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.

Statistics Control of Process Described by Attributive and Continues Variable
Svobodová, Hana ; Popela, Pavel (referee) ; Bednář, Josef (advisor)
This thesis aimes at approaching the problem of control diagrams. The first part summarizes the theoretical knowledge about the control diagrams, including their sorting based on the type of the monitored quantity. The different types of diagrams are described in detail. The second part deals with the practical use of control diagrams using actual data. Tests of definable causes are used on these data, and the causes of failure are sought. The key is to assess process stability.

Optimization of production process
Nováková, Veronika ; Krásová, Anna (referee) ; Fiala, Alois (advisor)
The aims of this dissertation are to analyze the current state of process control, to identify the product range in selected organization and to design the process planning methodology to ensure an optimal implementation. Optimization is understood as costs minimization while keeping an acceptable continuity of supply. The dissertation contains a description of technological and non-manufacturing processes of brick products, as well as the summary and description of the basic tools of quality management.

Statistical properties of control charts and capability models
Vidová, Katarína ; Jankových, Róbert (referee) ; Bednář, Josef (advisor)
The diploma thesis is focused on process stability and capability assessment. It describes certain types of control charts, basic capability indices as well as Box-Cox transformation. The practical part of the study is concerned with applying control charts on generated data and consequently on real data. By this, it focuses on comparing various methods of estimating sample standard deviation and on the impact of non-compliance with the assumption of normal distribution of process variable on process stability and capability assessment.

The proposal for the optimisation of control activities for a selected process
Kocmánek, Ladislav ; Jankových, Róbert (referee) ; Maradová, Karla (advisor)
The diploma thesis deals with the optimalization of control activities in the selected powder coating process. In today´s companies face increasing customer demands that demand high quality and speed of production. At Hitachi Energy is the powder coating process one of the most important processes, after which is introduced the final inspection of all painted parts. Due to situation on the labor market, the company cannot longer recruit new employees, but it must reduce the time and costs associated with powder coating inspection. The thesis focuses on the entire process of powder coating, identifies the most common poor quality in the process and determines the root causes of this poor quality. Based on these causes, solutions were designed and implemented with the aim of optimizing the control activity and reducing the costs of the poor quality of the powder coating process.
