Are scouts really more honest?
Sedlická, Monika ; Zajíček, Miroslav (advisor) ; Tříska, Dušan (referee)
Using two experiments, where children either rolled dice or solved a matrix task, we examined whether scouts are more honest than non-scouts. In the first experiment, participants completed a matrix task. The papers were then shredded, and participants self-reported the number they had correctly solved. After analysing the results, we found that 10.81 % of scouts and 13.04 % of non-scouts lied. This difference, between the honesty of scouts and non-scouts, was not statistically significant. There was no perceived effect from being scout on the individual's honesty, as well as from taking the scout promise, or years of experience in a scout organization on the scout's honesty. In the second experiment, participants rolled the dice privately. According to value rolled, participants could either take (1, 2, 3), or leave (4, 5, 6), a Kinder chocolate reward. Statistically, participants would be expected to take the reward 50 % of the time. This was the case for the scouts group, the results did not differ statistically from 50:50, but not for the non-scouts. However, the difference between scouts and non-scouts was not statistically significant, indicating that there is no significant difference in honesty between scouts and non-scouts. Thus, our hypothesis that scouts are more honest than non-scouts was not supported.

Mathematical Programs for Dynamic Pricing - Demand Based Management
Hrabec, Dušan ; Karpíšek, Zdeněk (referee) ; Hoff, Arild (referee) ; Haugen, Kjetil Kare (advisor)
Tato disertační práce se zabývá vývojem, modelováním a analýzou poptávkově orientovaných úloh, které zahrnují marketingová, operační a logistická rozhodnutí. Úlohy jsou zvoleny tak, aby mohly být dále rozšířeny o koncept tzv. dynamického oceňování a jiných dynamických marketingových rozhodnutí. V práci jsou využity dvě základní poptávkově orientované úlohy: a) úloha kolportéra novin, která je zvolena pro její jednoduchou formu a která tak slouží jako nástroj pro ilustrativní ukázky rozhodovacích procesů v podobných typech úloh, a b) úloha návrhu dopravní sítě, kde jsou využity některé výsledky a znalosti získané při řešení úlohy kolportéra novin. Kolportér (či obecně maloobchodník) čelí náhodné poptávce, která může být postupně ovlivněna oceňováním, marketingovými (tj. reklamními) rozhodnutími a nakonec jejich kombinací. Poptávka obsahuje tedy náhodnou složku, která je pomocí přístupů stochastické optimalizace modelována ve specifickém tvaru (tj. aditivní či multiplikativní tvar). Závislost cena-poptávka je zachycena pomocí nelineární klesající poptávkové funkce, zatímco (vhodná) reklama vede ke zvýšení poptávky (běžně rostoucí s-křivka či konkávní funkce). Výsledky získané při řešení úlohy kolportéra novin s oceňováním jsou následně využity v úloze návrhu dopravní sítě. Tato stochastická úloha je modelována (reformulována) pomocí dvou přístupů stochastické optimalizace: wait-and-see přístup a here-and-now přístup. Jelikož tato implementace vede na lineární či nelineární celočíselnou (navíc scénářovou) úlohu, jsou v práci zmíněny taky výpočetní nástroje. Autor pro řešení používá (původní) tzv. hybridní algoritmus, což je kombinace heuristického (genetického) algoritmu a nástroje optimalizačního softwaru. Potenciální aplikace sestavených modelů, obzvláště v oblasti odpadového hospodářství, jsou diskutovány v závěrečné části disertační práce.

Application of the multicriterial decision making for an investment portoflio
Mulakaeva, Alfiia ; Brožová, Helena (advisor) ; Adam, Adam (referee)
The aim of this thesis is the selection of suitable investments (shares) for a particular investor and the creation of an investment portfolio with the help of multiple-criteria decision analysis.
The first part of the work summarizes the theoretical background of security portfolio creation, acquaints the reader with the concept of stocks and methods of analyzing equity instruments. It also provides an overview of the functioning of the capital markets generally and specifically in the Czech Republic. The second part focuses on the approaches and procedures for solving decision-making problems. Methodological apparatus includes systems analysis, linear optimization and multi-criteria decision making methods. The third part of the thesis concentrates on the application of this methods for the formation of the investment portfolio in the presence of multiple criteria. Most important ratios of the stock market and the magic triangle return, risk and liquidity are reflected in equities choice. Stock selection is carried out by using models of multi-criteria evaluation of alternatives in two rounds and portfolio composition is determined by the classical model of linear programming. As a result, investor gets a recommendation for his portfolio, which contains a number of shares of selected companies on the Czech market. This procedure of creating the portfolio can be used by individual investors, financial advisors and brokers and complement their knowledge, experience and intuition.

Prediction of crop yields using satellite remote sensing
Lukas, V. ; Trnka, Miroslav ; Semerádová, Daniela ; Rajdl, Kamil ; Balek, Jan ; Štěpánek, Petr ; Zahradníček, Pavel ; Hlavinka, Petr ; Žalud, Zdeněk
Knowledge of the crop yield with sufficient lead time prior to harvest is crucial for both the farm management and the agro-food sector policy. The aim of this study was to test feasibility of developing crop yield forecasting model in Czech Republic for winter wheat, spring barley and oilseed rape based on 2000-2014 database of vegetation indices Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI2) from Moderate Resolution Imaging Spectroradiometer (MODIS) on Terra satellite in form of 16-days composites. An average yield data were collected for 14 selected districts in the Czech Republic that represent the regions with more intensive agricultural production among varying climate and topographic conditions. The viability of the concept was proven in years with significant yield decline i.e. 2000, 2003, 2006 and 2012, when yields of cereals were significantly affected by occurred drought periods. More stable regression results were achieved in the most productive areas such as Olomouc and Prerov, whilst models in highland regions were influenced by lower acreage of three modelled crops and higher prevalence of fodder crops. In most cases, EVI2 showed higher correlations to the crop yield together with using an average value of all composites during vegetation period.

Hofrichterová, Kateřina ; Bruckner, Tomáš (advisor) ; Kodym, Oldřich (referee)
The thesis is focused on testing the banking software. The first part is contained introduction to the topic, introduced the project, including its objectives, the nature of the application, my role in it. Further described is a method Case study used throughout the work. The company is a researcher of the project for the client. The first objective is to describe the company's testing methodology by which the project progressed during, compare it with other methodologies with regard to their robustness, the degree of organization of work and domestic allocation. The second objective is to determine the bottlenecks including the determination of improvement. Each project is unique, so is suitable, another degree of organization. A control method of the project is agile. It is therefore expected framework anticipating complications and subsequent resolution of other areas to occur. The work defines the cause bottlenecks as the internal factor (human labor), external factors (legislative changes). Mapped was not only the current situation but also outlined the cause of the problem. And the third in terms of value-added most important goal is to design verification solutions experts. At work I described ways of solving problems. I woke them both employees solver side, so people from client companies. Experts from the client know good practices in the company and are able to assess the suitability due to the nature of society. Collaborators supply side, meanwhile, have extensive experience from similar projects. Their opinion on the issue can bring effective application of the Recommendation. The biggest benefit is not only the approval but also the subsequent implementation in the course of the entire project.
