Risk Analysis of a Weldment Production Process
Slámová, Aneta ; Kurucová, Šárka (referee) ; Blecha, Petr (advisor)
This diploma thesis is focused on the risk analysis of a selected production process of the company SIK METAL s.r.o. The work is divided into three parts, the theoretical part, then the analysis of the current state and the design part. The theoretical part defines the basic concepts that relate to risks. These theoretical findings are then applied in the second part of the work, where risk identification is performed using various types of analysis. Based on selected analyzes, proposals and recommendations are proposed in the final part of the diploma thesis. Proposals and recommendations contain financial quantifications.

Reliability assessment of the Safety Helmets Manufacturing Process
Kartali, Csaba ; Rozehnalová, Jana (referee) ; Blecha, Petr (advisor)
The theoretical part of this master thesis lists all the necessary prerequisites which are needed in order to carry out a full and comprehensive reliability assessment of any given process. To do so it provides an overview of reliability in general, mathematical and statistical guidance together with a more detailed picture of the application and description of the process by quantifiable indicators. Furthermore it gives an overview of two important analysis tools, such as FTA and FMEA, accompanied by the basic principle and summary of the Six Sigma methodology and tools. The practical part of the thesis deals with the detailed description, quantification and goals of the process of safety helmet manufacturing and testing in order to be able to carry out a suitable assessment of the reliability by using the necessary set of tools and methods in order to identify the failures and their causes in the process by addressing them with suitable means of changes and corrective actions.

Development and Implementation of Energy Savings and Energy Management Methodology in an Industrial Enterprise
Dudarev, Ivan ; Demeč, Peter (referee) ; Suchánek, Rostislav (referee) ; Blecha, Petr (advisor)
V současné době se problematika energetických úspor dostává do popředí zájmu jak na úrovni jednotlivých podniků, tak i na úrovni celého státu. Často bývá příčinou sporů ve vědeckých kruzích i mezi odborníky z praxe. Lidstvo tradičně začalo využívat energii z minerálních přírodních zdrojů, které však ve srovnání s obnovitelnými zdroji energie mají omezení. Výzkum a implementace moderních technologií jsou ztíženy otázkou investic a časově omezeny. Proto se evropská strategie energetické bezpečnosti zaměřuje na energetickou účinnost, která je jedním z nejefektivnějších způsobů zlepšení bezpečnosti spotřeby energie. Velké společnosti a podniky jsou jedním z hlavních spotřebitelů energie. Proto je tato vědecká práce zaměřena na problematiku úspor energie a zlepšování energetické účinnosti podniku. Těžiště práce spočívá ve vytvoření a zavedení metodiky pro úsporu energie a managementu hospodaření s energií ve výrobním procesu automobilového podniku. Dále je pro účely této práce vytvořen a popsán způsob vizualizace spotřeby energie v prostředí virtuální reality
