Quality assurance in series production
Pecl, Matěj ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The bachelor thesis deals with the issue of quality assurance in series production. The main objective of the thesis is to research suitable quality control tools and application of selected tools to actual production. The thesis describes the selected series production and the quality requirements for such a production. Furthermore, the quality indicators monitored in the company where the selected production is located are described. A research of quality tools and a classification of the tools used in the company in terms of their use was conducted. Finally, the paper concludes with analyses of real data from the production, which were conducted using Pareto diagram and histogram The main cause of internal scrap, which is the screwing process, has been identified from these analyses. Corrective actions and monitoring of the situation were recommended. As the screwing process is unstable on other production lines, it was decided to change the product and process design.

The problem of cyber security in the EU industrial environment
Zauana, Magdalena ; Kovář, Jiří (referee) ; Maradová, Karla (advisor)
Práce představí důkladnou analýzu současných strategií kybernetické bezpečnosti přijatých agenturou ENISA, která je zodpovědná za zvyšování kybernetické bezpečnosti v EU. Analýza dále identifikuje nedostatky v implementaci přijatých strategií a osvětlí perspektivní možnosti optimalizace účinnosti agentury ENISA při zvyšování kybernetické bezpečnosti. Současně bude také zkoumat účinnost právních předpisů EU, evropských a mezinárodních norem, jejichž cílem je poskytnout cenný rámec pro organizace, které chtějí zlepšit svou kybernetickou bezpečnost. Kromě toho dokument navrhne opatření pro prevenci a obnovu kybernetické kriminality, která zvýší informovanost všech jednotlivců a organizací vystavených digitálnímu světu, aby se lépe chránili před kybernetickými útoky. To bude tvořit součást celkové analýzy IT rizik, která v konečném důsledku posílí technologická bezpečnostní opatření prostřednictvím metody FMEA. Nakonec bude proveden experiment, při němž bude počítač záměrně infikován malwarem nebo ransomwarem, přičemž budou popsána důkladná preventivní a detekční opatření k předcházení útokům a bude také navržen plán obnovy po útoku. Závěrem je konstatováno, že řešení problému kybernetické bezpečnosti v průmyslovém prostředí EU vyžaduje komplexní a koordinovaný přístup, který zahrnuje spolupráci všech zúčastněných stran. Na podporu argumentů použitých v této studii jsou zahrnuty i poznatky předchozích výzkumníků.

Quality assurance in engineering production
Novák, Adam ; Maradová, Karla (referee) ; Blecha, Petr (advisor)
The subject of this bachelor thesis is quality assurance in engineering production. The aim of the thesis is to reduce the number of non-conforming pieces of actuator production by applying quality management tools and determining recommendations for solving the problem. The research part describes the system, basic concepts and basic tools of quality management. In the practical part, the cooperating company, the actuator production process and the production quality indicators are presented. Then, the application of the tools to the data obtained from the production for one month is carried out.

Quality control analysis of fuel tanks
Kostková, Diana ; Maradová, Karla (referee) ; Zuth, Daniel (advisor)
In my bachelor's thesis, I focused on quality control, where understanding the entire issue and the essence of individual tests required examining the production process. Each type of production has its strengths and weaknesses, so I aimed to highlight these factors throughout my work. Subsequently, I delved into individual tests, deliberately selecting them so that each test evaluated a different parameter. This was followed by recommendations for improvement in practice, focusing on dimensional control to enhance production efficiency while minimizing time consumption. The main aim of this recommendation was to reduce scrap rates by at least one-third. I assessed the suitability of equipment using a multi-criteria evaluation method, ultimately identifying the most suitable equipment based on designated criteria, including measurement speed, measurement accuracy, price, safety and many others.

Proposal for a methodology to evaluate the capability of a hydraulic test stand
Sechra, David ; Blecha, Petr (referee) ; Maradová, Karla (advisor)
The diploma thesis specifically focuses on the application of capability analyses in the field of industrial hydraulics. The aim is to evaluate the capability of a hydraulic test stand for radial piston hydraulic motors. The thesis includes a theoretical analysis of the current state of the art, a systematic analysis of relevant elements affecting capability, and practical statistical data processing. The result is not only an evaluation of the test stand's capability but also the creation of a methodology for future capability analyses within the company.

Preparation of the certification of the quality management system of the university - department of foundry engineering
Slinčák, Andrej ; Potanko, Andrej (referee) ; Maradová, Karla (advisor)
This paper examines the issue of the quality management system according to the requirements of the standard ČSN EN ISO 9001:2016. The object of application is the Faculty Foundry of Brno University of Technology. The first part of the thesis consists of theoretical research. The said part presents the historical development of quality management and current approaches to the quality management. This is followed by an analysis of the ISO 9001 standard where the individual requirements are defined and explained, so that they can be applied in the practical part. I have also added results from studies on the motives and consequences of implementing a quality management system according to the ISO concept. The practical part focuses on the analysis of the current state of quality management in the faculty foundry and the preparation of the standard requirements, so that later the foundry can obtain the quality management system certificate.

Design of the process of input control of deliveries in the company
Ondřejová, Kateřina ; Sámelová, Vendula (referee) ; Maradová, Karla (advisor)
The thesis analyzes the current state of the process of incoming inspection in the company. It describes the current state of the process in the company and subsequent processes that are part of the whole organization. The thesis uses the PDCA methodology to define the weak points in the measurement system, which are parts of entry control. Furthermore, it will explain how tools and their applications are used to improve the measurement system the follow-up of the incoming inspection. Ultimately I would like to avoid an increase in low quality parts in the incoming inspection process. By implementing the defined methodologies, the data can be considered eligible and can be subsequently presented throughout the whole process.

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.
