Processes Improvement in the Mechanical Engineering Production
Hodulík, Lukáš ; Chovanec, Peter (referee) ; Videcká, Zdeňka (advisor)
The bachelor's thesis focuses on improving the process of material control in relation to the production process in a selected company engaged in the production of aerosol cans. The proposal based on the analysis of the material control process applies the AQL method and the Brinell hardness testing for the input control of the material and presents the methodology for improving the quality of the process. The developed proposal should lead to a quality defects reduction and the improvement of supplier-customer relations.

Reliability assessment of the Safety Helmets Manufacturing Process
Kartali, Csaba ; Rozehnalová, Jana (referee) ; Blecha, Petr (advisor)
The theoretical part of this master thesis lists all the necessary prerequisites which are needed in order to carry out a full and comprehensive reliability assessment of any given process. To do so it provides an overview of reliability in general, mathematical and statistical guidance together with a more detailed picture of the application and description of the process by quantifiable indicators. Furthermore it gives an overview of two important analysis tools, such as FTA and FMEA, accompanied by the basic principle and summary of the Six Sigma methodology and tools. The practical part of the thesis deals with the detailed description, quantification and goals of the process of safety helmet manufacturing and testing in order to be able to carry out a suitable assessment of the reliability by using the necessary set of tools and methods in order to identify the failures and their causes in the process by addressing them with suitable means of changes and corrective actions.

Možnosti zefektivnění procesu realizace víceprací ve výrobním podniku
Indrová, Tereza
The diploma thesis deals with the possibilities of making the process of realization of the multipurpose process more efficient, in the sense of dismantling of defective parts and return of the perfect parts back to the production process in the automo-tive industry. In the theoretical part of the diploma thesis there are laws and norms related to the automotive industry, including the applied methods in this industry with real researches in many companies all over the world. The following section introduces XYZ and its products. Follows the current process of disman-tling defective parts, Paret analysis with the Lean Six Sigma method. On the basis of analyzes and methods for streamlining the training workplace, one of the options for streamlining the process of implementation of the multi-site training at the XYZ training workplace.

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.

Draft measures to reduce customer complaints
Charvátová, Petra ; Strnad, Vlastimil (referee) ; Tyráček,, Petr (advisor)
This diploma thesis deals with customer complaints of headlamps in Automotive Lighting s.r.o. The goal is to analyze the state of customer complaints for 2018 and to evaluate the biggest source of nonconformities in terms of the type of complaint based on Pareto analysis. The thesis focuses on solution of one particular type of complaint. The key part of the thesis is also the processing of the process analysis, the evaluation of the causes of the complaint and the draft of corrective measures that would eliminate the problem. The conclusion of the thesis contains evaluation of the proposed corrective measures, including from the economic point of view.

Proposal to Improve Business Project Management Processes
Klapková, Anna ; Antoš, Michal (referee) ; Juřica, Pavel (advisor)
This bachelor thesis focuses on project management in a company of choice. Its aim is to create suggestions for improvement of the processes used by project managers of the chosen company. The analysis deals with managers' open answers to a survey. These answers are processed through a Thematic analysis and Pareto analysis. The results of these analyses identify possible drawbacks and rooms for improvement in areas discussed in the survey. The result of the thesis should be the suggestions leading to the improvement of the processes used by project managers.

Statistical analysis of defects in construction practice
Luska, Zbyněk ; Hlavsa, Tomáš (advisor) ; Michal, Michal (referee)
This thesis on statistical analysis of defects in construction practice deals with the assessment of defects which are monitored within the system of construction and technical prevention in the period from 2010 to 2013. We cannot consider as defects such matters arising from non-compliance with the contractual relationship between the sponsor and implementer of the building work, and that this does not contradict the building Act. This thesis aims to determine the defects in construction practice and the right tools, statistical analysis, and quality control methods to assess the state and evolution of defects, as well as to find links and dependence of defects on defined factors. The methodological part of the thesis is based on an exploratory statistical analysis of qualitative data, Pareto analysis, and also statistical testing of the hypothesis of independence using the chi-square test of independence in the pivot table. The strength of any relationship is tested under Cramér V. The output of the thesis is a list of the most frequently occurring defects in construction practice, a description of the defects, and their evaluation in terms of occurrence in time, within a defined territory, and the occurrence of a specific building construction.

Use of Pareto analysis for production data processing
Ručka, Petr ; Ošmera, Pavel (referee) ; Pásek, Jan (advisor)
This bachelor's thesis deals with the realization of Pareto analysis in the system COMES Modeller. The first part describes the Pareto analysis and Lorenz curve, together with instructions, how to properly apply the Pareto analysis on data obtained from the manufacturing process. Furthermore, they are also mentioned other methods, which have applications in industry. Pareto analysis is then compared with them. The second part of this thesis focused on the system COMES and design implementation and realization Pareto chart in this system.
