Improving material flow by using a logistics train
Grepl, Radovan ; Urbanovský, Jan (referee) ; Zeizinger, Lukáš (advisor)
The main content of this master´s thesis is the analysis of the current state and the proposal an internal supply of assembly lines in the company Koyo Bearings s. r. o. This company specializes in the production of bearings mainly for the automotive industry. The supply of the lines operates on the principle of Mikl-run. The practical part focuses on creating a simulation model using the Plant Simulation simulation software from Siemens PLM Software. Based on the created model, several variants were proposed to optimize the loading of the packaging material. These variants were analyzed and evaluated.

Long-distance belt transport
Řepa, Vojtěch ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
The bachelor's thesis deals with long-distance belt transport, the principles of which are explained in the first chapter of the thesis. In the following chapter, the individual components of the belt conveyor are described in detail. The practical part of the bachelor thesis deals with the conceptual design according to the specified parameters in accordance with ČSN ISO 5048 and the professional literature on the construction of belt conveyors. To verify the correctness of the concept, the strength of the selected conveyor belt is checked. A 3D visualization and drawing documentation of the conceptual design is created for the proposed concept.

Using optimization methods to design machine parts
Kubrický, Daniel ; Pokorný, Přemysl (referee) ; Zeizinger, Lukáš (advisor)
This bachelor thesis describes using structural optimization methods to design machine parts. In the first part of the thesis, a description of the current state of knowledge of the optimization process was made together with its theoretical background. In the second part of the thesis, a static analysis and topology optimization or Generative design was developed using the example of a bell crank in six commercial software. In the third part, the resulting models of each software were compared with each other, and the results were compared using the von Mises maximum stress criterion and the overall model deformation. Finally, this work was concluded with an evaluation of the use of the structural optimization software.

Material flow concept of a production line supply
Sedláček, Petr ; Dorušáková, Kamila (referee) ; Zeizinger, Lukáš (advisor)
The content of this thesis is a research analysis of individual concepts in the field of corporate logistics with an emphasis on intra-company transport. In the practical part, the current state of the production line loading is evaluated and new variants of line supply are made on the of the given parameters. The work also includes the creation of simulation models of all variants in the Plant Simulation program and conclusions are drawn based on the data obtained.

Long-distance belt transport
Baričiak, Petr ; Kašpárek, Jaroslav (referee) ; Zeizinger, Lukáš (advisor)
The bachelor thesis deals with the calculation and design of a conveyor belt with a transported quantity of 3 500 t/h with a length of 300 m and an elevation of 22 m. The introductory part is devoted to detailed research of individual components of belt conveyor. In the following chapters, a functional calculation according to ISO 5048, strength check of the shaft, bearings of the driving pulley and conveyor belt is performed. The last part of the thesis describes the choice of parts, which was based on strength and calculation chapters. The result of the entire thesis is the drawing documentation containing the drawing of the assembly.

Lifting equipment for handling the repair
Bednář, Vojtěch ; Zeizinger, Lukáš (referee) ; Škopán, Miroslav (advisor)
The bachelor's thesis is focused on lifting equipment that are used in smaller repair shops and services. In the first theoretical part, a survey of currently used and industrially produced workshop lifting equipment is carried out. In the second part, the design of the workshop gantry crane verified by functional and dimensional calculations is described, and finally the structural solution supplemented by the drawing documentation of the crane.
