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.

Data processing from measurement on machine tools
Pokorný, Zdeněk ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
The Master’s thesis deals with the precision of machine tools, especially with the three-axis vertical milling machine. It is structurally divided into a theoretical and practical part. While the theoretical part focuses on problems of geometric errors and measuring devices, the practical one is devoted to the machine tool being tested. In this case, the data processing and the proposed statistical analysis are essential, and at the end of the thesis another possible way of developing the data processing is outlined.

Software Development Processes Metrics
Verner, Jan ; Bartík, Vladimír (referee) ; Kreslíková, Jitka (advisor)
The importance of processes is growing. Processes are integrated into many areas of human work, where they help to organize all activities. This thesis aims on statistical approach to process behavior analysis. There are mentioned the basic process management issues in the beginning of this thesis. The main focus is on the techniques used during process analysis. There are mentioned approaches that are used to easily and effectively assess process behavior using process behavior charts and how to deduce proper steps from the analysis results to improve the process. The last part of this thesis is dedicated to practical analysis of real process behavior data using implemented solution. The results show common usability of statistical methods and approaches to process analysis.

Quality assessment of pneumatic linear drives
Pecl, Tomáš ; Jankových, Róbert (referee) ; Budík, Tomáš (advisor)
This Master’s thesis deals with the evaluation of quality pneumatic linear drives. The theoretical part describes the problems in the field of pneumatic cylinders and statistical methods to perform the analysis. The practical part includes the execution and evaluation of the statistical analysis of the measurement process and pneumatic cylinders, also brings recommendations to optimize the measurement process. The methods used included analysis Gage R & R, Analysis control charts and data analysis using the process capability. The study was made for the purpose of improving test equipment Norgren Ltd. Used computer programs was Minitab Statistical Software and MS Excel.

Statistical Process Control
Hudečková, Eva ; Fiala, Alois (referee) ; Koška, Petr (advisor)
The master´s thesis deals with the problem of statistical process control. The theoretical part describes the basic quality tools and new quality tools, as a tool for collecting, recording, classifying, and analyzing data. The knowledge gained from the theoretical part are used to describe processes in the company Heat Transfer Systems s.r.o., analyze sticking points, control plans updating and to statistical process control in the organization.

Implementing of SPC into production process
Letáček, Jiří ; Koška, Petr (referee) ; Fiala, Alois (advisor)
This graduation thesis is concerned with implementing the SPC (Statistical process control) to the process plan. The aim of this thesis is an analysis of present status of manufacture laths bending and a selection of useful methods, which is possible to apply in a company processes. The main reason for SPC implementation is continual improvement of quality in manufacturing concern. The theoretical part of thesis consist of bending description, control of process quality, quality control instruments and errors in measurement. In practical part is described an actual status of manufacture and a solution of query.
