VIRTUAL FACTORY USING MATHEMATICAL PROGRAMMING METHODS
Svoboda, Jan ; Sklenář, Jaroslav (referee) ; Mauder, Tomáš (advisor)
This work is focused on solving problems in Industry 4.0. Main part of this work describes development of a discreet simulation model based on queuing theory. This model will be used for a heuristic optimization of a production line. Model will be validated with data from real production line. Improvement of effectivity using discrete model and heuristic optimization will be shown on virtual production line.

Queuing theory and virtual factory by using mathematical models
Myška, Martin ; Klimeš, Lubomír (referee) ; Mauder, Tomáš (advisor)
This thesis deals with the modelling of a production line. The topology of the line is based on the real production line of BOSCH DIESEL s.r.o. – Jihlava company. Simulations have been made using Matlab-Simulink-SimEvents software. The created model represents a pilot simulation of the manufacturing process. The model allows to set a deterministic or stochastic approach and use of an auxiliary worker for planning machine maintenances and finding the bottlenecks in the production. As a pilot version the model is simplified, e.g. the short breaks of operators are neglected. The simulation results and comparisons are described in detail later in this document. In order to bring the simulation closer to the real manufacturing process, future improvement options are mentioned.

Queuing Systems of Active Networks for Controlled Packet Sending
Vala, Ondřej ; Jeřábek, Jan (referee) ; Koton, Jaroslav (advisor)
This bachelor thesis is describing queueing systems to provide quality of services in telecommunication networks. The work consists of a theoretical and practical part. The theoretical part describes the types of algorithms, which are used in active components and protective mechanisms against queues congestion. In the practical part, there is the analysis of the real Matlab-Simulink model. The last chapter of the practical part is devoted to the comparison of all the systems in terms of packet loss and packet delays in queues at constant input intensity of data streams.

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 operational research methods in selected company
Bílková, Jitka ; Kvasnička, Roman (advisor) ; Horáková, Tereza (referee)
This bachelor thesis discusses Queuing models one of many disciplines of operational research. At the beginning of theoretical part is introduced operational research and briefly described different disciplines. Then there are described queuing models and laid the theoretical basis, in which are explained main characteristics of queuing models. At the end of theoretical part is mentioned how to classify queuing models.
In the practical parts is selected problem which will be solved using queuing models. This problem is servicing customers at the branch of company Česká pošta. From the obtained information is created queuing model, which is classify as M/M/c according Kendalls classification. On the created systems are applied analytical calculation and used simulation model. For simulation is used program MS Excel and randomly generated numbers. Process of creating simulation model is continuously recorded. Simulation model is running for 5000 customers to ensure that the results have adequate explanatory power.
The created simulation model is found to be invaluable at the final comparison of results obtained from both approaches. Simulation model provides more information, that in analytical model are not available. These additional valuables information are use for the closing recommendation.

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.

Customer service in a gym
Těšínská, Anna ; Kořenář, Václav (advisor) ; Šindelářová, Irena (referee)
The aim of this thesis is to summarize the basic knowledge on the subject of queuing theory and to suggest ways of their use in practice. The theoretical section describes the basic queuing models, as well as their characteristics and classification. In specific the simple exponential model and the exponential model with a parallel service. The thesis also explains and describes utilization of two softwares (STOCHASTICA and STORM), that are used to calculate basic characteristics. In the practical part, the thesis focuses on handling customers in Prague's gym Hit Fitness Flóra. Apart from analyzing the obtained data about the numbers of served customers, there is also a description of the optimization procedure on this queuing model, using the two mentioned softwares STORM and STOCHASTICA.
