gestational diabetes is a type of diabetes affecting temporarily some otherwise healthy pregnant women. Current medical practices do not allow the doctors to monitor such patients as closely as needed. Pervasive Health is a discipline requiring distributed ICT infrastructures to help bridging the gap between the patients and the doctors. In this demo paper(More)
Actual control and decision support systems rely more and more on distributed software systems. A central aspect in the design of these systems is the selection of an appropriate level of local autonomy of these subsystems in the decision making process. Most of the research focuses on the regulation of these entities towards an integration of centralized(More)

The reuse of code and concepts is an important aspect when developing multiagent systems (MAS) and it is a driving force of agent-oriented software engineering (AOSE). In particular, the reuse of mechanisms like coordination is fundamental to support developers of MASs. In this article we address the selection of effective and efficient mechanisms to(More)
Teaching Artificial Intelligence (AI) or multi-agent systems is a challenging task as algorithms are in question which are advantageous in highly complex and dynamic environments. Explaining multi-agent systems (MAS) in lectures requires interactive approaches accompanied by exercises. The key challenge in using practical exercises within lectures on MAS is(More)
