Computer simulation model concept of an automated sorting system
Dvořák, Patrik ; Kašpárek, Jaroslav (referee) ; Urbánek, Michal (advisor)
In response to the growing demand for fast sorting of items, this bachelor thesis focuses on automated sorting systems. It describes the whole system in detail, from the basic principle, to the partitioning, the technologies and sensors used, to the advantages and diverse applications. It includes current trends for small volume shipments in this area. The thesis presents the concept and layout used to create the simulation model in Tecnomatix Plant Simulation software from Siemens. A matrix of experiments was created for the simulation model. Subsequently, simulation experiments were performed to find an optimization solution. Finally, verification and validation was performed where the simulation model was compared with the analytical calculation result.

Creating a simulation model of multi-reservoir system in the HEC-ResSim
Keilová, Nikola ; Marton, Daniel (referee) ; Menšík, Pavel (advisor)
Bachelor´s thesis is focused on the description of the programming of the device HEC-ResSim and the subsequent creation of the simulation model water system the Vír I and Brno. To create a simulation model using real data on the reservoirs. A simulation model is compiled for the management of the storage function and the calculation is carried out with a daily step. To simulate the flow of water to the system reservoir is used the real flow series. Part of the work is a translation of a clear manual to the program HEC-ResSim

Analysis of selected effects on water management solution storage function of reservoir system
Čechová, Martina ; Daniel,, Marton (referee) ; Menšík, Pavel (advisor)
The bachelor thesis deals with the influence of the effect of water loss by evaporation in the water management solution storage function of reservoir system. To determine the size of the effect of water loss by evaporation is used simulation model. The simulation model is created with SOMVS. Determining the size of water losses from reservoirs is made simplified method. Loss of water by evaporation is solved for selected level hydrologic reliability of evaporation. To find the optimal size of the storage volume of the proposed reservoir are used all optimization methods included in the SOMVS, that is the grid method, Monte Carlo method, the modified gradient method and differential evolution.

Problematic of Fast Automatic Tool Change by Working Machinery
Pavlík, Jan ; Marek, Jiří (referee) ; Velíšek,, Karol (referee) ; Demeč, Peter (referee) ; Kolíbal, Zdeněk (advisor)
This dissertation thesis is focused on the problem of the Automatic Tool Change for milling centers, which is recently shown as a very current topic. The content of this work is to conduct a comprehensive research of various types of ATC depending on the type of machine, as well as research of the current tool interface relating closely with these problems. There was made a comprehensive analysis on the basis of data obtained by comprehensive research, from which both the main factors affecting this topic and the area dealed and developed by this work resulted. The most problematic area of machinery used nowdays for the Atomatic Tool Change was detected as manipulator provided the exchange between spindle and tool storage. Kinematic structure and design of individual elements affects very significantly the dynamics of the whole process of exchange of tools. Therefore, the work is focused on problematic of the manipulator. The main results of this thesis are constructional design of several types of manipulators, which were partly realized within the project 1.2.4 of Brno department of RCMT in the form of the testing stands. There was developed simulation models for selected types of manipulators which were verificated by measuring on the real stand. On the basis of abovementioned problem there was identified another key issue related not only to the exchange process but also with complex problem of service life of spindle. It is a grab force in the process of picking tools. The work outlines the possibilities for further research of these forces on the service file of spindle (especially on service life of bering groups of spindle).

Modelling of the Gear Pump Manufacturing
Horák, Michal ; Rožňák, Ing Martin (referee) ; Videcká, Zdeňka (advisor)
The diploma thesis deals with the analysis and optimization of production lines of the gear pump components. Specifically, it is pre-production, ie a production line for machining gears and production line for machining of bodies. These two components are then assembled on the assembly line. The creation of a simulation model in the Tecnomatix Plant Simulation program, which corresponds to the real state of production lines, is used for optimization. The simulation model is then used to perform the proposed experiments in order to optimize production lines and select the ideal solution with respect to the selected objectives.

Design of a Robotic Cell for Flat Parts Production
Závodský, Martin ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
This master’s thesis deals with the design of a robotic cell for the automation of woodworking machine tending. The task of the robot is to manipulate with the specified laminated chipboards of various sizes, before and after machining. The boards are brought to the cell on pallets in three possible placement variants. After a brief research part, conceptual designs of cell layout were created. The optimal and further elaborated design came as a result of selected evaluation criteria. The next part of the thesis consists of designs and selection processes of individual components. These were later used to create a simulation model in Tecnomatix Process Simulate software (Siemens), that helped to verify the functionality of the cell layout, design the control logic and acquire the time of the manipulation cycle used for informative calculation of annual production. In the end, the final design was evaluated from an economic point of view with an emphasis on the return of the initial investment.
