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.

Assessment of the operator reliability of the selected machine
Jakl, Tomáš ; Rozehnalová, Jana (referee) ; Kotek, Luboš (advisor)
The master thesis is focused on the reliability of the human factor in the operation of the production machine. In the first part the basic legislative requirements for safety and reliability of work are presented. In the second part, the reliability of the human factor is discussed along with a description of selected methods for assessing the reliability of the human factor. The research section then concludes with a proposed methodology for human factors assessment for the manufacturing process. In the practical part, the proposed methodology is applied to the selected process, which includes risk identification and outputs from the selected methods. The thesis then concludes by recommending preventive measures to eliminate the identified risks.

Assessment of production machine ergonomics
Klapetek, Václav ; Kotek, Luboš (referee) ; Rozehnalová, Jana (advisor)
The Master’s thesis addresses the issue of ergonomics. The aim of the diploma thesis is to analyze the current ergonomic state of the production line with the subsequent detection of ergonomic risks, the use of various assessment methods and comparison with legislative requirements. After defining the deficiencies, corrective actions are proposed, leading to their elimination and reduction of work intensity. The ergonomic analysis was performed within Tyco Electronics Czech s.r.o. The analytical part follows up on, in depth, the theoretical part of the work, where all its aspects are listed in addition to the introduction of ergonomics as a scientific discipline.

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.
