Empirical studies showed that many types of network traffic exhibit long-range dependence (LRD),i.e., burstiness on a wide variety of time-scales. Given that traffic streams are indeed endowed withLRD properties, a next question is: what is their impact on network performance? To assess...

Parkinson's law states that work expands to fill the time available for its completion and that the number of administrators in an office is bound to increase over time. An unique laboratory to test Parkinson's ideas are vehicle registration offices in Germany. Using their data we found...

In this article, a special case of two coupled M/G/1-queues is considered, where two servers are exposed to two types of jobs that are distributed among the servers via a random switch. In this model, the asymptotic behavior of the workload buffer exceedance probabilities for the two single...

We report an empirical analysis of the responses of the supply and demand for secondary care to waiting list size and waiting times. Whereas previous empirical analyses have used data aggregated to area level, our analysis is novel in that it focuses on the supply responses of a single hospital...

Hintergrund: In Deutschland werden die Wartezeiten auf medizinische Dienstleistungen öffentlich und ordnungspolitisch immer wieder problematisiert. Dies gilt vor allem für den niedergelassenen Ärztebereich. In der vorliegenden Arbeit wird erstmalig der akutstationäre Sektor analysiert....

Von Lichtsignalsteuerungen, die vorrangig auf das lokale Verkehrsgeschehen vor Ort reagieren, sind einerseits positive verkehrliche Wirkungen zu erwarten. Eine ausgewogene ÖV-Beschleunigung gehören ebenso dazu wie eine flexible Kolonnenführung in Form dynamischer Grüner Wellen. Andererseits...
