Dynamics of agile project management methodology Scrumban
Grohoľ, Robert ; Mildeová, Stanislava (advisor) ; Král, Miroslav (referee)
This thesis researches dynamics in projects managed by Scrumban. It describes the creation of system dynamics simulation model, which provides insight into the relationships between system components. It also presents data, that are further analysed with the purpose of discovering patterns in behaviour of project attributes in time, such as size of the product backlog, work in progress etc. The patterns are discovered and recommended parameter settings are provided so that there is no idle time or higher defect rate than necessary. Soft factors are also included in the model, namely the development team and the customer, which have a grand effect to the model behaviour. Managment flight simulator is developed, which provides the option to experiment even to users, who are not familiar with system dynamics modelling. The thesis consists of two parts. In the first part, necessary theory of project management, system dynamics and their fusion is provided. The second part is dedicated to the process of creating the simulation model, dynamic hypothesis formulation, mathematical modelling, testing and data analysis. In consideration of the analysis results, recommended policies are provided. Last pages of the thesis describe the user interface of management flight simulator and it's controls.

Český filmový trh a digitální filmové pirátství: Ekonomická analýza a navržené politiky
Janák, Pavel ; Voráček, Jan (advisor) ; Haindl, Michal (referee) ; Jánský, Jaroslav (referee) ; Choochote, Kitimaporn (referee)
The Czech theatrical market faces a major digital piracy problem. The availability of illegitimate digital distribution channels represents a challenge for managers, especially when original movies are uploaded to the Internet before or during their theatrical release. The crucial managerial task is to solve the problems of losses caused by piracy, and to find a balance between antipiracy investment and the maximal benefits it brings. Therefore, to maximize stakeholder utility, management decision-making needs to be complemented and supported. Firstly, the research investigates the basis of digital piracy, discusses the effects it causes, focuses on relevant stakeholders. The thesis deals with knowledge management and system dynamics using its principles and approaches and proposes a model supporting strategic management decision-making. The created knowledge-based computational model simulates the market's development of the Czech theatrical industry related to digital film piracy in the following scenarios: current market settings, industry-based administration, government-based administration and a mixture of the last two; the results of the different scenarios are discussed, evaluated and compared. The findings indicate that with the current settings in the Czech theatrical industry, the losses caused by digital piracy keep increasing linearly. Industry-based administration implies that the losses level off with a negligible yearly increase and the government-based solution reduces the losses more than the industrial administration. Nevertheless, the results show minor differences in total box office revenues, while differences in antipiracy costs are vast. Therefore, the predictive experiment based on the current market environment represents the most efficient version of the experiments. Even though losses are, the highest, real box office revenues are only a little different. Simply put, a moderate increase in box office revenues paid for by massive investments into antipiracy seems inefficient.

Applying System Dynamics and Agent-based Modelling in Archaeological Simulation
Olševičová, K. ; Danielisová, Alžběta
We apply the social simulation to the cultural milieu of the late Iron Age in Central Europe and its economic strategies, especially on the subsistence and the carrying capacity of the settlement agglomeration in relation to the daily economic needs of its inhabitants. By means of the computational models of the economics of the particular central settlement (Staré Hradisko oppidum) and its hinterland we aim to verify hypotheses about the economic sustainability in case self-supplying is applied. To achieve this, the agent-based modelling, cellular automata approach and system dynamics modelling are used. In the paper we present four alternative scenarios of population dynamics (baseline and three versions of depopulation) and four alternative scenarios of food production and agricultural practices (baseline and three types of external events). The set of models for all scenarios was implemented in NetLogo and Stella. Outputs of the models are subject of interests of archaeologists and according to their feedback the models will be refined and extended.

Model of Carrying Capacity - System Dynamics in NetLogo and Stella
Olševičová, K. ; Cimler, R. ; Tomášková, H. ; Danielisová, Alžběta
We compare implementations of system dynamics of Celtic settlement using two tools - NetLogo and Stella. The objective of the model is to catch the relations among the population growth, the production growth and the land use with respect to agricultural strategies. Our main objective is to better understand the Celtic society and economy and its sudden collapse. More broadly we are interested in the applicability of multi-method simulation (agent-based approach enhanced with system dynamics and process modelling) in archaeological research.

System model for analysis of applicant decision in project of CzechEkoSystem
Polák, Petr ; Mildeová, Stanislava (advisor) ; Král, Miroslav (referee)
System Dynamics is a powerful approach to understanding the behaviour of complex systems. This thesis is focused on a simulation model, that goes from principles of System Dynamics and the model will solve the problem of insufficient number of applicants that meet a specific set of project requirements, which are defined by the government agency, CzechInvest. The project, CzechEkoSystem, is mainly focused on efficient development of small and medium sized enterprises based on their pioneering business model. The thesis begins by describing the basic theories of System Dynamics that are introduced and elaborated on, within the particular tools of the simulation model problem statement. Then key terms about the CzechEkoSystem project are introduced. In the conclusion, results and recommendations for increasing the portfolio of pioneering small and medium sized enterprises are presented.

