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.
