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.

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.

Evaluation of supplier risk
Czeczotková, Iveta ; Mayer, Jan (referee) ; Dostál, Petr (advisor)
This dissertation deals with the risks which are connected with selecting the suitable suppliers of computer components for the Weps s. r. o. company. The selection of the supplier is realized by the use of fuzzy logic. Theoretical bases are also described in this dissertation. Moreover, there is an analysis of the risks and a proposal for the solution to this problem in the Microsoft Excel and Matlab programmes. The result of the dissertation should provide an instrument for objective evaluation of the suppliers, which is the company in collaboration with.

Evaluation of Investment with the Usage of Fuzzy Logic
Vaňková, Jana ; Šebestová, Monika (referee) ; Dostál, Petr (advisor)
The thesis deals with the evaluation of investments in intangible fixed assets. The company VIKI, spol. s.r.o. is interested in a new storage space acquisition, and therefore the main objective is to choose the best offer by using fuzzy logic. Evaluation is done in Excel, particularly in the Visual Basic environment and in MATLAB. The output of the thesis is an easy to use form that can be reused for other possible offers.
