Abstract
Hlavním úkolem této bakalářské práce je identifikovat vágní posuzování a neurčitosti v metodách analýzy spolehlivosti. V úvodu práce je popsána základní terminologie zavedená ve spolehlivosti. Zvláště pak ve vztahu k posuzování a analýzám spolehlivosti technických systémů. Další kapitola je věnována životnímu cyklu výrobku, který se dělí do několika etap. Jsou zde uvedeny některé druhy metod analýz, které se v jednotlivých etapách životního cyklu využívají. Další kapitola se věnuje riziku ve vztahu k analýzám spolehlivosti a popisuje několik základních informací o riziku. Následně je vysvětlen pojem vágnost a proces metody analýzy. V další části práce dochází k identifikaci nepřesností v metodách analýz. Z velkého množství jsem si vybral metody FMEA, FTA. Závěr kapitoly jsem věnoval lidskému faktoru a bezporuchovosti lidské činnosti, což je velmi problematické téma. Výsledkem a cílem této práce je identifikace slabých míst metod analýz spolehlivosti a míst, ve, kterých dochází k nepřesnostem nebo by mohlo dojít ke špatnému rozhodnutí na základě předložených dat. Došlo k možným návrhům, jak odstranit tyto nepřesnosti nebo neurčitost dat. Tyto návrhy jsou popsány u každé z uvedených etap.
The main task of this bachelor thesis is to identify vague assessment and uncertainty in reliability analysis methods. The introduction of this work is dedicated to describing the basic terminology introduced in reliability. Especially in relation to the assessment and analysis of reliability in technical systems. Next chapter is devoted to the life cycle of a product which is divided into several stages. There are stated some of the types of analysis methods that are used in each stage of the life cycle. Next chapter is devoted to risk analysis in relation to reliability and describe some basic information about risk. The term vagueness and the process of analysis methods is then explained. The next part of the thesis deals with identification of inaccuracies in the methods of analysis. From a large number of methods. I chose FMEA and FTA. The conclusion of the charter was dedicated to the human factor and reliability of human activity, which is a very problematic issue. The result and the aim of this work is to identify the weak spots of methods of analysis of reliability and places, where there are inaccuracies or could lead to bad decisions on the basis of submitted data. Some possible proposals to remove these inaccuracies or uncertainties have been made data. These proposals are described in each of the listed stages.
