Simulation der Fahrplanerstellung auf der Basis eines hierarchischen Trassenmanagements und Nachweis der Stabilität der Betriebsabwicklung
This paper focuses on the further development of the asynchronous method to simulate timetable compilation and railway operation. The newly developed simulation strategy and the use of appropriate basic components introduced in the field of timetable compilation lead to a train priorities …

Rechnerunterstützte analytische Ermittlung der Kapazität von Eisenbahnnetzen
… The presented concept is based on the Queuing theory of operations research and used for the quantification of scheduled waiting time and dispatching delays within the railway network. Network is partitioned into investigation areas section route nodes and total route nodes. The …

Models and algorithms for ground staff scheduling on airports
… coarse-grained abstractions of workloads. If information on flights as well as passenger and load figures are sufficiently exact, we will rather be interested in directly covering individual work tasks. Furthermore, shift scheduling and rostering approaches have regularly taken special …

Leistungskenngrößen für Gesamtfahrstraßenknoten
… node. The new approach uses a multiresource queue from queuing theory to model a route node. Because of the multi-channel feature of a route node two or even more train runs can be operated simultaneously. To achieve the theoretical capacity of the system, train runs have to be arranged …
