Queueing theory utilization in packet network design and optimization process
Rýzner, Zdeněk ; Zeman, Václav (referee) ; Novotný, Vít (advisor)
This master's thesis deals with queueing theory and its application in designing node models in packet-switched network. There are described general principles of designing queueing theory models and its mathematical background. Further simulator of packet delay in network was created. This application implements two described models - M/M/1 and M/G/1. Application can be used for simulating network nodes and obtaining basic network characteristics like packet delay or packet loss. Next, lab exercise was created, in that exercise students familiarize themselves with basic concepts of queueing theory and examine both analytical and simulation approach to solving queueing systems.

Vaccination center 4.0
Forejtník, Ondřej ; Uhlík, Ondřej (referee) ; Apeltauer, Tomáš (advisor)
The diploma thesis deals with modeling the pedestrian movement in a high-capacity vaccination center during the covid-19 pandemic. The subject of the modeling is the vaccination center that was operated by the Brno University Hospital at the Brno Exhibition Center in the first half of 2021. The work describes the vaccination process in the center and the related theory of pedestrian movement. A numerical model of the vaccination center was created in the Pathfinder program on the basis of data obtained, among other things, from the analysis of video recordings taken at the center. This was used for the capacity assessment of the vaccination center and for the creation of a design model of the center handling a higher intensity of incoming patients. The output of the thesis is a proposal for the layout of the vaccination center, which will allow the center to vaccinate the highest number of patients per day.

Application of Queueing Theory
VÁŇOVÁ, Eliška
The goal of this thesis was to understand Queueing Theory and use it for analysis of queueing system of hypermarket company PZV. Theoretical part is consists of basic iformations which is necessary to know for application of queueing theory. First chapter is about random variables, random event, random proces, stochastic and Poisson processes and Markov chains. Then was possible to describe queueing theory basic characteristics, parameters, analy-sis, classification and basic models. In the practical part was from the beginning analyze development of custo-mers going through cashier zone. On the base of analysis were customers divided into 4 groups. For these groups were counted characteristics and parameters, next was analyzed the system, but because data were too inaccurate, it was necessary to use different values for the groups and to count analysis for these values. The last step was to find number of cashiers to make system optimal. The result, it was 4 ca-shiers, was unfortunately not accurate. For better results it would be necessary to have more detail data.

Analysis and optimization of the Service Desk using BI
Gregor, Petr ; Novotný, Ota (advisor) ; Maryška, Miloš (referee)
The objective of this master thesis is to optimize a number of service desk operators in Atos IT Solutions and Services s.r.o. The thesis introduces a general and ITIL methodology definition of the service desk. The practical analysis section covers data mining in order to carry out an analysis and propose measures leading to optimal utilization of service desk employees. The method applied in the thesis allows a creation of service desk services demand predictions for any given period of time.

Simulační model dispečinku
Korecká, Markéta ; Kuncová, Martina (advisor) ; Dlouhý, Martin (referee)
Práce vystihuje teoretické poznatky z oblasti simulace a teorie hromadné obsluhy. Tyto poznatky jsou využity při zpracování praktického příkladu. Pro zpracování případové studie je využíván simulační software SIMUL8, pomocí kterého je vytvořen model. Cílem práce je namodelovat současný chod dispečinku, zjistit jeho úzká místa a po té pomocí experimentu s modelem navrhnout nutné rozšíření počtu pracovišť na dispečinku.

Simulace stochastických modelů hromadné obsluhy
Slámová, Kateřina ; Jablonský, Josef (advisor) ; Kuncová, Martina (referee)
Práce vystihuje teoretické poznatky z oblasti teorie hromadné obsluhy a simulace a následně jsou aplikovány poznatky do praxe. Pro případovou studii je využíván simulační software Simul8 a podpůrný program Crystal Ball, pomocí nichž je vytvořen model. Cílem je navrhnout nejlepší řešení daného problému a zhodnotit systém z hlediska struktury a funkčnosti. S modelem je provedeno několik experimentů a následně je posouzena vhodnost či nevhodnost použití jednotlivých variant.
