Rationalization of the production line
Straka, Jiří ; Štipčák, Jaroslav (referee) ; Osička, Karel (advisor)
This masters thesis optimises production of the step plates (which are parts of the sliding steps systems used in tramways, subways, hi-speed trains etc.) to increase the production rate to meet customers demand. The purpose of the work was reached by detailed analysis of the production process followed by evaluation of the results which led to the list of the possible solutions. The solution with the greatest time improvement was chosen and explained in detail.
On the optimization of a production line in a mass production
Lyčka, Aleš ; Venclík, Milan (referee) ; Píška, Miroslav (advisor)
This diploma project deals with the production line in the selected company. The theoretical part is dealing with lean production, followed by the company description and description of the production line itself. The diploma project looks at the production line from a variety of perspectives and looks for the most appropriate points to optimize. The most important aspects are the efficiency of production and ergonomics. After finding critical points, different solutions are proposed and they are further elaborated, evaluated and the most appropriate one is recommended.

APPROACH TO REDUCING LEAD TIME IN MANUFACTURING SYSTEMS
Hromková, Ivana ; Škopán, Miroslav (referee) ; Šťastný, Jiří (referee) ; Mostýn, Vladimír (referee) ; Knoflíček, Radek (advisor)
Presented PhD thesis aims at development of new methodologies and approaches to reduce lead times in production systems. Therefore the thesis examines in detail the design of new, more comprehensive approaches to shortening lead times. The dissertation describes the methodology of using these approaches in production systems, it is suggested their inclusion in the control structure of production and adequate managerial support for the successful application of these new approaches in the industry is developed. The first part summarizes current knowledge in the field of reducing lead times. The various methods that can be used for reducing lead times are defined and described, from which is selected discrete simulation of manufacturing systems as a suitable method for the purposes of issue development. The next part of this work is therefore devoted to simulation approach to reducing lead times and the factors that affect them, such as processing time, size of the batch, queue lengths, etc. In this part is also discussed the use of information technologies (programming languages, libraries, and software tools) that enable efficient creation of simulation models. The second part is focused on industrial applications implemented to reduce production lead times. Specific simulation analysis deal with, for example, reduction of the lead time for manufacture of surgical instruments, screws, slats, but also transport systems, optimization of production orders input to the production system, the issue of supply, etc. The second part also describes a practical approach to data transfer to / from the simulation model, simulation software connection to the ERP database of enterprise and energy intensity of production. The conclusion summarizes the findings that were detected on the issue of reducing lead times, and within the chosen methodology, simulation of manufacturing processes indicates possible further progress in the research and practical applications.
Transformation of the simulation model from SW SimPro to SW Plant Simulation
Hloska, Jiří ; Štoček, Jiří (referee) ; Škopán, Miroslav (advisor)
This diploma thesis is based on creation of a simulation model of the conveyor bridge between a paint-shop and an assembly hall in the company Škoda Auto, a.s. in Mladá Boleslav. The model was created in the simulation software Plant Simulation on the grounds of an existing model in simulation software SimPro. Analysis of the existing model in software SimPro as well as a system analysis of conveyors used in the respected production section is carried out in the thesis. Results of simulation experiments accomplished with the newly created model follow. These experiments verify the throughput rate for various production programmes. On the grounds of these results a bottleneck analysis of the conveyor system is carried out and arrangements leading to increase in its throughput rate are made.

Šafářová, Jitka ; Němcová, Klára (referee) ; Videcká, Zdeňka (advisor)
Diplomová práce se zabývá návrhem procesů oddělení System Activation & Deactivation společnosti IBM Česká Republika, s.r.o. s cílem zlepšení těchto procesů a navýšení efektivity těchto procesů v rámci firmy.
Proposal for Waste Elimanation in the Ferrite Cores Production
Janec, Jiří ; Pavelka, Tomáš (referee) ; Videcká, Zdeňka (advisor)
The topic of this thesis is to optimize the production process of ferrite cores in the company Epcos, Ltd. The work is divided into theoretical, analytical and design part. The first part of the thesis contains theoretical knowledge within the field of lean manufacturing, process mapping and mapping value streams. Based on these findings is determined the theoretical basis for the processing of other parts of the thesis. The aim of the analytical part of the analysis is to map the current state of the manufacturing process, finding bottlenecks, evaluating the results of analysis of the current state, which will be used for the design part of the thesis, to develop proposals for optimizing production bottlenecks and evaluate their contribution.
Design Laboratory Phase Shifting Transformer
Korejčík, Michal ; Švec, Jan (referee) ; Paar, Martin (advisor)
This thesis deals with a power flow control in the electric power system. An overview of FACTS devices is introduced; their basic characteristics as well as examples of their application are discussed. A significant part of this thesis investigates phase shifting transformers (PST´s), which seem to be suitable for implementation in the transmission system of the Czech Republic. The PST´s are useful devices that control active power flows on cross-border lines and regulate unwanted and unexpected power flows. Basic types and characteristics of the PST´s are discussed. In chapter 7 is designed laboratory task that should validate the regulatory capabilities of the transformer PST. Designs of models of individual parts of this laboratory task are presented. In the last part of this thesis the regulation effect of the PST is validated in the GLF/AES program.
Analysis and optimization of the production system using computer simulation
Vaďura, Pavel ; Knoflíček, Radek (referee) ; Simeonovová, Ivana (advisor)
This bachelor thesis focuses on the process of the creation of a simulation model followed by dissimulation of this model, and finally optimalization of the system using the results of the simulation. The aim is to clarify basic terms about production with consequential usage of simulation models and their application in the production proces. Next, the creation of the simulation model in the simulation software Factor/AIM is explained and illustratively demonstrated. The first part of the bachelor thesis deals with theoretical information about the production proces, division and creation of the simulation model and it analysis this model with the purpose of finding narrow places and suggesting its optimalization. This simulation proces is simplified version of the manufacture of seamless pipes.
