Operation measurement optimization
Barták, Pavel ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
This diploma work is aimed to measuring process, by measuring laboratory, during serial productions in international company Bosch Diesel s.r.o. Jihlava producer of common rail. Target of this diploma work is cross-check of evaluated dimensions, reengineering of incomming parts flow from production to measuring laboratory, measuring process, evaluation of results and pass results back to production. This will speedup all process and minimalist risk of production not O.K. products because of latest results from measuring laboratory. Is done analysis of present situation and base on it proposed different variants of solutions for reengineering of measuring laboratory.

Measurement management system
Aichler, Jaroslav ; Doňarová, Jana (referee) ; Koška, Petr (advisor)
The subject of diploma thesis is analysis of the European Standard EN ISO 10012, which has a status of a Czech Standard (ČSN EN ISO 10012). It’s focused on roughness measurement. The thesis was written in cooperation with a private company called PLASMAMETAL Ltd. situated in Brno. The company offers coating applications for a variety of materials. Important part of the thesis is a measurement management system improvement manual for PLASMAMETAL Ltd. It’s also dealt with the economical aspect of an investement into a new measurement equipment.

Value stream analysis
Perutka, Michal ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
The aim of the diploma thesis “Value stream mapping” is to analyse the montage workplace of the company IFE-CR, a.s. with focus on the value stream and the methods of lean production. The thesis aims to identify priorities for applying lean production methods at the montage workplace and to propose concrete measures in order to reduce different types of wasting. The first part of the thesis is dealing with the theory, understanding the main principles and methods of lean production, as well as with the method of value stream mapping. The second part is dealing with value stream analysis of the montage workplace and proposes concrete measures to reduce wasting and to increase the production effectiveness, respectively to improve the material stream trough implementation of selected lean production methods in the montage workplace.

Reduction of scrapping in ZR projects
Urbanová, Simona ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
The diploma thesis deals with reduction of scrapping at zero rework projects. These are the projects where corrections of particular parts are not allowed. If there are any in this way damaged parts, the entire products become scraps. Due to the fact the cost of low quality is increased, which is undesirable. The theoretical part describes the use of the six sigma method, which is then applied in the practical part. By using the IPO analysis the possible causes of the main problem have been chosen and then tested. The output of the diploma thesis is to find out and eliminate the causes of discrepancy, especially bridge walls at zero rework projects. After implementation of the first arrangements the scrapping has already been reduced.

Technical standards for quality
Plíštilová, Petra ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
This research deals with the development of technical standards from the past to the present and standardization in the Czech countries. Labeling and distribution of technical standards and their adaptation to European legislation is in the next part of the Bachelor´s thesis. It continues with other steps of the conformity assessment of products according to legal regulations and standards. Finally the thesis describes the CE marking and the requirements of its location on prescribed products.

Optimization of production process
Olšák, Jiří ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
The aim of this thesis is to reduce the cost of poor quality in the chosen production process. Specifically I focused on the winding lines at the production of rotors, which are components of electronic brake systems (EBS) and heating and ventilation systems of cars. The thesis was worked out in accordance with an announced Six Sigma project in the company. I also dealt with the Six Sigma strategy in the theoretical part. The chosen tools are applied afterwards in the practical part, especially in define, measure and analyse phases. The output of this thesis is an analysis of all possible causes of high scrap ratio in the stated production process. I also proposed to adopt measures for cutting the cost of poor quality in the chosen production process.
