The growth of online activities in our daily lives has led to substantially increased attention on how organizations and their computer systems handle Personal Information (PI). Independently, the wide adoption of Web Service Architecture (WSA), for the integration of software, creates an opportunity to facilitate support for privacy by monitoring the use of PI by web services and enforcing applicable privacy policies. This thesis designs an agent for privacy monitoring and enforcement in a WSA environment and creates a prototype as a proof of concept. The agent is based on a specific multi-agent architecture for privacy compliance. The design of the agent has led to extension of the architecture to bring out its full potential in monitoring PI flows and enforcing privacy policies in a WSA environment. The evaluation of the prototype has led to suggestions on its implementation for an operational environment.

Enterprise Resource Planning systems are large source of information usable for management decision--making. However, these data are often kept in incomprehensible form for common user. Especially for support of management decision--making was developed set of processes and technologies called Business Intelligence. With its tools are created comprehensible analysis. On practical example there is shown that Business Intelligence tools can be easily used for generating entry data for multi--criterial evaluation of variants. Methods of multi--criterial evaluation of variants are applied to solve the problem of a company that is forced to close some of its stores due to financial loss.

Thesis on "The practical application of operations research methods in the preparation of contracts", deals with methods of using multi-criteria decision making in the choice of parts to assembly stations needed to process orders. Included is also the engagement plan. In the theoretical part we can find a description of the methods and basic concepts of project management. The practical part of business information on individual works. Then, the selection of two parts by the three selected methods. Finally, the cost and time analysis of the entire procurement process.

Cílem diplomové práce je použití různých metod vícekriteriálního rozhodování v realitě konkrétně zhodnocení postavení firmy SAMSUNG na českém trhu, jak si zde stojí v porovnání s ostatními konkurenčními společnostmi. Dalším cílem, bylo posloužit subjektům, kteří zamýšlí pořídit si tento druh spotřební elektroniky. Úkolem bylo uspořádat výrobky podle výsledků jednotlivých metod. Zaměřila jsem se hlavně na výrobky společnosti SAMSUNG. Při výběru elektroniky musíme vzít v potaz velké množství kritérií, a to jak kritéria ekonomická, jako je cena, tak také kritéria technická. K výpočtům jsem využila MS Excel a program SANNA.

The purpose of my thesis is use of various methods of multicriterial evaluation of alternatives in a reality, and particularly the estimation of positions of Volkswagen brand at the market of new cars in Czech Republic and which positions do they take in comparison with other carmakers. The following purpose was to help customers who are going to get to itself the car. The aim was to order cars in each of 10 classes on the basis of results of each method. For my analysis I use methods WSA, TOPSIS and ELECTRE III. For calculations I used MS Excel and program SANNA.

This master thesis deals with practical application of simulation models and multi criteria evaluation of different alternatives in the field of air transport. The aim of this thesis is to show, and demonstrate using a simulation as a possibility of improving arrival and departure capacity of the M.R Stefanik Airport in Bratislava. There is a selection of low cost airlines based on a customer opinion. These airlines could increase the number of offered flights from the airport. Descriptions of various simulations can be found in the theoretical part, same as WSA, TOPSIS and MAPPAC, subsequent demonstration of these methods is shown in the practical part. The thesis is based on the results of practical application of simulation models followed by the application of multi criteria evaluation of alternatives. Furthermore this thesis compares the final results of the arrangement of low cost airlines using different methods.

The aim of my thesis is focused on choosing best fitness center according to concrete offer in Prague. Using methods of multi-criteria decisions I will calculate the order according to important information. Specifically, I work with three methods, Electre III, WSA and Topsis. Theoretical description of these methods and their applications using the Sanna is included. The work is extended by survey - ten women were interviewed to find out how they stand with exercises. This survey was very useful mainly because of getting new weights and thus new order for all three methods. The last chapter is devoted to the case of improving studio "Dokonalé tělo" and its position. I communicated with its owner Ing. Jan Stehlík, he was very nice and willing and interested in improving.

