Implementation of SPC into the manufacturing process
Simandl, Martin ; Nikodým, Lukáš (referee) ; Bartes, František (advisor)
The diploma thesis focuses on the introduction of statistical process control in selected manufacturing company XYZ. It is divided into a theoretical and a practical part, while the theoretical part deals with theoretical knowledge of SPC methodology and quality management. The content of the practical part is the design and implementation of the measuring and evaluation station, which will be used for statistical control of the SPC process, into the emerging production of chip machining.

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.

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.

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.

Implementing SPC in the Production Process
Dostál, Petr ; Macháček, Martin (referee) ; Bartes, František (advisor)
The thesis deals with implementing of statistical process control (SPC) on CNC cut center into the mechanic production. One part of the project is engaged in theoretical information gathering, process monitoring and data collection. Second part deals with stabilization, regulation and improvement of the process using right statistical instruments. As a result is implementing measuring station from where will be the process data transferred to a server and evaluated. On the basis of that is possible to implement a correction in the right time if the process isn´t stabilized. The main objectives of the thesiss are cost reduction, scrap reduction and modernization of the process.

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.