DSS for energy saving of potential clients
Škrobánková, Jana ; Mildeová, Stanislava (advisor) ; Kašparová, Dana (referee)
This diploma thesis focuses on a model-oriented system for decision support. The main contribution of the thesis consists in creating a system simulating energy saving which would result from the purchase of plastic windows and/or of a heat pump. The basis of the simulator is a functional model consisting of individual variables and connections between them and created in compliance with relevant notation. The thesis describes and illustrates not only the model structure itself, but, in the same time, also its logic on which basis the corresponding energetic saving is calculated after entry of necessary initial values. The diploma thesis includes, in addition to the model, also the description and the graphical representation of the created user interface which provides the user with easy entry of parameters and clear display of results. The introductory part of this work introduces the basic theoretical terms and approaches concerning the system dynamics together with its principles. The following part is dedicated to the description of the enterprise for which the system for decision support was created. The final part contains the above mentioned model, its structure and description, as well as the created user interface.

Application of system dynamics in the management of medical facilities
Kastner, Pavel ; Mildeová, Stanislava (advisor) ; Palivoda, Michal (referee)
At the present time, characterised by increasing complexity of not just socio-economics systems, decision-making in positions of executive management is becoming increasingly difficult. Although more and more attention is dedicated to use of information and communication technologies in corporate sector and organizations collect unprecedented amount of very detailed data from all areas, their real nature is often not considered. Data, information and knowledge, through which we can achieve real understanding of causes of the observed systems behaviour, are necessary basis for ability for prediction of tomorrow's effects of today's decisions. This thesis aims to highlight the essence of data, information and knowledge in organization and the necessity of systemic perception for creating efficient and effective decisions. The second part of this thesis presents design of system-dynamic model (including user interface), which explains the mechanisms of health care volume accounting in medical facilities with more departments. The model should facilitate understanding of functioning of hospitals by the public, and respect of general nature of medical facilities functioning to create a base for robust model-oriented decision support system for the management.

Solar energy market in Czech Republic - system dynamics approach
SMETANA, Martin
The main objective of this diploma thesis is to provide a paradigmatic view on the solar energy market within the environment of system dynamics. To reach this goal, it was necessary to create a dynamic model which will be sufficiently informative and reliable for generating the main behaviour patterns of the solar energy market. This model provides a macroscopic view on the problematic of solar energy market and therefore includes all its key components. Thesis further includes simulations of hypothetical scenarios aimed both on historical and future market development.

Pension reform in the Czech Republic - approach of system dynamics
PAPEŽ, Vladimír
The main aim of this diploma thesis is to provide a paradigmatic view on the future development of the pension system in Czech Republic within the environment of the system dynamics. This objective incorporates the goal of creating a dynamic model that will sufficiently informative and includes the key aspects, both the current and the future form of the pension system (PS) in Czech Republic. The results of the current form of PS conclude that under the presumption of slightly unfavourable demographic development and constancy of PS is the system unsustainable. The model also points out the fact that the problem of PS could be solved through its partial adjustment. Under the assumption of gradually increasing pension tax rate, opposed with the real value of pension benefit and gradual pension age postponement up to 71 years. The results of the pension form post reformed analysis pension form are based on the assumption of intergenerational schism. That means different attitudes to the pension system reform. Pension system post reformed analysis results coincidently work with the fact that all people under 30 years (year 2009) will join the voluntary pension fund system. The current scenarios consider that the coming generation of working population will without exception enter this voluntary system. The older population (aged over 31 years) will not participate in the pension reform. Another common feature of the proposed scenarios is the fact that all individuals will join the capital pillar (the pension voluntary system) at the beginning of the year 2013. When comparing current and post reform form of the pension system a remarkable finding has arisen. The model of the post reform PS shows considerably worse results than is model of the current PS form.

Specifika informačního managemntu v síťové topologii
Buzek, Jiří ; Mildeová, Stanislava (advisor) ; Král, Miroslav (referee)
This work deals with programs designed to manage data networks and to their use in managerial practice. The purpose is to explain how these programs contribute to a systemic understanding of managed network and system thinking. All these methods are applied on example of two largest wireless ISP companies in South Bohemia. The dissertation explains the issue of making mental models of the managed network, which concerns specially managers of ISP companies. The work is not an administrator view at programs for network management, but rather a management view and instructions how to use these programs in management decisions to solve complex problems and future development of managed network.
