Production process optimization
Habásko, Jakub ; Koška, Petr (referee) ; Fiala, Alois (advisor)
HABÁSKO Jakub: Production process optimization. The Master´s thesis of Master degree, second grade, school year 2008/2009, FME Brno University of Technology, Institute of Metrology and Quality Assurance Testing, October 2009, pages 68, pictures 40, tables 2, supplements 4. The project elaborated in frame of the Master degree, study branch Metrology and Quality Assurance Testing. This Master´s thesis deals with optimization of process plan. In virtue of submission was created an analysis present condition using of statistical methods and it was created suitable statistical methods applicable in production organization. Then is here described the problem of brazing bells, because in this place is originating the most of uptightness. Then the thesis brings recommendation and findings, which can help with optimization this process.

Study of implementation of SPC statistical method for control of technological operations
Ondruška, Jan ; Zeman, Karel (referee) ; Jurová, Marie (advisor)
The master’s thesis contains a procedure of implementation of statistical process control for a machining process in a chosen company. The method is based upon knowledge of this topic which are mentioned in the first part of the thesis. The output is a comparison of general process performance before and after implementation of the above-mentioned statistical method and evaluation of the influence of this new method at the process. The comparison is done using hypothesis testing of specific statistical variables and analysis of process performance and capability of both data sets. The acquired knowledge and experience will be used for implementation of statistical process control for other processes in the company’s production portfolio.

Usage of Statistical Methods to Assure Capability of Production Process
Peroutka, Michal ; Pelánek, David (referee) ; Doubravský, Karel (advisor)
The diploma thesis deals with usage of statistical methods to assure capability of production process. The theoretical part includes the definition of quality management, basic statistical concepts and statistical process control. The practical part presents basic information about the company P & L, spol. s r. o. and analyzes the production process of selected parts. The tools of statistical process control are applied and measures to assure capability of production process are proposed.

Stability of the production process of railway base plates.
Szmek, Tomáš ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The master’s thesis is focused on process monitoring using statistical process control SPC tools. It is designed as a guide for the implementation and use of control charts in the manufacturing process of the base plates, which would ultimately be conducive to improving and stabilizing the process. The theoretical parts are the basic attitudes and practices methodology of SPC, especially classical Shewhart control charts. The next section describes the current status in Strojírny Třinec, a.s. and the manufacturing process of the base plates. Followed by application of control charts for a given quality features and analysis using statistical software. Based on the evaluation are findings and recommendations for long-term monitoring of the defined quality features.

Scrap Analysis in Manufacturing Process
Buriánková, Alena ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
The master’s thesis is focused on the reduction of rejection rate in production of plastic bowls with the use of statistic methods. The theoretical part of this thesis describes among others Statistical Process Control, Process capability and types regulatory diagrams. The basis for the practical part is data collection over a certain period of production, from which the percentage of the rejection rate is evaluated. Experiments and corrective actions are designed to improve the process and thereby reduce scrap.

Quality management tools
Zachová, Zuzana ; Levek, Vladimír (referee) ; Novotný, Radovan (advisor)
This bachelor thesis deals with methods, and above all with quality management tools. It consists of four parts. In the first part of the thesis is briefly presented the history of approaches to quality management. In the second part, a basic overview of the seven basic tools for quality control is elaborated and in the case of those tools, which are statistical, the procedure of their construction in Minitab is outlined. In the third part are processed advanced statistical tools with a focus on the analysis of the measurement system. In the fourth, practical part, selected methods of analysis of the measurement system are analyzed by case studies.

Use of Statistical Methods for Data Processing
Hladiš, Lukáš ; Ing.Churý Tomáš (referee) ; Doubravský, Karel (advisor)
This thesis aims to evaluate a new manufacturing process by using statistical methods SPC. In the theoretical part provides the basic methods and rules applied in the assessment of control charts. The next part evaluates the current state of the company Hanhart Morkovice s.r.o. analysis and production of coils. The analytical part deals with control charts for reference and quality characters using statistical software process capability indexes and control charts. Based on information from the analytical part, conclusions are drawn and designed for long-term steps using established methods of SPC for quality characters.
