MULTI-OBJECTIVE OPTIMIZATION OF SCIENCE PARKS BASED ON QUALITATIVE EQUATIONLESS RELATIONS
Wouters, Hana ; Koráb, Vojtěch (referee) ; Hřebíček, Jiří (referee) ; Čapek, Jan (referee) ; Dohnal, Mirko (advisor)
Tato dizertační práce řeší optimalizaci vědeckých parků z hlediska potřeby zvyšování konkurenceschopoností regionů a potažmo celé ČR. Je koncipována pro investory, kteří chtějí realizovat projekt VP v různých regionech ČR nebo manažery již existujících vědeckých parků, kteří chtějí udělat další rozhodnutí. Možnost realizovat projekt VP platí pro všechny regiony, včetně regionů, které se dříve mohly spoléhat na dostupnost a těžbu nerostných surovin (tradičně těžba uhlí), jež v minulosti fungovala jako významný faktor pro rozvoj průmyslu a ekonomické aktivity. Tyto regiony se nyní musejí vyrovnat se ztrátou konkurenceschopnosti a přesunout své úsilí do oblasti rozvoje výzkumu a vývoje produkujícího inovace. Kvalitativní modelování je vhodné pro tak málo známé a komplexní systémy jako jsou právě vědecké parky (VP). Modely vědeckých parků obsahují proměnné různého charakteru a různých časových chování. Z tohoto důvodu jsou studovány rychlé a pomalé modely. Pro 11 pomalých proměnných je studován soubor 17 kvalitativních bezrovnicových vazeb typu (např. kvalita výzkumných a vývojových inženýrů, konkurenční status atd.) společně se souborem 14 kvalitativních bezrovnicových vazeb pro 10 rychlých proměnných typu (např. spolupráce mezi průmyslem a akademickými ústavy, výměna průmyslových informací apod.). V této dizertační práci jsou prezentována řešení rychlých a pomalých modelů ve formě souborů rychlých a pomalých scénářů a přechodů mezi nimi a jsou hledána optimální řešení. Analýza/optimalizace málo známých, nelineárních, multidimenzionálních systémů jako jsou vědecké parky je složitá a je obtížné vytvořit smysluplné a dostatečně přesné modely nestabilního chování. Systematická analýza řady kvalitativních řešení je hlavní částí disertační práce a jejím hlavním vědeckým přínosem. Jednotlivé kroky postupu tvorby modelu jsou názorně ilustrované na příkladech. Text obsahuje interpretaci dosažených výsledků a formulaci přínosů pro teorii a praxi.

Valuation of Economic Risk of Investor in Realization of Investment Project
Rusínová, Alena ; Dvořáčková, Šárka (referee) ; Hromádka, Vít (advisor)
This thesis is focused on assessing the economic risk for the investor in the implementation of the investment project. An investor's decision on the implementation of the project depends on the economic feasibility analysis identified outputs, these outputs are burdened by economic uncertainty, which raises the risk. Therefore, it is necessary to manage risk. The process of risk management consists of a phase of risk analysis and risk management phase. In the analysis phase is to identify risks, assessments of materiality and risk measurement. In the phase of risk management risks identified evaluate and establish measures to prevent their occurrence or impact.

Application of stochastic programming methods for the purpose of energy producing system
Šomplák, Radovan ; Mrázková, Eva (referee) ; Popela, Pavel (advisor)
This thesis deals with the evaluation of the strategic investment in the waste-to-energy plant development. The central supply of heat and the incineration plant connection can be provided for example by the distribution network. The objective is to find financially feasible solution regarding uncertain development of waste management and energy market. A heat supplies to district heating network significantly influences the strategic decision. A two-stage stochastic programming based on the scenarios and the GAMS software were applied to solve this task. The main contribution of this thesis is decision on crucial parameters of the waste-to-energy plant.

Optimization for the design of subsystems of energy-producing processes
Janošťák, František ; Bednář, Josef (referee) ; Pavlas, Martin (advisor)
This bachelor thesis focuses on the design of a combustion grate. The key factor is the lower heating value of waste, which has been modelled based on the data obtained from a real combustion grate. The goal is to develop a combustion grate, which will function effectively whilst changing the lower heating values. Possible scenarios of the problem are mathematically formulated and implenented in GAMS enviroment. The outcome of this work are the parameters of the combustion grate.

