Analysis of inflation in the Czech Republic
Holakovská, Adéla ; Formánek, Tomáš (advisor) ; Dlouhá, Zuzana (referee)
This work is focused on econometric analysis of inflation in the Czech Republic, there is also reported an analysis of inflation in Austria and continuity of both countries to the dominant German economy. The inflation with its forms and possibilities of measuring is described in the first part of this work. There is also mentioned the influence of Czech national bank on the inflation. Next, there is shown the impact of foreign exchange rates and inflation. Consequently there are described characteristics of time series, which are important from viewpoint of construction of econometric models. Next, there is described theory of econometrics analysis, focused on ordinary least squares method and method of instrumental variables. The empirical part contains econometric analysis of inflation itself, using models described in theoretical part. Moreover, this work includes other models, coming out of economic hypothesis. Firstly, it analyses inflation in Germany as the reference country. Secondly, further analysis performs inflation in the Czech Republic and Austria. Finally, an analysis based on ERPT (exchange rate pass-through) models is given. In conclusion, the results are well summarized and compared.

The effect of european economic integration on international trade
Tománek, Ondřej ; Dlouhá, Zuzana (advisor) ; Čermáková, Klára (referee)
This bachelor thesis aims to economic integration of Europe. In the first part, it focuses on issues of stages of economic integration. The second part is dedicated to Europen Monetary union, its advantages and disadvantages. The next part is dealing with history and development of EU, CEFTA, EFTA, BAFTA. In final part, we use gravity model of international trade to analyze influence of each mentioned integrated group. Panel dataset consists of 27 776 observations of 23 years (1993-2015). Our results are consistent with other researchers, that are dealing with this issues. But some differences have been found. Preferential trading areas increases international trade, but the EMU coefficient is negative. Later on, we compare calculated potential exports of the czech republic to real exports to neighboring countries.

Vehicle routing problem in practice
Tuan Hoang, Anh ; Dlouhá, Zuzana (advisor) ; Kuncová, Martina (referee)
Nowadays, one of the most widely used optimization problem is a travelling salesman problem. That is only the basic model, which is modified by various restrictions and enlargements. In the first part of this bachelor thesis we will focus on theory of distribution problems and their solutions. On the other hand in the second part we will apply the knowledge from the first part to the real task, which requires modifications. We will use the data of the supply company that delivers their orders in Prague with the limited capacities of the vehicles. We will find out the differences between minimizing the total distance and minimizing the total time for delivery, as the distance and time are not linearly dependent. It will be needed to decide, where will be an optimal location for opening the second branch. To solve this tasks, we will not use only heuristic methods for manual calculation, but also optimization software.

Travelling around Vietnam-application of Travelling Salesman Problem
Pham, Thuy Trang ; Dlouhá, Zuzana (advisor) ; Fábry, Jan (referee)
The circular traffic problem, also known as the Travelling Salesman Problem (TSP) belongs to a group called distribution problems, which is one of the significant group of linear programming. These tasks can be used in many applications areas such as production planning, logistic or travelling. This thesis deals with the application of TSP or its modification to find the optimal route among selected Vietnamese destinations. The aim is to find the best circuit among 20 places out of 37 considering the cost and time. The first chapter concentrates on the general theory of linear programming including the description of economical and mathematical models of the selected distribution problems. The main part of this thesis focuses on The Travelling Salesman Problem itself and its practical application

Analysis of migration in the Czech Republic on the district level
Houšková, Helena ; Formánek, Tomáš (advisor) ; Dlouhá, Zuzana (referee)
This bachelor thesis focuses on internal migration in the Czech Republic on the district level. The aim of the thesis is to explain the relative number of immigrants to particular districts, relative number of emigrants from districts and mainly their difference - growth in the year 2013 with the help of different factors, such as criminality, unemployment, area, and so on. The factors are named and their influence on the relative number of immigrants, emigrants and growth is predicted. Then these data are analysed and three different models are constructed to explain the growth of population. In the first model all districts are taken into account. In the second model three districts of Prague are removed and in the last one, in addition to Prague, central districts of Brno and Ostrava are also removed. After comparing the three models we find out that models are quite similar and not all factors influence the growth of population as we expected.

The Estimation of Probability of Default Using Logistic Regression
Chalupa, Tomáš ; Dlouhá, Zuzana (advisor) ; Formánek, Tomáš (referee)
The aim of this work is to develop a suitable model that estimates a probability of default of client's loan. As estimation method was used a logistic regression and a probit regression and two definitions of default, 60 and 90 days overdue. The work describes the method of construction, estimation and testing of scoring models and a structure of dataset, which was used in the practical part. Firstly, it was created a theoretical model that was later confronted with estimates. Estimated models were compared by described statistics as McFadden R^2, the ability to diversify was investigated by the Lorenz curve and by the Gini coefficient. It was found that the logistic and the probit regressions have almost the same results, and that 90 days is preferable definition of default than 60 days.

Using a combination of optimization, simulation and multiple-criteria decision analysis methods for a selection of heat sources in a residential building
Murčová, Veronika ; Kuncová, Martina (advisor) ; Dlouhá, Zuzana (referee)
The aim of the thesis is to select a suitable heat source for a residential building using simulation modeling and multiple-criteria decision analysis. The market is offering plenty of possibilities, thus the part of this thesis is dedicated to description of main characteristics and pros and cons of most common heat sources (e.g. coal, biomass, natural gas, electricity, heat pumps). There are many ways to decide which source is an optimal solution for a house. In this thesis, there are presented four possible approaches: decision based on the analysis of the total costs of the source and the methods WSA, TOPSIS and ELECTRE III. In the end, the results of these methods are summarized together with the qualitative factors which are also considered in the decision making process.
