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.

The Application of Fuzzy Logic for Rating of Suppliers for the Firm
Baierová, Lucie ; Doskočil, Radek (referee) ; Dostál, Petr (advisor)
This Master's thesis deals with design of models for rating of M. K. R. plus suppliers of steel wires using fuzzy logic. The decision-making models are created in the MS Excel and in the MATLAB software. This thesis includes acknowledgement with theory, which will be used in the practical part for design of individual models. Current and potential suppliers of the company will be evaluated using the created models and their benefit to company will be assessed.

Integrated development environment for Artificial Intelligence Fuzzy Numbers Module
Pergl, Miroslav ; Hrabec, Jakub (referee) ; Jirsík, Václav (advisor)
Master’s thesis deals with mathematical operation with fuzzy numbers. The first part of the thesis deals with theoretical knowledge of fuzzy arithmetic and defines fuzzy sets, fuzzy numbers, universum and five membership function used in program. In the concrete it describes – cut method for dealing with fuzzy numbers as with limited interval for specific level which simplifies computation. The second part of the thesis contains description of programmed module for mathematical operation with fuzzy numbers. There is described creation of user interface which is using to set parameters of computation. There are also described support functions which make operation with fuzzy numbers possible and operation ensures output.

Fuzzy Preference Structures in Multicriterial Decision Making
Majer, Tomáš ; Stryka, Lukáš (referee) ; Hliněná, Dana (advisor)
V mnohých rozhodovacích problémech evaluujeme akce z různých pohledů, které nazýváme kritéria. Například při ohodnocovaní auta uvažujeme kritéria jako maximální rychlost, cena, zrychlení a spotřeba. V obecnosti při rozhodování s ohledem na různá kritéria se setkáváme s problémem preferencí. Jedním z nejjednodušších řešení je vážený průměr uvažovaných kritérií. V této práci aplikujeme výsledky řešení jednoho multiriteriálního problému, přičemž porovnávání kritérií realizujeme použitím fuzzy preferenčních struktur. Naše řešení je ilustrováno na praktickém příkladě.

Diagnostics of the state of the machine/machine components with the help of fuzzy sets
Horák, Roman ; Zuth, Daniel (referee) ; Marada, Tomáš (advisor)
Diploma thesis deals with the use of fuzzy logic in the field of technical diagnostics. The thesis is divided into theoretical and practical parts. The theoretical part describes technical diagnostics, fuzzy logic and genetic algorithm. The theoretical part is followed by a practical part in which fuzzy logic is tested on the Iris dataset and then the acquired knowledge is applied to a technical dataset evaluating machine fault conditions. At the end of the chapters of both datasets, the results are summarized and evaluated. The last chapter of the practical part is devoted to the description of the developed scripts in software Matlab 2022b. Part of the work are attachments in which the created FIS models and written scripts are stored.

Fuzzy and interval-probabilistic methods of risk assessment of the investment project implemented by public private partnership
Ostrouško, Viktorie ; Synek, Miloslav (advisor) ; Ivánek, Jiří (referee) ; Scholleová, Hana (referee)
The result of my dissertation justifies the use of fuzzy-sets theory to make a prediction of cost risk of a PPP project, when there is not enough information available to clearly describe the project, and, when the probability distributions of the variables that characterize the project are unknown. I showed that fuzzy-sets theory and linguistic variables may be effectively used in such a case. In this thesis were classified different types of uncertainty and investigated traditional methods for estimating efficiency of a investment project in conditions of uncertainty. On the basis of the analysis were offered new ways of conducting risk analysis for PPP projects with use of fuzzy sets theory. The main goal was to create an application model for risk assessment of the PPP project which, with a high degree of reliability, suggests a general assessment of situation. The goal set in my work was met. Model of risk assessment of the project proposed by me gives more stable results in comparison with the probabilistic model. For comparison were used different types of probability distribution functions and membership functions. The following conclusions and statements describe the novelty of the work on fuzzy logic and economic theory: develops a method of cash-flow (future expenditure connected with the appearance of risk) modeling of investment project in fuzzy environment, demonstrates the use of fuzzy sets theory in projects analyses and describes how to calculate and interpret this value, demonstrates example of the use of results applied to the analysis of infrastructure development project in Moscow, Russia. The possibility of using this method is not only in the analysis of infrastructure development projects, but also in realization of non-commercial projects by social institutes and government agencies.