Network flow models for waste management
Janošťák, František ; Mrázková, Eva (referee) ; Pavlas, Martin (advisor)
This thesis is devoted to the construction of new waste-to-energy plants in a territory where is already another fossil-fuel power station in operation. The aim is to create a mathematical model and prove that those two devices are able to cooperate effectively using same technology. Exactly assembled model under real operating have characteristics of a mixed integer nonlinear programming. The optimization software GAMS is used for its calculation. The complexity of the model, however, is at a level that solutions in bad initial conditions ends in local optima, or not found at all. This thesis is devoted to the elimination of non-linearity using binary variables and heuristic so the task was solved with acceptable time limits to guarantee an optimal solution.

Selected financial optimization models
Bujnovský, Daniel ; Bednář, Josef (referee) ; Popela, Pavel (advisor)
This work is focused on models of optimal asset and liability management. The practical section illustrates various ways of modelling strategies depending on the problem formulation, chosen set of assets and the type of the used optimization technique. The main examples are portfolio immunization and the Yasuda-Kasai model together with the extended version of Markowitz model. The author provides across the work an overview of different financial risks and various tools for their measurement together with possible formulations of expected returns relevant to the studied models. The individual models are compared and often extended by other constraints in order to improve their practical applicability. From the point of view of the mathematical optimization several ways of input data generation are described for example by using the extended Brownian motion. All practical parts go hand in hand with illustrative pictures and codes. The necessary financial and mathematical theory is included as well.

Assessment of climate change impacts on selected ecosystem services in the Czech Republic: application of land use scenarios
Lorencová, Eliška ; Vačkářová, Davina Elena (advisor) ; Müller, Karel (referee) ; Cudlín, Pavel (referee)
Doctoral thesis abstract Assessment of climate change impacts on selected ecosystem services in the Czech Republic: Application of land use scenarios MSc Eliška Lorencová Climate and land use change are recognized as the greatest global environmental problems. Both considerably impact delivery of crucial ecosystem services, such as carbon sequestration, water flow regulation, erosion control, and food and fibre production. By combining future projections of ALARM scenarios (for years 2020, 2050 and 2080) with modelling of ecosystem services, the study aims to evaluate climate change impact on selected ecosystem services (carbon storage and sequestration, erosion control and sediment retention) in the Czech Republic. This study provides quantitative as well as spatially explicit analysis of the impacts on selected ecosystem services in the Czech Republic. Performed ecosystem service assessment indicates that spatial distribution of provision of ecosystem services, such as carbon storage and sequestration, sediment retention reflects the projected future land use changes. In case of carbon sequestration, SEDG scenario shows the lowest carbon sequestration rates accounting for 37,029.6 Gg C within the period 2000-2080. Stable vegetation cover is one of the factors that play important role in amount of sediment...

Assessing ecosystem services and the alternatives of their future development in UNESCO Biosphere Reserves
Harmáčková, Veronika Zuzana ; Vačkářová, Davina Elena (advisor) ; Cudlínová, Eva (referee) ; Pechanec, Vilém (referee)
The provision of ecosystem services within social-ecological systems is influenced by multiple environmental and anthropogenic driving forces, affecting natural ecosystems. At the same time, the capacity of ecosystems to concurrently provide different types of ecosystem services is inherently limited. Thus, ecosystem changes and their effect on ecosystem services have direct implications for human existence and well-being. The aim of this thesis is to present a modelling approach to assess regulating, provisioning and cultural ecosystem services and to quantify their potential trade-offs, illustrated by two case studies carried out in selected UNESCO Biosphere Reserves in the Czech Republic, Třeboň Basin Biosphere Reserve and Šumava Biosphere Reserve. Both of the selected case study areas are characterized by high levels of natural and cultural assets and challenges regarding future landscape management. In this study, first the social-ecological dynamics within the study areas was analysed by creating participative scenarios through collaboration with local stakeholders, eliciting their preferences regarding future landscape development to 2050. Second, the impact of the scenarios on ecosystem services and their trade-offs were assessed using a combination of spatially explicit models and...
