Design of an Internal Methodology for MSA of Attributive Data in the Company
Jaroš, David ; Maradová, Karla (referee) ; Sámelová, Vendula (advisor)
This diploma thesis deals with the design of an internal methodology for MSA of attributive data in the company following a finding in the IATF 16949:2016 audit. The thesis text aims to map the current trends in approaches to attributional MSA analysis with a focus on visual inspection. Based on the theoretical findings, a new company methodology is to be subsequently proposed. The defined aims of this thesis were fulfilled, resulting in a methodology that meets the company's requirements as well as the methods described in the relevant manuals. The proposed methodology uses the cross-tab method, which describes the analysis of attributional data without knowledge of the reference. The result of the analysis are kappa coefficients, which determine the measure of agreement in the evaluation, and efficiency values of the measurement system. By following the principles described in this thesis, it is possible to generalize the proposed methodology for use in other companies.

Reliability assessing of the fiber optic packaging process
Plodková, Zuzana ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The diploma thesis deals with the assessment of the reliability of processes at the packaging center in the company CommScope Czech Republic s.r.o. The first part of the work is research about options for quality management using ISO 9000 standards, but also TQM approaches. At the same time, methods and analytical techniques are discussed, which will be further used in the practical part of this thesis. The following section introduces CommScope Inc. and its main product - optical fiber. The practical part contains an introduction to the packaging center and its processes, it also describes the analysis of the reliability of the original state and proposals for corrective measures that were designed within the Kaizen event. The rest of the work is then devoted to the implementation of the proposed changes and their economic assessment. Finally, an evaluation of the methods used, the results achieved and other recommendations are given.

Quality Assurance Network
Ježek, Jiří ; Maradová, Karla (referee) ; Rozehnalová, Jana (advisor)
The bachelor thesis deals with increase of quality of manufacturing process using the QA network. This tool graphically maps the occurrence and detection of defects in manufacturing process so that the defect is detected as soon as possible after its occurrence. The method Failure mode and effects analysis (FMEA) was used as the source for preparation of Quality Assurance Network. In the thesis, there is an analysis of a current situation in branch of quality – improving process and failure mode and effects analysis. After that there is a realization of QA network and the evaluation of the solved issue in conclusion.

Proposal to change the categorisation of work at the selected workplace
Plánková, Barbora ; Rozehnalová, Jana (referee) ; Maradová, Karla (advisor)
The diploma thesis deals with work categorization falling into the issue of occupational health protection. The theoretical part is devoted to current legislative reguirements of the EU, the Czech Republic and relevant standards. It also provides a general overview of the system of public health authorities together with a more detailed description of the work categorization topic and related concepts and requirements. This thesis has been made in cooperation with Varroc Lighting Systems, s.r.o., Nový Jičín. The practical part deals with the suggested change of categorization of the optimized assembly line work positions for car rear lighting (B479 OUTER RL). The main aim of this work is to check the correctness of the classification of individual work positions. The intention of updating the categorization is also to reduce the negative impact of critical risk factors of working conditions, which brings benefits for both employees and employers. The specific course of the classification of individual risk factors with a focus on the noise as a critical risk factor is demonstrated on the riskiest work position of the assembly line. In the end, the achieved results of updated classification of all positions are evaluated. The follow-up changes and the resulting benefits of updating the categorization, including other practical recommendations, are also summarized.

Design of optimization of extrusion process control tests
Pavlíková, Michaela ; Šrámek, Jan (referee) ; Maradová, Karla (advisor)
The master´s thesis is focused on the optimization of extrusion process control tests. The practise was performed at Fraenkiche CZ s.r.o., which is a company specialising in plastic tubes and components. The aim of the master´s thesis is to analyse the current state of the specific issue, systematically analyse the topic, statistically analyse and discuss the results and propose a new method of extrusion process control tests with my recommendation for practise. The introduction forms a preview into the quality management, plastic materials and processing of them. The practical part contains an analysis of the company and their production process. This information was helpful to the design of a list of control tests. With the help of basic quality tools, I prepared a new design of a list of control tests. The basic statistical processing showed an evaluation of finance savings. In the final part I evaluated the results and proposed several recommendations for improving current processes in the company.

Costs of low kvality
Pavlíková, Michaela ; Maradová, Karla (referee) ; Rozehnalová, Jana (advisor)
The objective of this bachelor thesis is area of costs for non-conforming products in industrial company. The aim of the bachelor thesis is a system analysis of the current state of the specific issues and a proposal to create a system for monitoring the cost of low quality in manufacturing proces. Some preview into quality management is itemized in the introductory part. I also describe the management of nonconforming products, with which I was able to analyze the collected data and develop a solution in the final part. Next I did an analysis of the company FRAENKISCHE CZ s.r.o. and I did an analysis of cost of low quality in this company. The data obtained from the cost analysis I proceed with the help of quality tools and I was carried out their evaluation. In the final part I evaluated the results and proposed several recommendations for improving current processes in the company.

Reliability issues in the development and production of control systems
Králíčková, Dominika ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The master thesis deals with the reliability issues in the development and production of control systems. First, the company UNIS, a.s. is described with an emphasis on the Division of Aviation and Advanced Control. A list of ways of managing the organization, which deals mainly with the positive features of process management and the creation of process maps. The following is an analysis of business processes from the quality management system in the company UNIS, a.s., through the current overview of processes and controlled documentation to the basic processes of the Division of Aviation and Advanced Control. Then the development and production processes are analysed in detail. This is followed by a system analysis of the issues addressed, which describes, how is it appropriate to proceed with process management and why. There are also FMEA and FTA methods, which are further applied to determine the current state of processes in UNIS, as. The FMEA and FTA methods resulted in findings that are discussed in the next recommendation. Finally, the achieved results are evaluated.

Digitization of data for non-conforming pieces (NOK) in the company
Ježek, Jiří ; Zuth, Daniel (referee) ; Maradová, Karla (advisor)
The Masters thesis is focused on the digitalization of data for non-conforming pieces with NOK status made on assembly line. It is mainly about designing a solution that will help to eliminate the nowadays outdated analogue methods. For the choice of digitization, two methods of solution implementation will be proposed in the thesis along with the method of data reporting. These streamlining will consequently lead to not only time but also economic savings for the company. The thesis concludes with recommendations for further development and economic evaluation.
