Master ’s thesis deals with evaluation of investment using advanced methods of analysis and modeling with regards to the best offer. The content of the thesis consists of creating two decision making systems based on fuzzy logic. The thesis also contains a theoretical basics which are necessary for the creation of both systems and evaluating the benefits of the solution.

This thesis deals with the use of basic means of artificial intelligence, respectively fuzzy logic to evaluate the benefits of company's potential suppliers. There are mainly used principles of fuzzy logic in MATLAB, expert systems and analysis in MS Excel respectively. VBA development environment.

This diploma thesis deals with the evaluation of security companies for ZETOR TRACTORS a.s. using fuzzy logic models. The main part of the thesis consists of proposals for the evaluation of the suppliers' evaluation of the company. Decision models are created in Microsoft Excel and Matlab. Another part of the thesis deals with analysis and comparison of results from both programs.

The diploma thesis deals with evaluation of fertilizer suppliers using fuzzy logic models. The main part of the thesis consists of proposals for the evaluation of the company's suppliers. Decision models are created in Microsoft Excel and Matlab. Another part of the thesis deals with analysis and comparison of results from both programs.

Correct behavior of programs can be defined by their temporal properties. One of the options for formal specification of such properties is  linear temporal logic - LTL . This master's thesis describes design and implementation of a tool for automatic checking of temporal properties of programs, that are specified using Past-Time LTL formulae. The trace of a given program is analyzed in run-time and any violation of given formulae is reported in details to help to find the code location with a root cause of the bug.

This Thesis analyses various representation models in the matter of Latvian tractor market penetration by Zetor brand products and herewith presents all necessary information concerning this problem. All suggested representation models are going to be evaluated and the output of this evaluation is the optimal model presentation for Zetor Group management. This authority is responsible for strategic decision of final representation model for Zetor brand products on Latvian tractor market.

The content of this diploma thesis is to create a simulation model of the logistics chain of the production area of an industrial plant in order to design the logic control of material flow. Plant Simulation software from the company Siemens PLM Software is used to create the simulation model. The diploma thesis consists of system analysis of the researched area of the production plant. With the help of the simulation model, simulation experiments and evaluation of the obtained results are made. According to the results, the conclusions are drawn.

The diploma thesis deals with the application of the theory of fuzzy logic in the evaluation of client translation commissions for a foreign language text. This fuzzy model is used for better selection of orders and faster allocation of human resources for specific orders. The fuzzy model is composed of multi-valued decision-making criteria that are essential for the company. The model is processed in MS Excel using VBA and MathWorks MATLAB.

This diploma thesis deals with the evaluation of supplier risk for a chosen company Vinařství Soška using the fuzzy logic principles. This company like many others is forced to shift its sales to the Internet environment due to the government restrictions established to reflect the pandemic situation. For a successful Internet business, it is necessary to choose an optimal ecommerce software based on the company requirements. For this purpose, two fuzzy logic models are built in Microsoft Excel and MATLAB software. Their aim is to evaluate the potential risk of all of the suppliers. Based on this evaluation, the results are transformed into specific recommendations on how to choose the optimal solution for the company. The first chapters deal with the general theory that is later used in the analytical part.

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.
