Možnosti využití optimalizačních metod při plánování osetí zemědělské půdy

Bulíčková, Anna January 2015 (has links)
Bulíčková, A. The opportunities of using optimization methods for crop planning. Diploma thesis. Brno: Mendel University, 2015. This diploma thesis deals with the opportunities of using optimization methods as a decision-making tool for the structure of crop rotation. The aim of this thesis is to consider the possibilities of using the methods of the operation research in crop planning and suggest appropriate optimization tools. The suitable model will be applied to a chosen agricultural company. The important terms of the farmland, crop rotation and optimization methods using in agriculture are described in this thesis. Subsequently, the structure of agricultural production in ZD Třebelovice is analyzed and appropriate optimization model suggested. The problem is solved by using the MS Excel software. The example of ZD Třebelovice is used for the generalization in the agricultural sector.

Zpracování odpadu z pily ve Slavonicích

Kubek, Tomáš January 2015 (has links)
Diploma thesis deals with proposal of elaboration of waste from sawmill in Slavonice. Solves condition of current operations and technological equipment of the company. It also deals with three variants of the technological organization and mechanization of elaboration of waste. The first variant solves briquetting line, the second is focused on the pelletizing line and the third part constitutes sorter sawmill waste. All of the mentioned variants are supported by the drawings. Diploma thesis includes economic evaluation of the solutions, where are assessed hypothetical realization and operation costs of the line for elaboration of the waste. From all of the mentioned variants is selected the most advantageous variant - sorting of the waste

Aplikace optimalizačních metod v hydrologickém modelování / Application of optimization methods in hydrological modeling

Jakubcová, Michala January 2015 (has links)
Finding the optimal state of reality is the main purpose of the optimization process. The best variant from many possibilities is selected, and the effectiveness of the given system increases. Optimization has been applied in many real life engineering problems as in hydrological modelling. Within the hydrological case studies, the optimization process serves to estimate the best set of model parameters, or to train model weights in artificial neural networks. Particle swarm optimization (PSO) is relatively recent optimization technique, which has only a few parameters to adjust, and is easy to implement to the selected problem. The original algorithm was modified by many authors. They focused on changing the initialization of particles in the swarm, updating the population topology, adding new parameters into the equation, or incorporating shuffling mechanism into the algorithm. The modifications of PSO algorithm improve the performance of the optimization, prevent the premature convergence, and decrease computation time. Therefore, the main aims of the presented doctoral thesis consist of proposal of a new PSO modification with its implementation in C++ programming language. More PSO variants were compared and analysed, and the best methods based on benchmark problems were applied in two hydrological case studies. The first case study focused on utilization of PSO algorithms in inverse problem related to estimation of parameters of rainfall-runoff model Bilan. In the second case study, combination of artificial neural networks with PSO methods was introduced for forecasting the Standardized precipitation evapotranspiration drought index. It was found out, that particle swarm optimization is a suitable tool for solving problems in hydrological modelling. The most effective PSO modifications are the one with adaptive version of parameter of inertia weight, which updates the velocity of particles during searching through the multidimensional space via feedback information. The shuffling mechanism and redistribution of particles into complexes, at which the PSO runs separately, also significantly improve the performance. The contribution of this doctoral thesis lies in creation of new PSO modification, which was tested on benchmark problems, and was successfully applied in two hydrological case studies. The results of this thesis also extended the utilization of PSO methods in real life engineering optimization problems. All analysed PSO algorithms are available for later use within other research projects.
