Measurement of Production Overall Equipment Effectiveness
Žanda, Miroslav ; Novák, Josef (referee) ; Píška, Miroslav (advisor)
The diploma work deals with measurement of Production Overall Equipment Effectiveness in manufacturing company Alfa. Firstly, is processed the theoretical part concerning general production, TPM, lean manufacturing and OEE. After than is described the company, monitored device and technology used by the device. In the final section is evaluated the OEE for January, February and March; analyze downtimes, mistakes and losses and their solutions are proposed. The last chapter is devoted to the economic evaluation of the proposal.

Proposal for the increased effectiveness of production operation of sheet metal covers at ISOTRA company
Hykel, Lukáš ; Blachut, Bohumír (referee) ; Kubík, Roman (advisor)
The thesis deals with the optimization of production lines cover sheets for external blinds. The aim of this work is to propose appropriate investment in line for expansion of capacity and the reduction of risks in the form of cooperation. To achieve the objective I propose two alternative solutions. Combination of these two variants has been optimized with regard to investment in capacity expansion, reduce risk and achieve a fast return on investment. The conclusion describes the individual prices of investment items and annual profit from the newly formed water jet technology.

DISCONNECTOR PARALLEL CURRENT PATHS OPTIMIZATION
Görig, Tomáš ; Tůma, Jan (referee) ; Dohnal, Petr (advisor)
The objective of this master´s thesis is diagnostic the actual disconnector current path that is unevenly stressed by nominal current. The most stressed parts are excessively heated. In next part are projected a few options to optimize the current path. The options are verified by simulation. The best option is recommended to the submitter.

Evolutionary Analogue Amplifier Optimisation
Bielik, Marek ; Zachariášová, Marcela (referee) ; Bidlo, Michal (advisor)
Táto práca demonštruje možnosti využitia evolučných algoritmov, konkrétne evolučných stratégií, v doméne dizajnu analógových zosilňovačov. Do implementácie je zahrnutý ngSPICE simulátor, ktorý je použitý na vyhodnotenie optimalizovaných riešení a v práci je navrhnutých niekoľko vyhodnocovacích metód. Práca tiež zahŕňa experimenty a ich výsledky, ktoré boli použité na určenie najvodnejších parametrov evolučných stratégií. Cieľom bolo optimalizovať hodnoty súčiastok jedno a dvoj stupňových zosilňovačov s bipolárnymi tranzistormi v zapojení so spoločným emitorom. Výsledkom je nástroj umožňujúci návrh zosilňovačov s ľubovoľným zosilnením v rámci možností daného obvodu bez použitia akéhokoľvek matematického aparátu.

Design of urban area using advanced technologies
Nováček, Michal ; Apeltauer, Tomáš (referee) ; Remeš, Josef (advisor)
The subject of the thesis is to define sunlight illumination as a building-influencing physical factor from the perspective of the technical standards in the Czech Republic. It aims to optimize the draft making process, and a quality of selected technical standards for sunlight illumination in the Czech Republic. In conclusion there is an example of a sunlight illumination analysis in different ways.

Rationalization project of workplace for Hot-water Heater welding
Varjan, Matúš ; Heinl, Zdeněk (referee) ; Rumíšek, Pavel (advisor)
The aim of the thesis is to rationalize the water heaters welding area in Tatramat company - ohrievače s.r.o. The rationalization consists of three parts. The first part deals with the arrangement of the workplaces, the second part re-evaluates the monthly production planning. The third part describes in detail the production of one type, which based on simulations created in the simulation software Witness, compares the recorded time in company informartion system Orfert to the real production time in the operation. Each individual part offers optimization proposals and merging them into one unit, will create an efficient, transparent and economically value adding rationalization of the water heaters welding area.

Optimization in engineering problems
Čepl, Ondřej ; Popela, Pavel (referee) ; Mrázková, Eva (advisor)
This bachelor's work engages optimization and its improvement in engineering cases. There are defined basic terms and optimization's cases, basic characteristics of the optimization case are accounted and basic methods of their solutions are understated. These teoretic findings are availed by optimization of the measurements of three-bar truss, whereas there are solved two options of optimization's case. Mathematical models are implemented to programm GAMS and at the conclusion is accomplished disccusion of accomplishments.
