IS/ICT sourcing strategies in healthcare facilities
Potančok, Martin ; Voříšek, Jiří (advisor) ; Pour, Jan (referee) ; Šalamon, Tomáš (referee) ; Vejvodová, Jiřina (referee)
The dissertation thesis focuses on information systems and communication technologies and ways they are provided (sourced) in healthcare. The aim of this dissertation thesis is to design and verify a model of IS/ICT sourcing strategy for healthcare as a factor leading to the improvement of patient care, taking into account different categories of healthcare facilities and other specifics resulting from the application in medicine. The introductory section of the thesis (Section A) defines the areas of health care and identifies their specifics. Moreover, categories of healthcare facilities are defined and therapeutic, nursing and IS/ICT processes are identified. Sourcing is defined for the needs of the designed sourcing strategy model and the current trends are analysed as well as the offered outsourcing services. In the next section of the thesis (Section B), requirements on the IS/ICT sourcing strategy model are defined. Theories of sourcing strategies are analysed including assessment of the current practices of healthcare facilities. Identification of specific factors affecting sourcing in healthcare is an essential part of this section. The most important section of the thesis is a design of the IS/ICT sourcing strategy model and its verification in practice at a real healthcare facility, which is described in the final part (Section C). The designed model employs two layers to cover the whole spectrum of healthcare facilities. The base layer defines the types of objects used in developing the sourcing strategy. The specific layer takes into consideration the differences between the various categories of healthcare facilities and provides the actual implementation. Successful implementation of the model including its two layers was achieved in an independent outpatient healthcare facility.

Level of Usage of Voice User Interface
Horáček, Jan ; Šalamon, Tomáš (advisor)
This study focuses on the voice user interface, that is the communication between a human and a machine using speech. The aim is to contribute to reader’s familiarity with basic theoretical approaches to the topic, to identify main software products and to assess their present level of usability. A recognition of crucial factors hindering mass utilization of such technologies by common users is included as well. The work consists of two parts. The goal of the first one is to introduce basic terms and principles of the functionality of the voice user interface and its three main parts: a system for speech synthesis, for speech recognition and a dialog manager. In the second part, characteristics of particular products based on the speech synthesis or recognition will be given, especially of those designed for general use on a PC. A chapter examining current situation and possible progress in the usage of the voice user interface by the visually impaired people follows. The last chapters study other possible utilities, where an adequate attention is paid especially to those bringing advantage to telephone users.

Modelling of decision-making networks
Šilar, Pavel ; Burian, Jan (advisor) ; Šalamon, Tomáš (referee)
Delegative democracy is a new concept of democratic governance. It is meant as a new system of trust among people. It is derived from principles of direct democracy and presents only minimal form of representation. The voter is not forced to cast his vote directly, but it can be transferred to a delegate. Delegative democracy is based on openness, awareness and trust. It is still only a concept and for real application it has to face rising critics. Main issues are high costs, threat of populism and corruption and overall complexity. Agent-based modelling is chosen to test the validity of delelagative democracy principles. It is suitable for studying social phenomena such as democratic governance. Agent-based models apply a "new kind" of artificial intelligence -- a dynamic system composed of individual and autonomous units -- agents -- which interact within the environment. Universal methodology called Agentology is used to propose a new agent-based model. This methodology is composed of subsequent steps. These steps cover initial analysis, conceptual and technological proposal and development of the model itself. Assessment of delegative democracy principles is achieved with data acquired from the agent-based model. Delegative democracy is less effective for small and cooperative system than direct democracy. If more voters are delegating, this effectiveness decreases even more. This conclusion is based on initial parameters of the model. Delegating voters count is indeed a relevant parameter whereas total voters count is not. The model has its basic predicative value and is open to further elaboration.

Least squares method using genetic algorithm
Holec, Matúš ; Tichý, Vladimír (advisor) ; Šalamon, Tomáš (referee)
This thesis describes the design and implementation of genetic algorithm for approximation of non-linear mathematical functions using the least squares method. One objective of this work is to theoretically describe the basics of genetic algorithms. The second objective is to create a program that would be potentially used to approximate empirically measured data by the scientific institutions. Besides the theoretical description of the given subject, the text part of the work mainly deals with the design of the genetic algorithm and the whole application solving the given problem. Specific part of the assignment is that the developed application has to support approximation of points by various mathematical non-linear functions in several different intervals, and then it has to insure, that resulting functions are continuous throughout all the intervals. Described functionality is not offered by any available software.