Coronal mass ejections (CMEs) are some of the extraterrestrialevents most impactful to earth. Eorts to model and predict theireects have seen new possibilities in the two most recent decades dueto multiple new spacecrafts providing a wider range of data than everbefore. Models of these events suer from a number of inaccuracies,one of them being the density ratio between the CME and the ambientsolar wind. Since the arrival time for potentially harmful disturbancespredicted by models has been proved to be highly sensitive to thisparameter we therefore take care to set it as accurately as possible.Traditionally this value is either set to a default, justied by denitionand theory, or set to the density ratio between the bulk if the ejectedgas and the surrounding medium. A proposition has been made tomeasure density enhancement dierently, using a reference point at theshock wave preceding the CME for each event. This method strives toimprove arrival time predictions and was in this paper tested for onecoronal mass ejection event. Two runs if the model WSA-ENLIL+Conewas made; one with the default value of density enhancement, onewith a value determined through the revised method using coronographdata. Running the model with the revised value improved the predictedarrival time by moving it forwards in time by 4h, which was still tooearly. Other input data into the model run was then discussed as apossible cause of the remaining inaccuracy. / Koronamassutkastningar är ett av solfenomenen som påverkar jorden mest.Nya rymdfarkoster med instrument som satts i arbete de senaste två decenniernahar gett data som gjort det möjligt att modellera och förutse dessaevent till en högre precision än någonsin. Alla dessa modeller lider av någonform av felkälla, en av vilka är kvoten mellan densitet för massutkastningenoch den omgivande miljön. Eftersom förutsedda ankomsstider för potentielltskadliga störningar har visat sig vara särskilt känsliga för denna parameterså tar vi särskild hänsyn till att ange den så precist som möjligt. Vanligtvissätts detta värde till ett fast standardvärde, som anges av dess denitionoch bakomliggande teori, eller till kvoten mellan utkastningens bulk ochomgivningen. Ett förslag har dock lagts fram om att omdeniera parametern.Denna metod strävar efter att förbättra förutsedda ankomsttider ochhar i denna text testats för en koronamassutkastning. Två körningar avmodellen WSA-ENLIL+Cone gjordes; en med defaultvärdet för densitetsratiot,en med värdet satt genom mätning av empirisk cononagrafdata enligtden föreslagna metoden. Att köra modellen med den nya parametern förbättrade den förutsedda ankomsttiden genom att ytta den framåt i tidenmed 4 timmar, vilket fortfarande är för tidigt. Andra inputdata i modellendiskuterades då som möjliga orsaker till den återstående diskrepansen.

A case study which examines the agreement between prediction and data is performed for three, complex interplanetary shocks which were detected at the Sun-Earth Lagrange point L1 and induced moderate to intense geomagnetic storms. We use model output from previous runs of the coupled coronal-heliosphere WSA-Enlil+Cone model, available through the Community Coordinated Modeling Center (CCMC), and in-situ data from the OMNI data set. Code written in MATLAB is used to compare the model output with the in-situ measurements of the interplanetary magnetic field as well as the density, speed and temperature of the solar wind. In addition, the difference between the predicted and actual shock arrival time is computed and regions of potential temperature depression are identified. A considerable discrepancy is found between data and model for the studied events. The main reason is deemed to be an inadequate representation of the ambient solar wind as well as the complex interactions between interplanetary coronal mass ejections and corotating interaction regions. We suggest future steps to be taken for the further development of the model as well as for the general understanding of space weather and the Sun-Earth connection. / Denna fallstudie undersöker överensstämmelsen mellan modell och data för tre interplanetära chockvågor, som kunde detekteras vid jordens Lagrangepunkt 1, och som orsakade geomagnetiska stormar av måttlig till kraftig styrka. Vi använder oss av tidigare genomförda körningar av den sammansatta WSA-Enlil+Cone modellen, som avbildar fortplantningen av temporära störningar med ursprung i solens korona, såsom koronamassutkastningar, ut i heliosfären. Modellen gjordes tillgänglig av Community Coordinated Modeling Center (CCMC) och datan inhämtades från OMNI. Kod skriven i MATLAB nyttjades för att göra en jämförelse mellan modell och faktiska mätningar av det interplanetära magnetfältet samt solvindens hastighet, densitet och temperatur. Utöver detta, beräknas också skillnaden mellan förväntad och faktisk ankomsttid av respektive interplanetär chock, och tidsperioder med en temperatursänkning utöver det normala identifieras. Vi finner en omfattande avvikelse mellan modell och data, i synnerhet för de fall där på varandra följande koronamassutkastningar förväntas interagera eller rent av slås ihop samt för uppskattningen av den omgivande solvindens egenskaper och det interplanetära fältet under pågående geomagnetisk störning. Interaktionen mellan koronamassutkastningar och närliggande ko-roterande interaktionsregioner har ej heller återskapats väl av modellen ifråga. Slutligen ger vi förslag på möjliga, framtida åtgärder som kan bör tas i åtanke vid konstruerandet av framtida versioner av nämnda modell, liksom för den allmänna förståelsen för rymdvädrets inverkan på Jorden.

This diploma thesis deals with description of methods and original on-line application for solving multicriteria evaluation of alternatives problems. Methods based on maximisation of utility value (WSA), minimisation of distance from ideal alternative (TOPSIS), evaluation of preference relations (ELECTRE) and evaluation along preference flows (PROMETHEE) are described and implemented in the application.
