Utilization of artificial intelligence in vibrodiagnostics
Dočekalová, Petra ; Huzlík, Rostislav (referee) ; Zuth, Daniel (advisor)
The diploma thesis deals with machine learning, expert systems, fuzzy logic, genetic algorithms, neural networks and chaos theory, which fall into the category of artificial intelligence. The aim of this work is to describe and implement three different classification methods, according to which the data set will be processed. The GNU Octave software environment was chosen for the data application for licensing reasons. Further evaluate the success of data classification, including visualization. Three different classification methods are used for comparison, so that we can compare the processed data with each other.

The Application of Fuzzy Logic for Rating of Suppliers for the Firm
Olšová, Renata ; Doskočil, Radek (referee) ; Dostál, Petr (advisor)
Cílem této diplomové práce je návrh vhodné metody, jak vyhodnotit dodavatele modelů letadel a leteckého příslušenství holandské společnosti Aviation Megastore. Tato polečnost existuje na trhu již více než 25 let a má více než 170 dodavatelů po celém světě. Proto vznikla potřeba jednotlivé výrobce a distributory ohodnotit a zvážit jejich vývoj během jednotlivých let, případně u některých vybraných dodavatelů zvážit vzhledem k neuspokojivým výsledkům možnost ukončení spolupráce. Pro vyhodnocení bude použit program MS Excel a MATLAB.

Fuzzy Markov chains and their use in risk management
Šindelková, Petra ; Vymazal, Tomáš (referee) ; Misák, Petr (advisor)
This thesis deals with the application of Markov chains for the production of concrete products. The theoretical part is focused on clarifying the concepts of risk management and describes the procedures for dealing with classical Markov chains. There are presented basics of fuzzy logic and finally there is explained the procedure using fuzzy logic in calculating of classical Markov chains in the subsection entitled Fuzzy Markov chains. The practical part describes production process, namely concrete pavements. On this production process is applied knowledge from the theoretical part and there is a comparison and evaluation of two methods of Marcov chains calculation (classic and fuzzy approach).

Nonlinear Control of Complex Systems by Utilization of Evolutionary Approaches
Minář, Petr ; Ošmera, Pavel (referee) ; Oplatková,, Zuzana Komínková (referee) ; Matoušek, Radomil (advisor)
Control theory of complex systems by utilization of artificial intelligent algorithms is relatively new science field and it can be used in many areas of technical practise. Best known algorithms to solved similar tasks are genetic algorithm, differential evolution, HC12 Nelder-Mead method, fuzzy logic and grammatical evolution. Complex solution is presented at selected examples from mathematical nonlinear systems to examples of anthems design and stabilization of deterministic chaos. The goal of this thesis is present examples of implementation and utilization of artificial algorithms by multi-objective optimization. To achieve optimal results is used designed software solution by multi-platform application, which used Matlab and Java interfaces. The software solution integrate every algorithms of this thesis to complex solution and it extends possible application of those approaches to real systems and practical world.

The Use of Means of Artificial Intelligence for the Decision Making Support on Stock Market
Vaško, Jan ; Kříž, Jiří (referee) ; Dostál, Petr (advisor)
Diploma thesis deals with analyzing the possibility of using artificial intelligence, specifically artificial neural networks and fuzzy logic, on the capital markets as a tool to support decision making in business. The Matlab software is used for this purpose. The work is divided into three parts. The first part deals with theoretical knowledge, brief description of the current situationin is covered in a second part and the theoretical solutions are applied to the system in the third section.

Intelligent System for Generating and Analysis of Trading Recommendations on Financial Markets
Martinský, Ondrej ; Hrubý, Martin (referee) ; Zbořil, František (advisor)
This master thesis deals with the price prediction on financial markets. It describes automated trading systems based on technical analysis and discusses a soft computing approach to construction of such systems. Also, this thesis combines conventional trading strategies with the fuzzy logic. The practical part of this thesis contains also a framework for composing, simulation and analysis of the automated trading strategies. The simulator contained in this framework is implemented in the Java language and based on DEVS formalism. Because of this, there is a possibility to embed real-time components into the trading model. This work contains also a database of historical financial data and tools for their automatic actualization.

Supplier Risk Evaluation Using Fuzzy Logic
Novák, Lukáš ; Peštál, Ivan (referee) ; Dostál, Petr (advisor)
The diploma thesis deals with the evaluation of suppliers using fuzzy logic for a selected company. The created model will be used to make efficient and faster decisions about selecting the most suitable supplier for the given orders. Based on the criteria that are important for the selected company, a fuzzy model is created. The final evaluations of the most suitable suppliers are created in MS Excel and MATLAB.
