Root cause analysis of scrap during production of bearing rings in a roller bearing company
Studýnka, Pavel ; Marek, Tomáš (referee) ; Marek, Jiří (advisor)
This diploma thesis concerns about measuring of rings of bearings from the input material, throughout machining processes, such as turning, heat treatment, grinding, till finishing operations as honing. Purpose of this thesis is to map all the processes in a roller/needle bearing company, measuring of rings of bearings, evaluating data, propose actions leading to decrease the number of scrap product and technical-economical evaluation of changed processes.

Jidoka system review
Turková, Daniela ; Musil, Martin (referee) ; Fiala, Alois (advisor)
The goal of this thesis was to devise appropriate improvements for the quality control tool JIDOKA used in Continental Automotive Systems Czech Republic s.r.o based in Frenštát pod Radhoštěm. First, three areas of concern requiring improvement pro-posals were identified. These were: visualization of the maximum amount of rejects, physical handling of rejects and documentation updates. This work comprises an introduction to the issue and the company, application principles of JIDOKA in Continental company and a description of the areas of concern. As a conclusion, solution proposals for given areas and their implementation are presented.

Proces Improvement in Manufacturing
Hasmanová, Sabina Bohdana ; Mouralová, Kateřina (referee) ; Juřica, Pavel (advisor)
The object of this thesis is eliminating scrap in the manufacturing process using Lean Six Sigma methodology combined with other supporting elements. The aim is to ensure that such business conditions to avoid all non-conforming products. The work is based on the basic theoretical knowledge, followed by analysis of the current state of business. In conclusions are evaluated the measures accepted by the company and overall efficiency of executed changes.

KAIZEN Application
Brhlík, David ; Kotek, Luboš (referee) ; Fiala, Alois (advisor)
The goal of thesis is to implement Kaizen method into manufacturing process and so mineralize the scrap of production and at the same time get an numerical overview of the guarantee for the quality of product. Implementation this method will lead to elimination of existing random check of the process. Place: ABB s.r.o. Brno (company is specialized to production switchgears)

Proposal to Reduce the Non-conformance Rate in the Manufacturing Process
Hamr, Zdeněk ; Lapeš, Ondřej (referee) ; Videcká, Zdeňka (advisor)
This bachelor´s thesis deals with a proposal to reduce the non-conformance rate in the manufacturing process. It contains three process optimization proposals to minimize scrap. The work is divided into three main parts. The first part is theoretical dealing with theoretical concepts. The second part contains a global and detailed analysis of production with identification of the main problems. The third part includes a design solution based on the analytical part.

Statistical Process Control and Reduction of Scrap
Negrová, Stefania ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
The aim of the diploma´s thesis is analysis of the scrap of the chosen process, using the tools of statistical process control and proposal of appropriate containment to reduce the scrap. The thesis describes all seven basic tools of quality and the greatest attention is aimed to Shewart's control charts. One chapter discusses three methods of problem solving in technical practice, while one of the described methods is used in the practical part of the thesis.

Entrepreneurial Project
Svobodová, Petra ; Novák, Zdeněk (referee) ; Rompotl, Jaroslav (advisor)
This bachelor thesis deal with the design of the entrepreneurial project, which will be use for execution of a project in production part of industrial plant. Target of the project is minimalization of production time and elimination of scrap in production process of chooses clips. First I started with principles. After principles I introduce analyze of the project by different methods. In last part I proposed procedure is for successful implementation of project including economic evaluation.

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.
