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.

Using simulation to predict defects in and cast Al-alloy castings
Šolc, Petr ; Bařinová, Dagmar (referee) ; Čech, Jaroslav (advisor)
The aim of this work is comparing three casting process simulation programs for porosity and microstructure prediction capabilities for die-casting. After confronting these results with experimentally measured data taken from real castings it could be said that simulation is pretty accurate for DAS microstructure prediction and hot-spot areas. Amount of measured porosity could not be compared with predicted values because specimens were not taken from the exact hot-spot areas.

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.

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.
