Computational simulation of cross-roll leveling of rods
Benešovský, Marek ; Vrbka, Jan (referee) ; Petruška, Jindřich (advisor)
Final thesis describes two variants of computational models to simulate cross-roll leveling of rods, which are based on the Lagrangian approach to describe the continuum. Implementation of both variants was performed in ANSYS software, and their main difference lies in the choice of the type of elements for the discretization. An integral part of this thesis is the description of the principle, which is an evaluation of the curvature of the rod after completion of the simulation leveling. In the other part of the work are presented the results, which are then compared with realized experiment and simulation algorithm for cross-roll leveling based on the Euler approach. The final part is dedicated to the optimal settings of the leveller.

Analysis and optimization of timber construction costs
Zvonař, Tomáš ; Vrbka,, Marek (referee) ; Tichá, Alena (advisor)
This diploma thesis deals with the cost analysis and cost optimization of an exact project of a wooden house in a construction company. The thesis is divided into two parts. The first part is the research part, where basic concepts are defined. The second part of this thesis is the practical part which includes a brief description of the concerned wooden house with its preliminary and final budget. Individual parts of these budgets are subject to the cost analysis. As a result of the cost analysis the price differences between the budgets are shown. In the next step the verification bill of quantities with an item based budget in the ÚRS price system is put together. It is used for comparison and determination of price differences. According to the obtained data, optimization of the preliminary budget is proposed. At the end of this thesis an overall evaluation of price differences and proposed measures are described.

Parametric budget estimation - Innovation of the method of determining bid prices in a construction company
Vrbka, Marek ; Comorek,, Martin (referee) ; Elingerová,, Helena (referee) ; Mésároš,, Peter (referee) ; Tichá, Alena (advisor)
Today's trend in construction is the emphasis on the most extensive unification. There are a number of building systems and technologies that can be clearly defined in terms of their technological solution. This trend opens up opportunities for innovative pricing approaches, or prices at which their construction products are offered by construction companies to their potential customers. From the customer's viewpoint, the offer price for the building, determined by the construction company, is the dominant part of the purchase price of the building work. The traditional way of determining the offer is the itemised budget. Creating itemised budgets is costly for companies and time-consuming, especially due to the costs of specialised budgets and their hardware and software equipment. The main idea of the dissertation is the effort to innovate in the area of budgeting of building structures designed for housing in the Czech Republic. The dissertation focuses more on the innovation of bidding in construction companies in the form of parametric budgeting. Parametric budgeting is an innovation based on parametric cost estimation methods. The principle of parametric budgeting correlates statistical analyses by calculating the cost of model cases with specific cases using the regression functions set for a given data set. A link between model and specific cases is spatial, technical, technological and material parameters. The dissertation’s overall objective is to evaluate in particular whether parametric budgeting makes it possible to increase the efficiency of the bidding process in enterprises. In the thesis are used calculation methods to determine construction costs in the form of item budgets. In addition, mathematical methods are used to determine the regression function of a particular data set for creating and examining cost estimation relationships. In the dissertation are used investment procedures to determine simple payback period, cash flow, etc.

Determination of Technical-economic Index for Wooden Structures with Help of Generated Data Base
Vrbka, Marek ; Tajbr, Aleš (referee) ; Krejza, Zdeněk (advisor)
This bachelor thesis describes wood structures and their structural systems along with their advantages and disadvantages. In the thesis calculation of technical-economic index (TEI) was performed for certain type of modern wood frame structure. From data analysis the author proposed two-stage application for determining the value of TEI of wood frame structures. In the first stage the author proposed methodology TEI; IC (technical-economic index, internal classifications), which is based on the principles used in the context of budgetary indicators. In the second stage the author proposed methodology TEI; CF (technical-economic index, complex formula). This methodology is based on calculation of TEI, where the default values are modified by coefficients reflecting influences affecting the value of TEI. The first stage is designed for implementation in the budgeting database software. The second stage is intended for implementation in software such as Microsoft Excel.

LABORARTORY BRNO
Petrík, Marek ; Vrbka, Jan (referee) ; Ponešová, Barbora (advisor)
The center of Brno is already full of all types of galleries and that is why i made just 30% of the exhibition space as is specified in the assignment and the rest is also considered in a solution that could help spawn Brno art. How have sociologists in their recent studies mentioned the transformation of the labor market is worth a new phenomenon, called coworking. We will more often work bursts and we will need work for more multiple employers at once. Several thousand supporters - Freelancers, found in this style of work and the sharing of popularity. Before working from home hey prefer shared coworking office. Platform of ART - Dynamic center for Brno - Laborartory!

Dynamic card of cost indicator of house
Vrbka, Marek ; Tajbr,, Aleš (referee) ; Krejza, Zdeněk (advisor)
This master thesis describes a detached house, requirements for the detached house, price, technical-economic index and card of cost indicator. The author performed an analysis of selected houses and itemized budgets of selected houses. Different shapes, technologies and solutions of materials are included in the analysis. The author, from the analysis, inferred the behavior of technical-economic index (TEI) of detached houses. The author described behavior in the particular and sub models. The author suggested methodology of calculation of the price data, the spatial data and the structure of price TEICF2 (technical-economic index, complex formula, version 2) of planned detached house. The author founded his methodology on particular and sub models. The principle of methodology TEICF2 consists in the analogy of the planned detached house with the model with same parameters. The author implemented TEICF2 into application dyCBI. Application dyCBI is working on Microsoft Excel.
