Dizertační práce se zabývá návrhem integrované metody hodnocení bezpečnosti a spolehlivosti palubních leteckých systém za použití teorie grafů a fuzzy logiky. Navržená integrovaná metoda je univerzálně použitelná v oblasti hodnocení bezpečnosti a spolehlivosti, nicméně je primárně navržená pro použití v oblasti General Aviation a civilních bezpilotních prostředků. Současná podoba hodnocení spolehlivosti je téměř výhradně závislá na úsudku analytika. Použití komerčních softwarových nástrojů pro hodnocení spolehlivosti je extrémně nákladné, přičemž možnost přístupu a úpravy použitých algoritmů je minimální. Současný prudký vývoj palubních letecký systému je spojen s jejich zvyšující se komplexností a sofistikovaností. Integrovaná metoda používá teorii grafů, jako nástroj modelování funkčních závislostí mez jednotily prvky systému. Použití teorie grafu současně umožňuje daný systém analyzovat, hodnotit hustotu vzájemné funkční vazebnosti, identifikovat důsledky případných poruchových stavů. Aplikace fuzzy logiky umožňuje manipulovat s expertní znalostí a stanovit kritičnost daného prvku a systému. Kritičnost prvku zohledňuje pravděpodobnost jeho selhání, možnost detekce dané poruchy, závažnost těchto selhání vzhledem k vlivu na alokované funkce.

The master’s thesis deals with the use of fuzzy logic for evaluating the quality of suppliers of IT goods and other material for a selected company. The fuzzy model should facilitate decisions when selecting individual suppliers who should deliver goods for the implementation of IT projects. The model created in Microsoft Excel and MathWorks MATLAB should be helpful to the company's management and sales representatives.

This master thesis deals with detection of microsleep on the basis of the changes in power spectrum of EEG signal. The results of time-frequency analysis are input values for the classifikation. Proposed classification method uses fuzzy logic. Four classifiers were designed, which are based on a fuzzy inference systems, that are differ in rule base. The results of fuzzy clustering are used for the design of rule premises membership functions. The two classifiers microsleep detection use only alpha band of the EEG signal’s spectrogram then allows the detection of the relaxation state of a person. Unlike to first and second classifiers, the third classifier is supplemented with rules for the delta band, which makes it possible to distinguish the 3 states: vigilance, relaxation and somnolence. The fourth classifier inference system includes the rules for the whole spectrum band. The method was implemented by computer. The program with a graphical user interface was created.

This Diploma thesis analysis the supply environment of VKV HORÁK s.r.o. according to the requirements of the quality management ISO 9001:2001 regarding the suppliers rating. The thesis also analyses the present way of suppliers rating and brings new, more sofisticated model of rating using the fuzzy logic. The new method should succesfully solve the questions of suppliers rating and should be suitable for the firm according to the resources needed for its application.

This work deals with the tools of financial market. It is demonstrated to a reader, what is the financial market composed from, how it actually works and what are the characteristics of securities, why the securities are used, what are the advantages and disadvantages. We are going to focus on field of mutual funds, as a part of collective investment. Thanks to investment questionary is made a research to find out which strategy is prefered by citizens. We are going to suggest the optimal financial portfolio to this strategy by the program GRANT. We are going to use the fuzzy logic characteristic and we are going to show to the investor how can he choose the suitable invesment tools to his portfolio according to his requierements.
