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.

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.

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.

Usage of Statistical Methods to Assure Capability of Production Process
Kuthanová, Dominika ; Baranová, Zuzana (referee) ; Doubravský, Karel (advisor)
The aim of bachelor´s the thesis is to evaluate the quality of production using tools of statistical process control and to propose possible measures leading to its improvement. The thesis uses the following statistical tools: control charts, normality tests and capability indexes. The bachelor´s thesis also clarifies the principle of Six Sigma methodology. The output of the thesis is the proposed application of following tools: target control carts and the Cpm index for statistical process control of the researched company.

Determination of capability and stability of a chosen technical process
Šváchová, Mariana ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
This diploma thesis deals with the evaluation of the capability of a specific production process. The theoretical part of the work contains a description of statistical process control, types of control charts and evaluation of process capability. The practical part is focused on evaluating the capability of a specific process. The method of dataset collection is described at first, then this data are analyzed and the capability of this process is evaluated.

Detection of key factors of non-standard pieces in series production
Beňo, Tomáš ; Blecha, Petr (referee) ; Bednář, Josef (advisor)
The presented thesis deals with the issue of statistical quality control of a specific production process. The thesis presents a range of statistical tools that can be used to identify the factors causing a high proportion of non-standard pieces. The diploma thesis practically introduces the application of these quality management tools to the production process characterized by an increased proportion of non-standard pieces, in which the factors causing their occurrence are unknown, and as following the thesis in detail introduces the approach how to detect these factors. The last part of the work summarizes the recommendations handed over to the company in order to verify the conclusions of the thesis.
