Ant Colony Optimization: Implementace a testování biologicky inspirované optimalizační metody
Havlík, Michal
Havlík, M. Ant Colony Optimization: Implementation and testing of bio-inspired optimization method. Diploma thesis. Brno, 2015. This thesis deals with the implementation and testing of algorithm Ant Colony Optimization as a representative of the family of bio-inspired opti-mization methods. A given algorithm is described, analyzed and subsequently put into context with the problems which can be solved. Based on the collec-ted information is designed implementation that solves the Traveling sale-sman problem. Implementation contains graphical user interface to track the algorithm. Implementation is further optimized using parallel programming and other methods. Finally the implementation compared and summarized results.

Use of distribution of tasks in construction company
Repoň, Patrik ; Fábry, Jan (advisor) ; Skočdopolová, Veronika (referee)
Bachelor thesis deals with distribution of tasks, which have utility in the construction company. The aim is to apply these distribution of tasks to problems with which the construction company often meets, and to reach an acceptable solution that will help to streamline production, save working time or financial recourses. Bachelor thesis is divided into two parts. The first part is a theoretical part, which presents problems in construction companies in general, as well as the application of different types of distribution of tasks. Furthermore, we face mathematical models of these tasks and with description of optimization software LINGO, which we will use to resolve them. In the practical part the distribution of tasks are applied to concrete problems and real data. The final part contains an overall assessment of the results.

Creating an Android application with help of the nutrition problem
Havlík, Vratislav ; Kobzareva, Maria (advisor) ; Fábry, Jan (referee)
The main target of this bachelor thesis is to create an Android application. The aim of this application is to use household resources effectively with help of an optimization. The user chooses his own way of the optimization to his satisfaction. Application uses linear programming, more precisely a nutrition problem. In the first part the thesis deals with linear programming in general, in the second part the nutrition problem is introduced, the third part is dedicated to optimization of a healthy diet, in the fourth part Android application fundamentals are showed and in the final part the thesis focuses on the application itself.

Robot vision with industrial robots Kuka
Krutílek, Jan ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
Diploma thesis deals with a robot vision and its application to the problem of manipulation of coincidentally placed objects. There is mentioned an overview of current principles of the most frequently used vision systems on the market. With regard to the required task to be solved, there are mentioned various possibilities of using basic softsensors during the recognition of different objects. The objective of this Diploma thesis is also programming and realization of a demonstration application applying knowledge of PLC programming, knowledge of expert programming KRL language (for KUKA robots), knowledge of designing scripts for smart camera in Spectation software and knowledge of network communication among all devices used in this case.

Optimization of internal material flow
Kovář, Miroslav ; Veverka, Petr (referee) ; Simeonov, Simeon (advisor)
This thesis refers about the optimalization of internal business logistics system. This thesis want to explore and propose new solutions to the system of internal transport of material in a manufacturing company. The aim is find a suitable methodology for the problem and aplication this methodology to the particular case. The practical part describes the specific case of the production system in the Bosch Diesel s.r.o. at his plant in Jihlava. Description includes an overview of the current state of the logistical arrangements and problems that a rise from the current state. Compares the current state with the proposed state and investigates the various pros and cons. Part of the analysis is a computer simulation of the transport system, which has been support to confirming the appropriateness of the proposed solutions.

Stochastic Programming Algorithms
Klimeš, Lubomír ; Mrázková, Eva (referee) ; Popela, Pavel (advisor)
Stochastické programování a optimalizace jsou mocnými nástroji pro řešení široké škály inženýrských problémů zahrnujících neurčitost. Algoritmus progressive hedging je efektivní dekompoziční metoda určená pro řešení scénářových stochastických úloh. Z důvodu vertikální dekompozice je možno tento algoritmus implementovat paralelně, čímž lze významně ušetřit výpočetní čas a ostatní prostředky. Teoretická část této diplomové práce se zabývá matematickým a zejména pak stochastickým programováním a detailně popisuje algoritmus progressive hedging. V praktické části je navržena a diskutována původní paralelní implementace algoritmu progressive hedging, která je pak otestována na jednoduchých úlohách. Dále je uvedená paralelní implementace použita pro řešení inženýrského problému plynulého odlévání ocelové bramy a na závěr jsou získané výsledky zhodnoceny.

Solving of partial differential equations by Fourier method
Barvenčík, Oldřich ; Opluštil, Zdeněk (referee) ; Nechvátal, Luděk (advisor)
Bachelor thesis is a survey text which deals with solving partial deferential equations by Fourier method, i.e. method when we look for a solution of (initial) boundary value problem in form of the infinite Fourier series. The key step is a hypothesis that the solution can be expressed in form with separated variables, therefore the method is sometimes called separation of variables method. The essence can be demonstrated on parabolic and hyperbolic homogeneous problems. In the thesis both types in one (space) dimension are systematically analyzed, at first homogeneous problem, then homogeneous one with non-homogeneous boundary conditions and finally completely non-homogeneous problem.

Design of equipment for steam generation and superheating
Jakeš, Martin ; Gottvald, Jakub (referee) ; Nekvasil, Richard (advisor)
This thesis describes the design of a new circuit for the production of superheated steam instead of the original heat exchanger, which showed frequent failure. In the introduction is disassambling the problems of the existing heat exchanger and the proposed method of solving the problem. Proposed is a new process circuit consisting of a heat exchanger to heat the steam, separator and heat exchanger for superheated stream. Gradually, the work both heat exchangers are designed thermal and strenght. In the thermal part is modeled all process circuit and calculated in the program ChemCad. The strength calculation is solved analytically according to EN 13 445, then all dimensions of heat exchangers are optimized. In the conclusion is verified by metod of finite element critical part of the exchanger. After successful completion of the design thermal and strength calculation was made relevant drawing documentation.
