Model simulation using SIMIT
Váňa, Dominik ; Pásek, Jan (referee) ; Arm, Jakub (advisor)
This bachelor's thesis is focused on simulating a technological proces. The teorethical part of the text deals with the simulation tools available on the market. Special attention is paid to SIMIT tool, which is a complex solution for simulating processes. The thesis describes the basic control and the procedure of creation in this tool. The theoretical analysis presents the possibilities of its extension with additional libraries. It contains a brief description about these libraries, which provide much more simulation options. SIMIT is a virtual commissioning tool, a process design approach that is used to simulate a virtual factory model, test it, and debug it before it is deployed. This is a cost-effective and timesaving approach. In the practical part of the thesis two simulators were created with the SIMT tool, each of which simulates an excercise from the subject „Programmable logigs controllers“ (BPGA). The thesis presents model schemes of simulated processes that replace the real physical model. The results of the work are the created simulators, descriptions of their operation and valuation of their features and the properties of the SIMT program itself.

Setting the parameters of the mathematical model of the Engine ECU
Vychopeň, David ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis is focused on creating a suitable methodology for determining the parameters of the electronic control unit of the engine. Discusses how the measurement of input data into the methodology, the basic description of its functions and display the resulting values. It includes evaluation of applicability of the methodologies and the real parameters when compared with the parameters established on the basis of established methodology.

Numerical Model of Engine Control Unit
Křepelka, Jan ; Beran, Martin (referee) ; Svída, David (advisor)
Master’s thesis deals with issues of controlling the amount of fuel injected by the control unit. Model of four-cylinder engine and computational model of control unit were constructed in the simulation software Lotus Engine Simulation. Then was made model checking of the control unit by simulation two transients (acceleration and shifting). In conclusion was made application a created model on the New European Driving Cycle (NEDC) and appropriately evaluated and processed the results of this simulation.

Transition State Simulation of Combustion Engine
Forbelský, Antonín ; Beran, Martin (referee) ; Svída, David (advisor)
Master's thesis focuses on the simulation engine transients. The model of single-cylinder engine was constructed in simulation software Lotus Engine Simulation. Then was made simulation of transients. The thesis try to describe the influence of moment of inertia of the engine, the engine starting speed and process of throttle opening during the transients. For all modes also compare two methods of fuel control.

Analysis and optimization of the production system using computer simulation
Vaďura, Pavel ; Knoflíček, Radek (referee) ; Simeonovová, Ivana (advisor)
This bachelor thesis focuses on the process of the creation of a simulation model followed by dissimulation of this model, and finally optimalization of the system using the results of the simulation. The aim is to clarify basic terms about production with consequential usage of simulation models and their application in the production proces. Next, the creation of the simulation model in the simulation software Factor/AIM is explained and illustratively demonstrated. The first part of the bachelor thesis deals with theoretical information about the production proces, division and creation of the simulation model and it analysis this model with the purpose of finding narrow places and suggesting its optimalization. This simulation proces is simplified version of the manufacture of seamless pipes.

Thermo-physical parameters of exo-sleeves and their application in simulation programmes
Zajíček, Roman ; Kuzma, Zbyněk (referee) ; Roučka, Jaromír (advisor)
Thesis discusses exothermic sleeves. The first chapter briefly described the defects can occur during solidification. Further, there are provided methods for removing these defects. The method is described in detail using risers with an emphasis on the exothermic sleeves and thermo-physical parameters characterizing these sleeves. It also describes the influence of these parameters on the accuracy of computer simulations. In the final part of the work is done measuring of the real casting, which is then simulated in the Quikcast.

The usage of numerical code FLASH in plasma astrophysics
BROŽ, Jaroslav
My diploma thesis is focused on the use of numerical computer codes for simulation in plasma astrophysics. They will learn the basic characteristics of the Sun, a closer focus on the solar corona and the solar corona heating problem. The following section is devoted to simulation software in plasma astrophysics, their installing and displaying the results using the visualization software. In the conclusion is demonstrated using this software on a model example and a simulation that performs simulation of impulsively generated waves in solar coronal loops.

Comparison of Simulation Software and Areas of Its Application
Hora, Pavel ; Kuncová, Martina (advisor) ; Dlouhý, Martin (referee)
This diploma thesis deals with computer simulation. In the opening, there are descriptions of theoretical aspect of computer simulation, simulation model structure and individual phases of simulation process. After that follow areas of application, characteristic features of each area and classification of simulation models, that are used in those areas. In this thesis only 4 areas of application were chosen: automotive industry, logistics and transportation systems, healthcare and military simulation. Each application area contains descriptions of a few chosen simulation software products that are used in this area. At the close there is a price comparison of described simulation products, their usage in Czech Republic and their development evaluation.

Comparison of simulation programs and their application
Krupa, Martin ; Kuncová, Martina (advisor) ; Řezanková, Hana (referee)
Abstract (eng): This diploma paper compares available software for simulations. These are MATLAB, WITNESS, SIMUL8, SIMPROCESS and CRYSTAL BALL. In the first part, the dynamic simulations are explained, its methodic, purpose, areas of implementation and after that it describes the simulation of Monte Carlo type. These are the basic types of simulations used by programs mentioned in this paper. After a short introduction follows detailed description of the system requirements, user interface and the principles of working with these programs, that contains also a definition of basic function blocks. This paper also describes another important information like price, available licenses and in the attachment the pictures of the programs interface. The next part of my paper is based on analyze of observed articles, which concern this special area of interest. I try to describe the usage of this software on a market, area of application or eventually a type of simulation. The information from data assimilation are ordered in transparent tables and visualized on a graphs and diagrams. At the end is the final summary, which I believe will be beneficiary for the readers.
