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)
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)

In this article we describe a practical planning problem, the potted plant packing problem, and our first approaches to solve this problem. The transportation of plants is comparably expensive as they require careful treatment due to there sensitivity. For standardised transport, potted plants are loaded on transport trollies. The cost of transportation(More)
