Master's thesis deals with design and development of two decision-making systems, which can be supportive during suppliers rating and selection the most suitable one from them. Both of the models, that one, which was made in the MS Excel, and also that one, which was made in the MATLAB, use principle of fuzzy logic and are designed according to the requirements of the selected company. Diploma thesis contains also all of theoretical bases, which are necessary for a design of both systems, and evaluation of benefits of the solution.

A method to adapt the Generalized Predictive Control parameters to improve broadband disturbance rejection was developed and tested. The effect of the parameters on disturbance rejection has previously been poorly understood and a trial and error method was used to achieve adequate results. This dissertation provides insight on the effect of the parameters, as well as an adaptive tuning method to adjust them. The study begins by showing the effect of the four GPC parameters, the control and prediction horizons, control weighting &lambda , and order, on the disturbance rejection and control effort of a vibrating plate. It is shown that the effect of increases in the control and prediction horizon becomes negligible after a certain point. This occurs at nearly the same point for a variety of &lambda 's and orders, and hence they can be eliminated from the tuning space. The control effort and closed-loop disturbance rejection are shown to be highly dependant on &lambda and order, thereby becoming the parameters that need to be tuned. The behavior is categorized into various groups and further investigated. The pole and zero locations of the closed-loop system are examined to reveal how GPC gains control and how it can fail for non-minimum phase plants. A set of fuzzy logic modules is developed to adapt &lambda with order fixed, and conversely to adapt order with &lambda fixed. The effectiveness of the method is demonstrated in both numerical simulations and laboratory experiments. / Ph. D.

A metodologia de avaliação da sensibilidade ponto-a-ponto é aplicada a conectivos fuzzy e conectivos fuzzy intuicionistas, considerando a ação de negações fortes e automorfismos. O objetivo principal neste trabalho consiste na avaliação da robustez de operadores de diferença, representáveis por composição de negações e agregações da LF e da A-IFL. O operador de diferença tem aplicação direta em conceitos da FL e da A-IFL, quando do uso de conceitos de distância, medidas de similaridade e entropia. O trabalho colabora com a investigação da robustez na construção dual da classe de operadores de diferença em LF e A-IFL, incluindo possíveis construções conjugadas obtidas por automorfismos representáveis. / This dissertation focuses mainly on fundamental concepts relating to the study of robustness, duality and in conjunction Fuzzy Logic (FL) and its intuitionistic extension proposed by Atanassov (A-IFL). The methodology for assessing the sensitivity point-to-point is applied to fuzzy connectives and fuzzy connective intuitionists considering the action of strong denials and automorphisms. The main objective of this study is to assess the robustness of di?erence operators, representable by composition of denials and aggregations of LF and A-IFL. The di?erence operator has direct application of the concepts and the FL-IFL, when using distance concepts of similarity and entropy measures. The research work cooperates with the robustness of the dual construction di?erence operator class LF and A-IFL, including possible constructions conjugate obtained by automorphisms representable.

This master thesis deals with the virtual gate position and liquid level control system. The main characteristics of automatic control systems, fuzzy logic systems, their properties and formation principles are reviewed. Conventional and advanced control methods are presented pointing out their benefits, drawbacks and problems to be solved. Physical modelling and simulation issues are also discussed. Physical, mathematical, simulation and animation models of the system are produced. Position and level controllers are designed. The simulation of gate position and liquid level control processes is performed. The simulation model is built up using MATLAB Simulink and Fuzzy Logic Toolbox. The simulation results prove that the proportional controller fits very well for controlling gate position. However, the results of liquid level control “upwards” using PI controller are only satisfactory. Unsatisfactory results are obtained using the same controller for liquid level control “downwards”. Substantially better results are achieved using fuzzy logic controller. The models produced can be useful for further investigations and learning purposes.

This report concerns the development of the game engine and game logic that are used within the game Steam Tale, which during the development process was known as Project Steam Age, by the group StormBound. The game was developed targeting mobile devices, and within this report is included a short perspective on the history of mobile gaming. The game’s genre, JRPG, short for Japanese Role Playing Game, and peripheral concepts in regards to it are explained as well, and in relation to other genres and games available.   The game was made for Android v2.3 and later and as such coded in Java. Amongst the difficulties encountered, as detailed within this report, were the task of ensuring that the game runs on a wide range of phone hardware, including aspects such as both with and without hardware-based graphical acceleration, varying amounts of storage space and CPU-cores, as well as differing screen sizes. Furthermore, at the creation of applications such as this one should consider resource handling, especially concerning graphics and sounds, a topic discussed in this report. / Denna rapport behandlar utvecklingen av den spelmotor samt spellogik som används i spelet Steam Tale utvecklat under projektnamnet Project Steam Age av gruppen StormBound. Spelet utvecklades i första hand för mobila enheter, och i rapporten ingår även en kort undersökning av mobila spel i ett historiskt perspektiv. Även spelets genre, JRPG, en förkortning av Japanese Role Playing Game, kommer att förklaras som hastigast med referenser till andra spel inom genren.   Spelet programmerades för Android OS version 2.3 och framåt i språket Java. En av svårigheterna som påträffades, såsom beskrivs i rapporten, var att säkerställa att spelet fungerar för den varierande prestanda som mobila enheter utgör, inklusive aspekter såsom med eller utan hårdvaruacceleration av grafik, varierande mängd lagringsutrymme och processorkärnor samt storlek på skärmar. Därtill bör man vid skapandet av en applikation av denna typ beakta resurshantering, framförallt beträffande grafik och ljud, ett ämne som behandlas i denna rapport.
