Presented diploma thesis is focused on evaluation of the supplier’s risk and the selection of the most suitable supplier with the use of artificial intelligence. The main part of the diploma thesis deals with the creation of the decision models. The decision models will be created in MS Excel and MATLAB based on the rules of the fuzzy logic. These models will determine the most suitable supplier for the company expert Elektro GOLA s.r.o. and they will also evaluate the supplier’s risk.

Tento projekt se podrobně zaměřuje na data z avioniky a může být chápán jako horní vrstva nad systémy monitorujícími poruchy, která poskytuje dodatečné informace o letu. Pro konkrétní návrh byly vybrány Airbus A320 a A340 jako zástupci moderních a rozšířených dopravních letadel. Vyvíjená aplikace analyzuje dvě vybrané komplexní situace z toku dat palubní avioniky a hledá podmínky, které vedou k abnormálnímu chování letadla (nikoliv poruchám). Práce je primárně zaměřena na letové fáze, strukturu dat (a jejich kategorizaci) a na vývoj aplikace na bázi fuzzy systému s expertní znalostí uloženou v jeho pravidlech.

This diploma thesis deals with cryptography. It describes its basic allocation and problems of number theory that needs to be addressed. It also deals with methods used to review the formal security of cryptographic protocols from a mathematical point of view. It analyse the tools used to automatic and semi-automatic evaluation of the safety of cryptographic protocols. It describes the process of working with these tools and finally test the security of protocols Kerberos, EKE and Unilateral authentication using symmetric cryptography, HMAC function and hash function. These tests are in tools AVISPA, ProVerif and Scyther. At the end is comparison of results.

The thesis includes the selection of suitable flat for the clients of reality group M&M reality holding a.s. on the base of defined criteria and their importance at using the fuzzy logic. The target of this thesis is the contribution of a functional, understandable and transparent model for the evaluation of the real estate’s offers with the use of fuzzy sets.

This diploma work deals with an opinion on recent state of administration in VEEM TRADING s.r.o. and choice of a new information system with an idea how to automatize administration. The choice was realized on specific fixed company criteria according to a mathematic model based on fuzzy logic. There is also an evaluation of information system by HOS 8 method in the diploma work.

The master’s thesis “Utilization of expert systems in marketing research” deals with the development of an application based on an expert system, knowledge basis of which contains expert information from the area of CCTV security systems design. In this thesis, the used expert system is described and also its connection to the relevant marketing research is mentioned.The solution of the expert system is carried out in C++ language programming and the purpose of the program is to eliminate misunderstandings and inaccuracies which occur during the initial negotiations between the salesmen and potential investors.The created software product, based on the knowledge basis of the experts in the field and past experience with camera systems, helps the customers decide what type of system, in what range and with what configuration is suitable for them. Hereby the orientation customers is encouraged in the way as described by the modern concept of marketing.

Master’s thesis deals with application of modern methods for analysis and decision-making for optimal supplier selection. There is specifically used a theory of fuzzy logic in the thesis. The goal of the thesis is creation of instrument, which can help a company with choosing the best building work supplier for prefabbed building reconstruction. This study will be used in practice.
