The racionalization of machining of gearboxes
Sádlo, Dominik ; Růžička, Petr (referee) ; Sliwková, Petra (advisor)
Content of the thesis is the proposal of new technology using machining centres, including five controlled axis. Benefit of implementation the new nechnology is investigated at machining example, which is the gear housing of a single stage gearbox, manufactured in the company. In the first part of the thesis, the general properties of gearboxes and their housings are analyzed, as well as the procedure of the current proces of the machining representative. In practical part of the thesis is proposed necessary tool equipment and jig equipment, needed for machining of the part. After that are analyzed and filled in time studies, provided by manufacturers of machining centres. On the bases of these studies, were calculated operating times and operating costs per one piece of the housing. In the part of technical and economical evaluation is calculated the return of initial investment, including costs for byuing new machining cente and cutting tools equipment. Finaly are evaluated the overal benefits of the new technology, given the needs of the company.

The costs of single phase of the building life cycle
Černý, Ondřej ; Vaňková, Lucie (referee) ; Krejza, Zdeněk (advisor)
The bachelor’s thesis determines the costs of individual phases of a building’s life cycle. The thesis explores a very broad subject which entails a variety of topics. The theoretical part concerns itself with building in general, costs of individual phases of a building´s life cycle and pricing in the Czech Republic. In its practical part, the thesis primarily dissects determining costs for the utility, maintenance, repair and reconstruction of a building during its life cycle. The process for the calculation of the total sum of financial costs in individual phases of the life cycle is shown in a table, which contains the costs for individual phases of the building’s life cycle.

Drainage of sewage from expanding housing development
Studený, Martin ; Kejvalová, Eva (referee) ; Ručka, Jan (advisor)
This bachelor thesis deals with the technical-economical study, which compares the investment, operating and total costs of the given variants of drainage in the expanding development with regard to the variable number of considered real estate in the development. The theoretical part deals with variants of the technical solution of the case study. In the practical part of the thesis a technical-economic study is conducted, where the individual variants are elaborated in terms of investment, operating and total costs of the variable number of considered real estates in the development and their mutual comparison with respect to property law relations.

Evaluation of Construction Project from aspect of Whole Life Costs
Foitlová, Lucie ; Holá, Michaela (referee) ; Hromádka, Vít (advisor)
The theoretical part deals at the beginning with evaluation of effectiveness of the project, as well as with the information about individual stages of the life cycle of the building, wear and tear of the buildings, lifetime of the elements and whole life costs of the building that are of particular interest to the investor. In conclusion, there are mentioned wastes and emissions. The thesis is completed by a case study of the family house where the whole life costs of the building life cycle are solved.

Optimization of large technology compound design
Krňávek, Ondřej ; Kršík, Jakub (referee) ; Nevařil, Aleš (advisor)
This thesis deals with the optimization of the structural design of large technology compounds. The main emphasis is placed on the participation of available optimization instruments in the design of supporting structures of these constructions. The introductory part is primarily focused on the optimization itself. In this part are further specified also used optimization methods, computational finite element method, implemented code checks and calculation of cost of construction. The main part is dedicated to application of optimization procedure for the design of steel supporting structure of the auxiliary technological object of thermal power plant. The objective criterium shall then constitute the total cost of construction works along with operating costs. For the solution is used Scia Engineer software together with optimization module Scia Engineer Optimization Toolbox. The whole analysis is presented comprehensively from the description of computational model to results evaluation. The attention is paid to the optimization task settings, technical solution of optimization, optimization methods deployment and during the calculation process (especially to the development of objective function values and desing constraints during the optimization solution).

Incineration plant of middle treatment capacity – flue gas cleaning system
Krejčí, Tomáš ; Kropáč, Jiří (referee) ; Bébar, Ladislav (advisor)
Analysis of the regional energy supply, shows that suitable alternative may be a combination of primary energy sources with the municipal solid waste to energy plant. Starting from the fact that the regional thermal energy needs are characterized by smaller power demand, but relatively significant seasonal fluctuations in heat supply. These factors limit the processing performance of the considered waste to energy plant that could be included in the system of regional energy supply. The aim of the thesis was to propose adequate treatment capacity for regional waste to energy plant and explore alternative solutions in off-gas cleaning for exhaust gases generated during incineration of MSW. The balance sheets of two alternative solutions off gas cleaning are part of the thesis, both in terms of material and energy consumption. Presented evaluation of economic demands alternative arrangement of off gas cleaning includes operating costs and the impact on earnings from energy production.

Optimization of Operating and Financial Costs in Retail Business
Střeštíková, Iveta ; Ing.Richard Surman (referee) ; Kocmanová, Alena (advisor)
The topic of the diploma thesis is cost optimization in the company. The concept of optimization hides the effort to modify costs in order to achieve the best economic result of the company. In order to properly analyze and subsequently design the necessary measures, it is necessary to obtain a theoretical knowledge of the costs. The first part of the thesis contains theoretical knowledge. The second part deals with cost analysis and concrete areas that are most suitable for potential savings. The last part contains suggestions that should lead to savings.

Specifics of Passive Houses
Hortová, Michaela ; Chovancová, Jitka (referee) ; Kocourková, Gabriela (advisor)
The aim of this work is to extend understanding and knowledge of the problems of low-energy and passive houses. The theoretical part is focused on defining the characteristics of low-energy and passive houses. In practical part I analyze and compare three real houses. One of them is the passive house. This analysis is extended of assessment of the residents behavior.

Life Cycle Costs of Property Owned by the City
Vlastníková, Tereza ; Bartošová, Hana (referee) ; Hromádka, Vít (advisor)
The master thesis focuses on problems connected with the life cycle cost of property owned by the city. It analyses general issues of the life cycle cost of construction, but it mainly analyses the ways in which local authorities manage their properties and their cost. Those methods are applied in a case study, that addresses the cost and management of swimming pool sites which are owned by the city Brno.
