Optimalization of thermoelectric linear actuator
Tlach, Michal ; Páleníček, Jan (referee) ; Vlach, Radek (advisor)
This dissertation describes the process of designing, process of optimalization and the following implementation of the changes of the thermoelectric linear actuator which operates the opening and the closing of the valves used in the most modern buildings for example for floor heating. It is a product produced in large series with the annual production of more than half of a million items. The reason for the optimalization is the instability during the assembly in the production and the reduction of costs, whereas the final assembly takes place in Germany. The dissertation deals with designing of the conceptions for solving of the trouble parts of the current version of the actuator. The chosen concept is consequently optimalized, tested and put into production.

Algorithms for advance production planning and scheduling
Kršák, Pavol ; Kaczmarczyk, Václav (referee) ; Pásek, Jan (advisor)
Bachelor‘s thesis analyzes solution of operational problems of production planning. Pur- pose of the thesis is presentation of operational problems of production planning and following proposal and implementation of planning algorithms in language C# on specific planning problem. By the presentation of the problematic is listed company „COMPAS automatizace s.r.o.”, which enabled implementation of the project. The thesis analyzes planning methods and process of their implementation. More specifically the thesis ana- lyzes evolutionary algorithms, expert systems in planning and deterministic planning via linear programming. In third chapter is described in more details planning program of production of coffee blends, which was provided by COMPAS company. Like a next, the thesis describes specifically proposal of solving based on evolutionary principle. The solving consists of the model of technology designed to production of coffee blends and ActionList. ActionList represents a set of rules that are governed by model. Then ru- les are defined undergone an evolutionary process in an effort to find better solution the existing. Applied features implemented in the system COMES to repurpose by the imple- mentation of module COMES Modeller are developed together with detailed description in the fourth chapter.

Management During the Contract by the Company
Možnár, Matej ; Flamík, Lukáš (referee) ; Jurová, Marie (advisor)
This thesis deals with the process of contract management in the company Duo Form Ltd. and it's conceptual departments as well as it's manufacturing process. The aim of this work is to analyze the current situation and to propose a better way of contract management. The proposal consists of two parts. The first part deals with contract processing and the proposal talks about implementation of a new management information system. In the second part, the production process is proposed to purchase a new machinery to replace the existing laser. These two parts intend to use the time and cost more effectively in the contract management side and are hoping to be a great asset for customers and for the company Duo Form itself.

Logistics and supply of PCB for repair of notebooks
Grob, Filip ; Starý, Jiří (referee) ; Špinka, Jiří (advisor)
This diploma thesis deals with issues of inventory management and logistics controlling. These segments are one of most important instruments used in logistics. Theory of these logistic instrumens are used as a base for practical part of this diploma thesis, where is described and suggested methodology for inventory management of printed circuit board in repair center. This buffer inventory serves for securing performance of customer’s supplies in case of failure on repair line. Thereinafter is realized program in MS Excel interface for supplying leadership with main insistence to prevent order delay.

Operation measurement optimization
Barták, Pavel ; Doňarová, Jana (referee) ; Fiala, Alois (advisor)
This diploma work is aimed to measuring process, by measuring laboratory, during serial productions in international company Bosch Diesel s.r.o. Jihlava producer of common rail. Target of this diploma work is cross-check of evaluated dimensions, reengineering of incomming parts flow from production to measuring laboratory, measuring process, evaluation of results and pass results back to production. This will speedup all process and minimalist risk of production not O.K. products because of latest results from measuring laboratory. Is done analysis of present situation and base on it proposed different variants of solutions for reengineering of measuring laboratory.

Static analysis of suspension bridge variants
Zavřelová, Michaela ; Martinásek, Josef (referee) ; Vlk, Zbyněk (advisor)
The bachelor's thesis deals with the static analysis of individual models of suspension footbridges. A manual calculation of the cable was processed. The actual position of the cable was determined by calculation. The manual calculation was compared with the RFEM calculation program. Furthermore, the models were loaded with manually calculated loads. The bachelor's thesis deals with the influence of pylon deflection on the global deformations of cable and bridge deck during individual load cases and combinations. For one of the models, the optimization of construction was processed.

Suggestion and optimalisation of a private investor portfolio
Lády, Jiří ; Chovanec, Patrik (referee) ; Škapa, Stanislav (advisor)
This diploma work is focused on a suggestion of private investor portfolio and suggestion of questionnaire to determine a risk profile of a provate investor. Apart from basic investments theory, the thesis briefly describes characteristics and parameters of particular asset classes and suggests and optimises a risk portfolio for a private investor. Furthermore, a survey of this risk profile is conducted, so that the investor can use it himself/herself in management of his investments to best full fill his/her expectations.

Pixelated electrically small antenna
Turák, Samuel ; Kadlec, Petr (referee) ; Zechmeister, Jaroslav (advisor)
This bachelor thesis deals with the problematic of programming and implementation of binary evolutionary algorithms and their practical application for design of pixelated electrically small antenna for ISM band 868 MHz. Two binary evolutionary algorithms are introduced and implemented, both created in the programming environment Matlab. The basic antenna design and its optimization are performed by the program CST controlled by an in-house Matlab code. In the thesis, an empiric research of miniaturization and sensitivity of the electrically small antenna is conducted.This bachelor thesis deals with the problematic of programming and implementation of binary evolutionary algorithms and their practical application for design of pixelated electrically small antenna for ISM band 868 MHz.
