Quality assurance of pneumatic cylinders
Pabiška, Martin ; Maradová, Karla (referee) ; Jankových, Róbert (advisor)
This Master thesis deals with the requirements for the quality of ISO standard compliant pneumatic cylinders, which are machined and assembled by a local manufacturer. According to the philosophy of continuous improvement, this thesis describes the project to decrease the number of air leaks detected by automatic testing machines. The main benefits of the thesis are the improvement of the design of pneumatic cylinders and the improvement of their assembly procedure leading to a reduction in the number of air leaks from pneumatic cylinders on automatic test equipment. It also provides an overview and general procedure for selecting, analyzing, implementing measures and taking further opportunities to improve the quality management system of pneumatic cylinders in the company.

Reliability assessment of a hydraulic switchboard production proces
Machová, Lenka ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The Diploma thesis is focused on possibilities of an assessment of a hydraulic switchboard and its manufacturing process. Furthermore, it analyses methods individually which are suitable for quality assurance and production reliability, which are described in details. The follow-up work focuses more on the Statistical Process Control (SPC) method which is applicable in the early warning system and the Failure mode, effects, and criticality analysis (FMECA) method, applicable in the planning system. These two methods are further applied to the newly introduced process of machining the hydraulic switchboard as an effective tool not only for assessing the reliability of production, but also for its subsequent securing and maintaining in a relevant condition.

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.

Early Warning System for recording outages from the assembly line
Makovičková, Lucie ; Zuth, Daniel (referee) ; Maradová, Karla (advisor)
The bachelor's thesis on a topic “Early Warning System for recording outages from the assembly line“ aims to update assembly line outages, thanks to what the work gained a good motive to present the Early Warning System process in practice, in the company Bosch Diesel s.r.o. Jihlava, where this update of assembly line outages takes place. The work first introduces the high-pressure pumps and their assembly lines, which are the most connected to the system. Then the basic elements of the system are described, and the Power BI system is defined. The practical part explains way of collecting the necessary data for outages updating and how the Early Warning System gets the information about outage during the installation of a high-pressure pump on the assembly line to the higher responsible persons. Subsequently, thanks to the obtained statistical overview of all outages and to the performed visualizations in the Power BI system, the knowledge is evaluated.

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.

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.

Proposal to Improve Maintenance Strategy in the Industry 4.0 Context
Milčíková, Nikoleta ; Maradová, Karla (referee) ; Zuth, Daniel (advisor)
This bachelor's thesis deals with a proposal of a maintenance strategy refinement in the context of Industry 4.0 in a selected company, particularly in the operating center of Subtil corporation located in Myjava. The first part of the thesis deals with the theory of maintenance itself, its strategies and development across industrial revolutions and the related theory of the Industry 4.0 concept and its cyber-physical principles. The practical part is devoted to the description of the current maintenance strategy in the company and the description of the current state of knowledge in the field of maintenance in the context of Industry 4.0. Subsequently, the findings are applied to the maintenance strategy of Subtil according to its needs and capabilities.
