This work should mainly offer the summary of the real problems and risks arising from implementation similar systems and it also might be some kind of aid for other projects in the company as it reveals the risks and offers the instructions how to avoid risky situations.

In today's world there are many different substitutes for most products and services, increasing the demands on decision-making among substitutes. In order to make a decision, it may be very helpful to use multi-criterial methods for evaluating of the options, which are available to the general public through special programs. Thank to these programs, the general public does not have to be informed in detail about multi-criterial methods and can use the convenience of multi-criteria analysis. The aim of this thesis is to describe and compare the publicly available noncommercial czech software that allows the simplification of choice when choosing from several options according to specified criteria. The thesis work is focused on discrete models of evaluation that are simpler and more suitable for pre-defined alternatives. Non-commercial programs, many of which were created at universities, are evaluated in this thesis. Furthermore, some very well-known evaluation methods, which appear in some programs, are presented.

This thesis describes the implementation methods for multi-criteria evaluation into the software application. IZAR is a software product that solves decision problems. IZAR solves single and multi-criteria, continuous and discrete decision problems. This thesis describes the extension of application IZAR. Several methods of multi-criteria evaluation were added into application. Supplemented methods were chosen so that the extended applications use the most basic methods from the decision theory. Introductory part of the thesis describes the basic methods that have been implemented into IZAR. There is summarized the theoretical basis of each method. The central part deals with the description of each method in terms of implementation. Attention is paid to the parts of the algorithms that have been modified or extended so that the methods are universal. Finally, the thesis shows the test examples in which functionality of methods was verified. There is described a group of complicated decision problems and control conditions that were created for these problems to find the right results.

The master thesis deals with managerial decision-making, more specifically with the multi-criteria evaluation of alternatives under risk for the GAMACZ.CZ company, which currently solves problem of low profitability. The aim of the thesis is to define the decision-making objective(s), determine the set of evaluation criteria, identify potentially successful alternatives, determine their impacts and finally evaluate alternatives and recommend the most suitable one for the company. For the purpose of the multi-criteria evaluation with risk integration the author uses the Weighted Sum Approach. On the basis of these methods the most suitable option together with suggestions of implementation are proposed to the company and the reality check is executed.

Based on the obtained results the possible solutions which should be helpful for improvement of company´s processes even in case that the order is completed in time will be proposed.

Titanium alloys are strong candidates for the aerospace industry and biomaterial applications because of their low density, high strength-to-weight ratio and very high strength even at temperatures up to 600°C. Like many other engineering alloys, titanium alloys are prone to strong preferred crystallographic orientation development during thermomechanical processing. Part of the titanium processing route is to heat treat the material above the β transus for the purpose of homogenization and associated phase transformation. This heat treatment dramatically affected the microstructure and texture evolution. Theoretically, such heat treatment should result in a nearly random texture if all variants during α→β→α phase transformation are active. In reality, significant textures are observed after such a heat treatment process. The present project aims at developing a detailed understanding of the root cause for this relatively strong texture by means of EBSD and in-situ neutron diffraction studies. The effect of β grain growth on variant selection during β to α phase transformation has been investigated by using two variants of Ti-6Al-4V with and without 0.4 wt% yttrium addition. The aim of adding yttrium was to control β grain growth above the β transus by pinning grain boundaries with yttria. Both materials were first thermomechanically processed to generate a similar starting microstructures and crystallographic textures. Subsequently, both materials were solution heat treated above the β transus followed by slow cooling to promote growth of the α lath structure from grain boundary α. Detailed EBSD and in situ neutron diffraction analysis were carried out to study microstructure and texture evolution. The variant selection calculation suggests that more variant selection occurred in convectional material with a large grain size compared to material with yttrium addition. In situ measurements showed that β texture strengthened significantly above the β transus with increasing β grain size. There was no significant variant selection during α→β transformation; variant selection noticeably increased during β→α transformation with increasing β grain size. Additional interrupted cooling experiments followed by EBSD analysis showed early nucleation of α variants with a 'butterfly morphology' from β grain boundaries that have a pair of β grain with a common <110> pole. These observations suggest reduced nucleation energies for α formation in such circumstances allowing extensive growth of these α variants into unoccupied β grains making it a dominant variant. The influence of rolling temperatures (i.e. at 800 ºC and 950 ºC) to produce different starting texture, on texture evolution and variant selection during α→β→α transformation was also investigated. Laboratory X-ray, EBSD and in-situ neutron diffraction texture analyses were carried out. Even though the transformation texture is stronger at 800 ºC, the degree of variant selection is stronger in materials rolled at950 ºC compared to material rolled at 800 ºC. Here, the enhanced variant selectionfor the material rolled at 950 ºC was related to the different β texture. It is suggested that the combination of a particular β texture components promote variant nucleation that can increase the likelihood of having β grain pairs with a common <110> pole.
