The proposal of the system of regular monitoring of the suppliers’ process capability indices
Kubica, Ondřej ; Zbudil, Ondřej (referee) ; Škapa, Stanislav (advisor)
This diploma thesis named “The Proposal of the System of Regular Monitoring of the Suppliers’ Process Capability Indices” is divided into two sections. There is a theory about statistical process control with emphasized process capability analysis in the first section. The content of the second section is starting point, procedure and the outcome of the project I worked on in Robert Bosch Company, České Budějovice. The aim of the project is the improvement of input quality via the evaluation of suppliers based on their outcomes of SPC.

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.

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.

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.

Statistical Analysis of Data from PDF Files
Oltmanová, Kristína ; Burgetová, Ivana (referee) ; Bartík, Vladimír (advisor)
This thesis is concerning the process of data extraction from tables from documents in PDF format and their subsequent analysis with the exploitation of statistical methods. The goal of this thesis is to demonstrate the process of obtaining, processing and analyzing data from PDF files, which, in consideration of their program processing, create a finite number of subgroups with common characteristics. Firstly, the reader will become acquainted with the fundamentals of PDF file processing and basic mathematical principles that are required in order to statistically evaluate given data. Obtained theoretical principles are then applied to practical use and programming form in the Python programming language. The resulting web application is programmed using the Flask Python library and is usable on a local server.

Problems in Solder Paste Stencil Printing for Fine Pitch Components
Šimeček, Ondřej ; Polsterová, Helena (referee) ; Starý, Jiří (advisor)
Despote the indisputable advantages of fine-pitch components, is need to calculate with a few trouble during production, especially increased requirements for accuracy of mounting and solder printing. In this work I’m concerned with problems of solder printing for these components and evaluation using SPC. For the evaluation I used 3D paste inspection based on laser scanning of the surface. The output of this work is to describe the principles of solder printing and elaborating of GR&R, SPC analysis and histograms of solder printing for some outputs. I focused in my master thesis on motive design change of problematic components and economic evaluation of the adjustments.

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.