Multiagent simulation - State interventions into rental housing market
Janovský, Lukáš ; Šalamon, Tomáš (advisor) ; Hradecká, Petra (referee)
The thesis focuses on the use of multiagent systems to model the rental housing market. At first the aim was to create the simulation, which would bring a new perspective on the development of the entire market. For this purpose I selected a relatively young methodology titled Agentology, which was subjected to the criticism of a model after finishing the model. That was a secondary principal objective of this thesis. The work is divided into two parts. In the first theoretical part the rental housing market is described and there are discussed the most important factors affecting its state. Simultaneously the chapter describes the most significant State interventions into the market, as we know them from the official housing policies. In the next stage the reader is made familiar with the basic principles of multi-agent modeling. In this chapter there is also an overview of selected methodologies of multiagent systems and one of them is selected and applied in further phases of this work. The second part refers to the multi-agent model. Using the Agentology methodology market model is assembled. The methodology accompanies all stages of model development from the task formulation, through conceptual and technological level to the final evaluation. This work strictly adheres to the methodology and all its recommendations. In the end, the result represents a model whose functionality has been verified by analyzing the output data. Finally the thesis deals with criticism of the Agentology methodology. This criticism is a result of experience gained from previous development. It concerns evaluation of concrete steps and also of methodology as a whole in terms of admittance, integrity and practicality.

Vývoj agentních modelů pro ekonomickou simulaci
Šalamon, Tomáš ; Řepa, Václav (advisor) ; Hřebejk, Petr (referee) ; Král, Jaroslav (referee)
This thesis is about the development of agent-based models that are a method of simulation of economic processes and environments using multi-agent systems. Agent-based modeling seems to be an unappreciated approach that is expected and has a potential for a much wider application than it actually has. The purpose of thiswork is to evaluate the reasons for such situation and to offer solutions. The following were identified among the reasons for a low utilization of the method: a wide gap between theory and practice in the field, doubtful reliability of the method, lowconfidence in its results, complexity, missing methodologies, problems with suitable development frameworks, limitations of computational performance, a lack of awareness among the public and certain other problems. Agentology; (i.e. a methodology for the development of agent-based models) was proposed in this thesis in order to address issues regarding the development of agent-based models. There are six defined roles of project participants in the methodology: expert, analyst, modeler, platform specialist, programmer and tester. The design and development process consists of four phases and nine steps beginning with task formulation, conceptual modeling, and platformspecific modeling to the development of the system. For the design phases, agent modeling language for agent-based models was derived.

Modeling business and information system goals
Kovářová, Renáta ; Panuška, Martin (advisor) ; Šalamon, Tomáš (referee)
The bachalor thesis is about modeling business and information system goals. The objective of this modeling is to determine what are the long-term business and information system goals; it models goals in a current state (business or information system) "as-is" and goals in a future state "to-be". Goal modeling is not about modeling goals in a transformation between these states, because they are not long-lasting. This modeling belongs to an analysis of the system requirements technique. Because it is relatively young, while very beneficial method of system requirements analysis, it is necessary to give it a proper attention. Important is the very definition of the "goal" itself and the reason why we actually model and why. For goal modeling several modeling languages are, used, which include framework i* and KAOS methodics. This thesis closely examines both these languages, and compair their readiness for the goal modeling in a practical way.

Entropic Degeneration of Democracy
Bernat, Lukáš ; Pavlík, Ján (advisor) ; Šalamon, Tomáš (referee)
Democracy is always included in the discourse ?ver the theme of freedom and it is almost always considered an integral part of social order. In this context, it is a balance between freedom and power. Such discourses, however, view democracy as a political ideal and the real applications often run into democratic influences and social barriers of degenerative nature. These barriers leave nothing but the torso under the formal guise of democratic principles. This thesis unravels the influences and barriers that interfere with the application of the ideal of democracy. In this context, the technological development with which the dynamics of both social and political order changes, cannot be ignored. Based on the pieces of information about what kind of threat the degenerative effects of democracy represent, the thesis searches for such attributes, on the basis of which it is possible to construct a model of the entropic degeneration of democracy.

Application of agents in business process modelling
Miloš, Martin ; Řepa, Václav (advisor) ; Šalamon, Tomáš (referee)
This diploma thesis deals with the usage of agents in business process modelling. The aim is to identify possible uses in the problem area and to evaluate their potential. Intended usage is analysed on the basis of the objectives of process modelling. Described in detail, it focuses on potential application of agents in a process modelling itself, in deploying executable and flexible processes, process improvements and finally in dynamic planning. A further objective is to provide an overview of current research and literature in problem area. To fulfil the goal available literature is analysed and basis approaches are demonstrated in case study. Paper does not address the implementation of multi-agent systems (MAS). Following introduction reader is guided though basic elements of the processes and their modelling, concept of agents and modelling of MAS. As a process modelling notation BPMN in planned 2.0 release was selected. Next section is devoted to the usage of agents. The last part of the work is a case study discussing the possibilities of agents application in company operating public car auctions. In addition the process model (BPMN) transformation to agent model is presented and further developed as a interconnection between process modelling and agent-based systems. Combination of agent approach with business rules and hybrid simulation are proposed as the most promising usages.
