This course will be in English.

 

Dieser Kurs wird auf englisch gehalten.

Wir beschäftigen uns mit den grundlegenden stochastischen Modellen, die zur Untersuchung der Leistung von Computersystemen häufig benutzt werden. Markov modelle und Warteschlangen werden gerne für die Untersuchung dynamischer Systeme verwendet, z.B. Computer Hardware, Kommunicationsprotokolle, biologische Systeme, Epidemien, Verkehr und digitale Währungen.  Wir werden uns einen raschen Überblick verschaffen.  Betrachtete Themen sind der Geburts- und Todesprozess, der Poissonprozess, verallgemeinerte Markov und semi-Markov prozesse sowie deren Lösungsmethoden. Soweit die Zeit es erlaubt werden wir auch die Hintergründe der diskreten Ereignissimulation ansehen.

Lecture Materials:

This lecture will be on site and in presence. However, last years videos and materials exist and can be used, if you miss a lecture. There is no guarantee that we will cover exactly and only this material.
